Romans 7:12-20 (ESV)
12 So the law is holy, and the commandment is holy and righteous and good.
13 Did that which is good, then, bring death to me? By no means! It was sin, producing death in me through what is good, in order that sin might be shown to be sin, and through the commandment might become sinful beyond measure. 14 For we know that the law is spiritual, but I am of the flesh, sold under sin. 15 For I do not understand my own actions. For I do not do what I want, but I do the very thing I hate. 16 Now if I do what I do not want, I agree with the law, that it is good. 17 So now it is no longer I who do it, but sin that dwells within me. 18 For I know that nothing good dwells in me, that is, in my flesh. For I have the desire to do what is right, but not the ability to carry it out. 19 For I do not do the good I want, but the evil I do not want is what I keep on doing. 20 Now if I do what I do not want, it is no longer I who do it, but sin that dwells within me.
Easton’s Bible Dictionary defines the Moral Law as the revealed will of God as to human conduct, binding on all men to the end of time. It is perfect, perpetual, holy, good, spiritual, and exceedingly broad.
However, left to our own natural tendencies and our own ability, we, in and of ourselves, cannot keep it. We will always sin, making choices that are not good for us. Whether we are a new Christian or have been a Christian for a long time, we all struggle with sin because we are of the flesh and have a sinful nature. This doesn’t excuse our sin, but makes us realize that we are, indeed, sinful.
So, what are we to do?
We are to adopt the discipline of confession and repentance, laying our sin at the foot of the cross and receiving God’s forgiveness. John tells us: If we say we have no sin, we deceived ourselves, and the truth is not in us. If we confess our sins, he is faithful and just to forgive us our sins and to cleanse us from all unrighteousness (1 John 1:8-9).
Though we are sinful, we are saved, not by the law, but by the blood of Christ shed at Calvary. It is by the power of the Holy Spirit – not our own power or ability – that we are able to refrain from sin as He transforms us from one degree of glory to another (2 Corinthians 3:18).
Now to him who is able to keep you from stumbling and to present you blameless before the presence of his glory with great joy, to the only God, our Savior, through Jesus Christ our Lord, be glory, majesty, dominion, and authority, before all time and now and forever. Amen. (Jude 1:24-25)
