HOW TO DO THE “WHAT TO DO”
Have you ever known what you ought to do, desired to do it, and yet found yourself unable to actually carry it out? You know the right thing. You want to do the right thing. You may even determine in your heart that you are going to do the right thing, but somehow the doing of it seems to escape you. The Apostle Paul knew this struggle well. He said in Romans 7:18, “For I know that in me (that is, in my flesh,) dwelleth no good thing: for to will is present with me; but how to perform that which is good I find not.” There it is: the will was present, but the ability to perform was lacking. Paul knew the “what to do,” but he could not find the “how to do.” The struggle: “For that which I do I allow not: for what I would, that do I not; but what I hate, that do I,” Romans 7:15. Paul was saved, but lived a miserable Christian experience at this time.
This is where many people become frustrated in their walk with God. We know we should love, forgive, endure, pray, overcome temptation, walk in holiness, speak graciously, and live according to the Word of God. We know what God has called us to do, but the question remains, How do I actually do it? Our natural response is to try harder. We make up our minds that we will do better. We determine that this time we will overcome. But sooner or later we discover what Paul discovered: the flesh cannot produce the life that God requires. The problem is not that God's standard is too high. The problem is that we cannot produce God's life through human strength. For if righteousness could come by anything you do, then Christ is dead in vain (Gal.2:21).
To understand how Christ becomes the answer to our “how,” we have to understand the Cross. Calvary was not merely the place where Jesus paid the penalty for the sins we had committed. It was the place where God dealt with the whole problem of sin and our confidence in ourselves. Paul tells us in Colossians 2:9, “For in him dwelleth all the fulness of the Godhead bodily.” Everything that God is dwells in Christ. Then he says in verse 10, “And ye are complete in him.” Think about that. We are complete in Him. Our completeness is not found in how well we perform, how strong our flesh becomes, or how much religious effort we can produce. Our completeness is found in Christ.
Paul continues in Colossians 2:11-12, speaking of being “circumcised with the circumcision made without hands,” being “buried with him in baptism,” and being “risen with him through the faith of the operation of God, who hath raised him from the dead.” Something happened to us in our union with Christ. We were not simply given a better set of instructions. We were brought into a new position in Christ. Then Paul says, “And you, being dead in your sins and the uncircumcision of your flesh, hath he quickened together with him, having forgiven you all trespasses” (Colossians 2:13). The guilt was dealt with. The debt was dealt with. “Blotting out the handwriting of ordinances that was against us, which was contrary to us, and took it out of the way, nailing it to his cross” (Colossians 2:14).
But the Cross did not stop there. Colossians 2:15 says, “And having spoiled principalities and powers, he made a shew of them openly, triumphing over them in it.” The Cross was not Christ's defeat. The Cross was His triumph. Sin's penalty was dealt with, the handwriting against us was nailed to His Cross, and Christ triumphed over the powers of darkness.
Yet there is another part of the Cross that we must understand if we are ever going to stop trying to live the Christian life in our own strength. The Cross dealt not only with what we have done, but with who we were in Adam. It dealt with our old man, our old position, and our confidence in the flesh. Paul said in Galatians 2:20, “I am crucified with Christ: nevertheless I live; yet not I, but Christ liveth in me.” This is the mystery of the Christian life. I am crucified with Christ, yet I live. But the life I now live is not supposed to be produced by me. “Christ liveth in me.”
Romans 6:6 says, “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.” And Romans 6:11 tells us, “Likewise reckon ye also yourselves to be dead indeed unto sin, but alive unto God through Jesus Christ our Lord.” The word “reckon” is important. God is calling us to believe what He says about the work He has already accomplished. Faith does not attempt to crucify what God says has already been crucified. Faith takes God at His Word and rests upon His finished work.
This is why understanding our position in Christ is so important. If I continually look at myself, I will continually measure my ability, my failures, my weaknesses, and my performance. Then sin revives and I die (Rom.7:9). But faith looks away from self and looks unto Christ. The Cross tells me that I cannot save myself, and it also tells me that I cannot sanctify myself by the strength of my flesh. The same Christ who is my salvation is also my life. The same grace that brought me to Christ is the grace by which I must continue to walk. “As ye have therefore received Christ Jesus the Lord, [so] walk ye in him:” Colossians 2:6.
Paul brings us out of the struggle of Romans 7 and into the glorious liberty of Romans 8. He says, “For the law of the Spirit of life in Christ Jesus hath made me free from the law of sin and death,” Romans 8:2. Notice that he calls it a law. There is the law of sin and death, but there is also a greater law: “the law of the Spirit of life in Christ Jesus.” We do not overcome the law of sin and death by merely determining to try harder. We overcome by the operation of another life and another power. The Holy Spirit applies the finished work of Christ to us as we believe and walk by faith.
The Christian life, then, is not simply God saying, “Here is what I want you to do. Now go do it.” Philippians 2:13 says, “For it is God which worketh in you both to will and to do of his good pleasure.” Isn't that the answer to Romans 7:18? Paul said, “to will is present with me; but how to perform that which is good I find not.” But Philippians tells us, “It is God which worketh in you both to will and to do.” God works in us not only to will His good pleasure, but to do His good pleasure.
That does not make us passive. It makes us dependent. We still obey. We still yield. We still walk. We still believe. But we no longer place our confidence in the flesh. We recognize that apart from Christ we can do nothing. Jesus said in 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.” The branch does not struggle to manufacture fruit. The branch abides in the vine, and the life of the vine produces the fruit.
So how do we do the “what to do”? We do it by faith in the One who has already finished the work. We look to the Cross. We believe what God says about our position in Christ. We reckon ourselves dead indeed unto sin, but alive unto God through Jesus Christ our Lord. We cease trusting in the strength of the flesh and learn to depend upon the Spirit of life in Christ Jesus. We abide in Him, and we trust Him to work in us both to will and to do of His good pleasure- that’s grace!
The answer is not found in trying harder to become what God wants us to be. The answer is found in trusting more fully in what Christ has already accomplished and in allowing His life to be expressed through us. We cannot do God's work by our own strength any more than we could save ourselves by our own righteousness. Salvation is by grace through faith, and the Christian life is also lived by faith. As Paul said, “The life which I now live in the flesh I live by the faith of the Son of God” (Galatians 2:20).
Perhaps that is why Paul's cry in Romans 7 ends not in despair but in thanksgiving. After asking, “Who shall deliver me?” he answers, “I thank God through Jesus Christ our Lord.” The man who could not find how to perform had finally discovered that the answer was never in himself. It was Christ.
And that is the answer for us today. When you know the “what to do” but cannot find the “how to do,” look to Jesus. Look to Calvary. Rest your faith in the finished work of Christ. Remember that you are “complete in him.” Remember that your old man was crucified with Him. Remember the law of the Spirit of life in Christ Jesus! How He operates within the life of a believer! Remember that “it is God which worketh in you both to will and to do of his good pleasure.”
You do not need to manufacture the life of Christ. You need to trust the Christ who is your life. And when you discover that the answer is not “me trying to do for God,” but Christ working in me, you can say with Paul:
“I thank God through Jesus Christ our Lord.”
For “the just shall live by faith.”
