Baptism saves you through the resurrection of Jesus:

1 Peter 3:21

21 Corresponding to that, baptism now saves you—not the removal of dirt from the flesh, but an appeal to God for a good conscience—through the resurrection of Jesus Christ,

            Some Christians believe that you must be water baptized in order to be saved. (Remember that we’re assuming that whatever is needed to get to Heaven has or will be done by you.) This verse and the Great Commission that says “whoever believes and is baptized shall be saved” seem to say that you must be water baptized to get to Heaven. But is it talking about the “born again experience”? After all there are three aspects to salvation: spirit, soul, and body. This verse says that baptism saves you … through the resurrection of Jesus Christ. It is the death of Jesus that saves us spiritually. It is His resurrection that ensures we can live the Christian life (He was delivered up because of our transgressions. He was raised up because of our justification.) Let’s leave it there for now.

            When we are born again, all of our sins are forgiven. Our new man didn’t do them. It was our old man. Therefore, our conscience is clear. We wash away the sins of our old man through baptism as it says in Acts. They no longer have a hold on us. The devil can’t come after us condemning us for something we did before we became a Christian. They are forgiven and washed away.

If you could hear God speak to you, I believe this is what He would say:

            "I have washed you, My children. I have set you free from your past. There is nothing that you have done that is too great for what I accomplished at Calvary. There is nothing that cannot be forgiven you when you turn to Me. You are Mine. You are washed in My blood and cleansed as no cleansing agent on earth can accomplish. Trust in Me. Do not listen to Satan as he tries to bring up things of the past. They cannot affect you in My love. You are Mine, and you are washed clean.”

            34. My conscience is clear. Everything my old man did wrong has been forgiven and washed away.
