Christians are called to a relentless warfare against sin. We are to put sin to death. The word that Christians have used to describe this over the centuries is mortification. It comes from the same word from which we get our English word mortal—subject to death, and mortuary—a place where the dead are taken.

To mortify means to put to death. This word gets to the heart of the conflict every Christian has with sin. It occurs twice in the New Testament—once in Colossians 3, and a second time in Romans 8: “If you live according to the sinful nature, you will die; but if by the Spirit you put to death the misdeeds of the body, you will live” (8:13).

The impulse to sin keeps landing in new ways in your life, and it has to be dealt with. Every day, something will happen that could provoke pride, or envy, or self-pity in you. Every day, another situation will arise that might lead you into impatience, ingratitude, or sins of the tongue.

You have to continually mortify temptations to sin. So, putting sin to death is not a one-time deal. We are always in this business of mortifying the flesh. As mentioned earlier, John Owen says in his book The Mortification of Sin, “Always be killing sin or it will be killing you.” Your life is like a battlefield, with an enemy who is always contending against you.

Have you not found it to be true of you, even this week, that every day you are provoked to new sins? Can you identify one impulse to sin from this past week?


4. The duty itself, "Mortify the deeds of the body,"

 a. What does ‘the body’ mean? Same as the flesh as early in the verse 

1.) [Romans 6.19]- I speak after the manner of men because of the infirmity of your flesh: for as ye have yielded your members servants to uncleanness and to iniquity unto iniquity; even so now yield your members servants to righteousness unto holiness. 

2.) [Romans 6.6]- Knowing this, that our old man is crucified with him, that the body of sin might be destroyed, that henceforth we should not serve sin. 

b. What by the deeds of the body? 

1.) [Galatians 5.19]- Now the works of the flesh are manifest, which are these; Adultery, fornication, uncleanness, lasciviousness

c. What by mortifying of them? 

1.) [Romans 6.6, 8]- Knowing this, that our old man is crucified with him, that the body of sin might be destroyed, that henceforth we should not serve sin. Now if we be dead with Christ, we believe that we shall also live with him: 2.) [Romans 6.3-5]- Know ye not, that so many of us as were baptized into Jesus Christ were baptized into his death? Therefore we are buried with him by baptism into death: that like as Christ was raised up from the dead by the glory of the Father, even so we also should walk in newness of life. For if we have been planted together in the likeness of his death, we shall be also in the likeness of his resurrection: 

3.) [Galatians 5.17]- For the flesh lusteth against the Spirit, and the Spirit against the flesh: and these are contrary the one to the other: so that ye cannot do the things that ye would. 

5. The promise unto this duty is life a. [Galatians 6.8]- For he that soweth to his flesh shall of the flesh reap corruption; but he that soweth to the Spirit shall of the Spirit reap life everlasting. 

b. [1 Thessalonians 3.8]- For now we live, if ye stand fast in the Lord. II. Why the Flesh should be Mortified A. Principle 1: That the choicest believers, who are assuredly freed from the condemning power of sin, ought you to make it their business all their days to mortify the indwelling power of sin 

1. Proof texts a. [Colossians 3.1-5]- If ye then be risen with Christ, seek those things which are above, where Christ sitteth on the right hand of God. Set your affection on things above, not on things on the earth. For ye are dead, and your life is hid with Christ in God. When Christ, who is our life, shall appear, then shall ye also appear with him in glory. Mortify therefore your members which are upon the earth; fornication, uncleanness, inordinate affection, evil concupiscence, and covetousness, which is idolatry: 

b. [John 15.2]- Every branch in me that beareth not fruit he taketh away: and every branch that beareth fruit, he purgeth it, that it may bring forth more fruit. 

c. [1 Corinthians 9.27]- But I keep under my body, and bring it into subjection: lest that by any means, when I have preached to others, I myself should be a castaway. 

2. Reasons we ought to make mortification of sins our chief business a. Indwelling sin always abides whilst we are in this world; therefore it is always to be mortified 1.) [Philippians 3.12]- Not as though I had already attained, either were already perfect: but I follow after, if that I may apprehend that for which also I am apprehended of Christ Jesus. 2.) [2 Corinthians 4.16]- For which cause we faint not; but though our outward man perish, yet the inward man is renewed day by day.


2. The work of the Spirit a. He is promised of God to be given unto us to do this work 

1.) [Ezekiel 11.19]- And I will give them one heart, and I will put a new spirit within you; and I will take the stony heart out of their flesh, and will give them an heart of flesh: 

 2.) [Ezekiel 36.26]- A new heart also will I give you, and a new spirit will I put within you: and I will take away the stony heart out of your flesh, and I will give you an heart of flesh. 

 3.) [Isaiah 57.17-18]- For the iniquity of his covetousness was I wroth, and smote him: I hid me, and was wroth, and he went on frowardly in the way of his heart. I have seen his ways, and will heal him: I will lead him also, and restore comforts unto him and to his mourners. 

b. We have all our mortification from the gift of Christ, and all the gifts of Christ are communicated to us and given us by the Spirit of Christ 

1.) [John 15.5]- I am the vine, ye are the branches: He that abideth in me, and I in him, the same bringeth forth much fruit: for without me ye can do nothing. 

 2.) [Acts 5.31]- Him hath God exalted with his right hand to be a Prince and a Saviour, for to give repentance to Israel, and forgiveness of sins. 

 3.) [Acts 2.33]- Therefore being by the right hand of God exalted, and having received of the Father the promise of the Holy Ghost, he hath shed forth this, which ye now see and hear. c. How the Spirit mortifies sin 

1.) By causing our hearts to abound in grace and the fruits that are contrary to the flesh, and the fruits thereof and principles of them a.) [Galatians 5.19-21]- Now the works of the flesh are manifest, which are these; Adultery, fornication, uncleanness, lasciviousness, Idolatry, witchcraft, hatred, variance, emulations, wrath, strife, seditions, heresies, Envyings, murders, drunkenness, revellings, and such like: of the which I tell you before, as I have also told you in time past, that they which do such things shall not inherit the kingdom of God. 

 b.) [Galatians 5.22-25]- But the fruit of the Spirit is love, joy, peace, longsuffering, gentleness, goodness, faith, Meekness, temperance: against such there is no law. And they that are Christ's have crucified the flesh with the affections and lusts. If we live in the Spirit, let us also walk in the Spirit. 

 c.) [Titus 3.5]- Not by works of righteousness which we have done, but according to his mercy he saved us, by the washing of regeneration, and renewing of the Holy Ghost; 

2.) By a real physical efficiency on the root and habit of sin, for the weakening, destroying, and taking it away a.) [Isaiah 4.4]- When the Lord shall have washed away the filth of the daughters of Zion, and shall have purged the blood of Jerusalem from the midst thereof by the spirit of judgment, and by the spirit of burning. 

3.) He brings the cross of Christ into the heart of a sinner by faith, and gives us communion with Christ in his death, and fellowship in his sufferings: of the manner whereof more afterward 

c. The vigour and comfort of our spiritual lives depend much on our mortification, not only as a "causa sine qua non," but as a thing that has an effectual influence there into. 

1.) This alone keeps sin from depriving us of the one and the other. 

a.) It weakens the soul, and deprives it of its strength. 

1.) Proof texts a.) [Psalm 38.3,8]- There is no soundness in my flesh because of thine anger; neither is there any rest in my bones because of my sin. I am feeble and sore broken: I have roared by reason of the disquietness of my heart. b.) [Psalm 40.12]- For innumerable evils have compassed me about: mine iniquities have taken hold upon me, so that I am not able to look up; they are more than the hairs of mine head: therefore my heart faileth me. 

2.) It untunes and unframes the heart itself, by entangling its affections

Consequences and Responses

There are always consequences for trying to live the spiritual life in the flesh. There will be both outward (social) and inward (within the soul) struggles that will often lead to fatigue and ultimate spiritual failure, followed by moral failures and addictions. Some people become spiritual dropouts, while others become floaters, moving from one church to another. Still other people get into a fringe spiritual group that emphasizes fanatical thinking with some opening the door for demonic control. Some people become anger, bitter, depressed, and even suicidal. These will often exhibit antisocial behavior. Other people move into deep self-deception. Some pick up drug, sex, or work addictions to cover their feelings of failure and rejection. Some people even withdraw from society because of the fear of failure. Many will wrestle with anxiety.


Overcoming The Flesh

Since we can not train the flesh, what are to do? First,we are to make no provision for the flesh."But put ye on the Lord Jesus Christ, and make not provision for the flesh, to fulfil the lusts thereof" (Romans 13:14). When we stop to think about it, we plan for most sin. We plan to buy the extra food that we should not eat. We plan to watch the movie that causes us to think lustful thoughts. We plan to say things to hurt others. We plan ways to hurt others who have hurt us. You may ask a friend to come to church. His response may be, "Well, I will have to see about it." What is he saying? He is trying, most likely, to plan a way that he does not have to be in church. "There is a way which seemeth right unto a man, but the end thereof are the ways of death" (Proverbs 14 12). We set ourselves on one road or another. Then we start walking down that road. We may go farther down the road than we thought that we would, but we set ourselves on whichever road we are walking. Remember the words of Paul to Timothy, the young minister, "For bodily exercise profiteth little: but godliness is profitable unto all things, having promise of the life that now is, and of that which is to come." (I Timothy 4:8).

Secondwe are to bring the flesh under subjection. This means that we are to make the flesh a slave to God. Paul wrote to the carnal church of Corinth, "But I keep under my body, and bring it into subjection: lest that by any means, when I have preached to others, I myself should be a castaway" (I Corinthians 9:27). We should see that we are either serving God or we are serving the flesh (self). Jesus therefore said, "No servant can serve two masters: for either he will hate the one, and love the other; or else he will hold to the one, and despise the other. Ye cannot serve God and mammon" (Luke 16:13). We can't walk down two roads at the same time. Furthermore, we, as Believers, don't have to be a slave to sin. "Let not sin therefore reign in your mortal body, that ye should obey it in the lusts thereof. Neither yield ye your members as instruments of unrighteousness unto sin: but yield yourselves unto God, as those that are alive from the dead, and your members as instruments of righteousness unto God. For sin shall not have dominion over you: for ye are not under the law, but under grace. What then? shall we sin, because we are not under the law, but under grace? God forbid. Know ye not, that to whom ye yield yourselves servants to obey, his servants ye are to whom ye obey; whether of sin unto death, or of obedience unto righteousness?" (Romans 6:12-16). The question is, "To whom have I made myself a slave?" We are either a slave to self, the devil, or to God.

It is as if there is an executive board meeting. At that meeting is the flesh that says, "I desire such and such." The mind (intellect) says, "I think such and such." The will says, "I will do it, I can do it, I will not do it, or I just can't do it." The emotions say, "I feel such and such." The Spirit is also there. The Spirit says, "You should do such and such." Now the will is the chairman of the board and can take charge itself (I will) or it can yield to any other party that is there (the flesh, mind, emotions or the Spirit). The will should do this! It should yield to the Spirit. We should say, "Not my will, but Thy will be done." "For it is God which worketh in you both to will and to do of his good pleasure" (Philippians 2:13). We should make our will the servant of the will of God and do His work by His power.

Third, we are to take off the old man and put on the newPaul wrote to the Ephesian church,
"That ye put off concerning the former conversation the old man, which is corrupt according to the deceitful lusts; And be renewed in the spirit of your mind; And that ye put on the new man, which after God is created in righteousness and true holiness" (Ephesians 4:22-24). Have you ever tried to put two coats, the same size, on at the same time? It doesn't work very well. Jesus illustrated the point when he said, "But I say unto you, That whosoever looketh on a woman to lust after her hath committed adultery with her already in his heart. And if thy right eye offend thee, pluck it out, and cast it from thee: for it is profitable for thee that one of thy members should perish, and not that thy whole body should be cast into hell. And if thy right hand offend thee, cut it off, and cast it from thee: for it is profitable for thee that one of thy members should perish, and not that thy whole body should be cast into hell" (Matthew 5:28-30). We must take off the coat of the old man before we put on the coat of the new man in Christ. "A" must come before "B".

Fourthwe are to deny the fleshListen to the words of Jesus. "Then said Jesus unto his disciples, If any man will come after me, let him deny himself, and take up his cross, and follow me. For whosoever will save his life shall lose it: and whosoever will lose his life for my sake shall find it. For what is a man profited, if he shall gain the whole world, and lose his own soul? or what shall a man give in exchange for his soul?" (Matthew 16:24-26). We all know people that have lost control of their mind, will, and emotions. However, if we hold on to self, we lose self. The reason secular psychologists have such a booming business is that they try to help people find themselves. "And when he had called the people unto him with his disciples also, he said unto them, Whosoever will come after me, let him deny himself, and take up his cross, and follow me. For whosoever will save his life shall lose it; but whosoever shall lose his life for my sake and the gospel's, the same shall save it. For what shall it profit a man, if he shall gain the whole world, and lose his own soul? Or what shall a man give in exchange for his soul?" (Mark 8:34-37). We are not to go about trying to find ourselves! First, we are to put self on the shelf. We are to lay it aside. We are to put self behind us. Then, second, we are to take up our cross. This is a picture of dying to self. Then, third, we are free to follow Jesus and should follow him. Steps one and two must come before step three. Otherwise, there will be World War III between self and following after Jesus.

Fifth, we are to mortify the members of the flesh"If ye then be risen with Christ, seek those things which are above, where Christ sitteth on the right hand of God. Set your affection on things above, not on things on the earth. For ye are dead, and your life is hid with Christ in God. When Christ, who is our life, shall appear, then shall ye also appear with him in glory. Mortify therefore your members which are upon the earth; fornication, uncleanness, inordinate affection, evil concupiscence, and covetousness, which is idolatry" (Colossians 3:1-5). We are to focus our attention on what God would have us do, and we are to put to death those things that lead to death. We are not to allow fornication (sex outside of marriage) live in us. We are not to allow burning lust to live within us. We are not to allow our minds to be turned over to evil thoughts. We are not to allow covetousness to remain alive within us. Paul again says, "For if ye live after the flesh, ye shall die: but if ye through the Spirit do mortify the deeds of the body, ye shall live" (Romans 8:13). One way that we put to death the members of the flesh is to focus our attention on what God would have us to do.

Sixthwe are to reckon the flesh crucified. Paul wrote to the performance oriented, Corinthian church, "And they that are Christ's have crucified the flesh with the affections and lusts. If we live in the Spirit, let us also walk in the Spirit" (Galatians 5:24-25). We are to consider it a past experience. When we, as Believers, committed our lives to Jesus, we were spiritually united with Jesus. Therefore, when Jesus died, we died. When Jesus was raised from the dead, we were also raised from the dead. Paul explains, "Knowing this, that our old man is crucified with him, that the body of sin might be destroyed, that henceforth we should not serve sin. For he that is dead is freed from sin. Now if we be dead with Christ, we believe that we shall also live with him: Knowing that Christ being raised from the dead dieth no more; death hath no more dominion over him. For in that he died, he died unto sin once: but in that he liveth, he liveth unto God. Likewise reckon ye also yourselves to be dead indeed unto sin, but alive unto God through Jesus Christ our Lord" (Romans 6:6-11). We should know that we have been crucified! We should understand this, acknowledge this, believe this, and confess this truth. We can see a two sided coin. On one side is our death with Christ, but on the other side is a resurrection to a righteous new life in Him.

Seventhwe are to live an exchanged lifeWe are not to prop up the old man and try to fix the flesh, but we are to exchange our old life for the new life in Christ. "I am crucified with Christ: nevertheless I live; yet not I, but Christ liveth in me: and the life which I now live in the flesh I live by the faith of the Son of God, who loved me, and gave himself for me" (Galatians 2:20). The new life is to replace the old life. Paul further said, "This I say then, Walk in the Spirit, and ye shall not fulfil the lust of the flesh" (Galatians 5:16). Again, we can't be doing two things at the same time. You have see the picture of a little angel sitting on one shoulder and a little demon sitting on the other. When one obeys the one (either the angel or the devil), he will be disobey the other. We are to obey the Spirit so that we will not obey the flesh.

Finally, we need to understand that we must give up everything to follow Jesus. This is the condition for discipleship. Look at the words of Jesus, "If any man come to me, and hate not his father, and mother, and wife, and children, and brethren, and sisters, yea, and his own life also, he cannot be my disciple. And whosoever doth not bear his cross, and come after me, cannot be my disciple" (Luke 14:26-27). We should understand that one can be a born again Believer without being a disciple. The word "disciple" means a "disciplined one". Jesus makes his point clear when he said, "So likewise, whosoever he be of you that forsaketh not all that he hath, he cannot be my disciple." (Luke 14:33). Being a disciple is more than just being a Christian. There may be many Christians, but few disciples. There may be many carnal Believers, but few Believers walk in the Spirit. To be a disciple, we must lay down everything that pertains to our lives. Furthermore, we must be willing to do this every day. Are you willing to do that right now?


Prayer Of Commitment

Please pray the following prayer: Dear Heavenly Father, I realize that I have been trying to live the Christian life in the flesh by my will and my power. I have tried to train my flesh, but have failed. I now realize that I can't train the flesh; therefore: I purpose...
  • to make no provision for the flesh,
  • to bring the flesh under subjection,
  • to take off the old man and put on the new,
  • to deny the flesh,
  • to mortify the members of the flesh,
  • to reckon the flesh crucified,
  • and to live an exchanged life.

Today, I choose by the grace of God to forsake my life and to follow JesusAmen.. Why are we exhorted to mortify sin; seeing the Spirit of God only can do it, let the work be left wholly to him 

1.) It is no otherwise the work of the Spirit but as all graces and good works which are in us are his
