Do you not know that all of us who have been baptized into Christ Jesus were baptized into his death? We were buried therefore with him by baptism into death, so that as Christ was raised from the dead by the glory of the Father, we too might walk in newness of life
For if we have been united with him in a death like his, we shall certainly be united with him in a resurrection like his. We know that our former man was crucified with him so that the sinful body might be destroyed, and we might no longer be enslaved to sin.
Romans 6:3-6
At our baptism we become united to Jesus. His life becomes our life. Not only does his life become our life but his death becomes our death. We were buried with him so that we could be raised to new life. This is why at some evangelical churches dunk people in the water when they do adult baptism. The symbol is one of being drowned so that the old you is dead and the new you is raised up and comes out of the water.
So Paul reiterates what he said or works to make it clearer. We have been united to Christ in his death and are united to him in his resurrection. Our former selves have been crucified so that we are no longer slaves to in. Sin is like this organism, this parasite that lives in us and feeds off of us. But once a body is dead the parasite no longer feeds off the body. In the same way since we are new creations in Christ, sin no longer feeds off of us.
We no longer have to be enslaved to the sin of offense because we are new creations in Christ. Take a moment to confess your belief that the old you that held onto offense is dead and that you are a new creation in Christ.
