I was baptized as a baby into the Roman Catholic church without my knowledge or consent. It was done TO me. But it wasn't until my baptism at a little Southern Baptist church - after I came to the knowledge of the truth of the gospel of the grace of God and received Jesus Christ as my Savior - that it was a genuine baptism into the family of God. This was my outward act of identifying with the death, burial and resurrection of Jesus Christ and that from henceforth I would walk in newness of Life. It was my answer of a good conscience before God of what HE had done within my soul. That really is the ONLY baptism that counts.
So if Hitler walked in and ask to be baptised as an adult right along side you and born again.....would he then go to heaven like you?
Or would you have an issue with that?
Nope...the first one counted just fine and you were freed from original sin at that time...drop dead and go straight to Heaven..
Your second Baptism was merely a reenactment of the first...didn't hurt you, didn't do you any real benefit either...mentally maybe....otherwise nothing.
