Jesus took the punishment for our sin upon Himself, as a result freeing us from its inevitable consequence—separation from God. When we receive Jesus Christ as our Lord and Redeemer, a secure union is established with God. And since we have now been joined to Him by means of the indwelling presence of the Holy Spirit, we share in all the benefits that Jesus Himself experienced in His resurrection.(Romans 6:5)

The death and resurrection of Christ as it relates to our own death and life in Him is a constantly recurring theme throughout these chapters of Romans. Time and again he brings this issue to the forefront, because Paul knows that understanding this principle is absolutely vital to our spiritual progress.

At the very heart of this truth is the fact that freedom from the power of sin—our death to sin—is guaranteed by our death to law through Christ’s bodily death and resurrection.(Romans 6:14)

Thinking back to Paul’s example in the first few verses of Romans 7 of a married woman, one might say that Jesus was both the old husband (coming in the form of
sinful flesh, dying for sin to free from law), and the new husband (resurrected
to life in God, never to die again). Freedom is now the absolute reality of our
life in Christ because we are no longer bound by what Paul calls, “the law of sin and death.”(Romans 8:2)
