"For I through the law am dead to the law, that I might live unto God. 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 2:19-20)
One of the greatest doctrinal truths of the Bible is that the Christian life is one of victory over sin. The law of God has condemned us as lawbreakers (James 2:10), but Christ died for our sins, and "ye also are become dead to the law by the body of Christ" (Romans 7:4).
We should live in victory over sin, but somehow we still stumble. "If we say that we have no sin, we deceive ourselves, and the truth is not in us." The remedy for such lapses is at hand, of course. "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).
Nevertheless, if Christ is really living in us by His Spirit, if we have really been born again, then we cannot continue to live in sin. "How shall we, that are dead to sin, live any longer therein?" (Romans 6:2). "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" (vv. 6-7).
The secret to making this doctrine practical reality in our lives is simply the motivation of gratitude. In the words of our text, "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."
We already have the necessary resources: forgiveness, freedom from guilt, eternal life, and the indwelling Spirit of Christ. We must simply avail ourselves of His power, because He loved us and saved us. "Reckon ye also yourselves to be dead indeed unto sin, but alive unto God through Jesus Christ our Lord" (Romans 6:11).
