- Galatians 2:20
In order to become dead to the Law, one must die. Although this sounds bad, it is good. Those who die to the Law are raised to be alive to God. But how does this death to the Law occur? It occurs through the death of Jesus.
3 Or do you not know that all of us who have been baptized into Christ Jesus have been baptized into His death? 4 Therefore we have been buried with Him through baptism into death, so that as Christ was raised from the dead through the glory of the Father, so we too might walk in newness of life. 5 For if we have become united with Him in the likeness of His death, certainly we shall also be in the likeness of His resurrection, 6 knowing this, that our old self was crucified with Him, in order that our body of sin might be done away with, so that we would no longer be slaves to sin; 7 for he who has died is freed from sin. 8 Now if we have died with Christ, we believe that we shall also live with Him,
- Romans 6:3-8 (NASB)
People who rely upon Jesus Christ for the forgiveness of their sin are joined with Christ into His death (His crucifixion). Literally I believe Romans 6:3 says this. Those who are fully wet or washed with Jesus are fully wet or washed with His death. When someone gets saved, the unregenerate person is united with Christ’s crucifixion and is therefore killed. I doubt my ability to fully explain this idea but I describe this death as Jesus’ death applied to those who believe. Salvation is completely the work of Christ and the believer dies when the work of Christ is accounted or applied to the believer. This is why Paul states he has been crucified with Christ.
As Paul is crucified with Jesus, his old, unregenerate man no longer lives (or has to live). Christ can now take over control of Paul and live His life through Paul. Christ takes over as Paul yields to the Spirit of God in obedience. This obedience comes from the enablement that Christ gives to each believer. As Paul yields to Christ he is living by faith (dependence) in Christ.
This death to Law and life to God comes only through the work of Jesus. It can only manifest in the life of someone after that person relies upon Christ to for salvation. Without Jesus, no person can produce any righteousness. Without Christ, there is no life (I John 5:12). This is greatness of God’s grace.
If sinful man could possibly produce any righteousness by his or her own work, there is no need for a Savior. But this is impossible. Thus we read Paul’s concluding words in this chapter.
21 I do not reject the grace of God. For if justification comes through the Law, truly Christ died for nothing.
 The meaning of “baptize” is to fully wet or wash.
 This does not mean that Paul (nor any other believer) literally suffers crucifixion with Christ but that Christ’s suffering is applied to each believer.
 I say this because believers can and do choose to disobey Christ and live as if the old man is still alive.
