I’m saying, like Peter did in the first gospel sermon, that baptism of a penitent believer, not a Christian, is for the remission of sins. I don’t think that means if he’s not baptized, he still has the remission of his sins.
What do you believe?
Since baptism puts one into Christ, I think that means if he’s not baptized, he’s not in Christ. Do you think that means he’s saved outside of Christ?
Please tell me what you believe.
We have to get our terminology down first.
A believer, baptized or not, is a Christian.
Regarding baptism putting us in Christ, I think you've read the verses out of context.
When we place our faith in Christ, that is we believe Him, we repent and our sins are forgiven at that moment. We receive the Holy Spirit. We are sealed by the Spirit.
Baptism is the outward sign of what has happened inside the believer.
Again, I go back to the example of the thief on the cross. He wasn't able to be baptized yet he professed his belief in Christ and He told him he would be with Him in Paradise. I understand that as the thief's sins were forgiven and he would be with Christ in Paradise.
