What happened to Barabbas is a picture of what happens when a person is born again. Barabbas was guilty; Jesus was innocent. Yet Jesus suffered the death that Barabbas should have experienced, and Barabbas went free.

Likewise, we were all guilty (Rom. 3:23) and condemned to death (Rom. 6:23), yet Jesus suffered our punishment so that we may go free (2 Cor. 5:21). Just as Barabbas didn't ask for this substitution, so "God commended his love toward us, in that, while we were yet sinners, Christ died for us" (Rom. 5:8).

Barabbas was freed, but he had to choose whether or not to accept this new start and remain free, or go back to his old ways and come under the judgment of Rome again. Likewise, we have all been freed through the substitutionary death of Jesus, but we have to choose whether to accept our freedom by putting faith in Jesus or to reject it, by denying Him.

Our death to sin and resurrection to life with Christ, is already a reality in our spirits but will only become a physical reality when we know and believe it. In the same way that Jesus died unto sin once, and death no longer has dominion over Him, the person who recognizes their death with Christ unto sin, will not allow sin to rule over him anymore. Any Christian who is struggling with sin has not recognized that they are dead unto sin.
