Probably because it serves as a perfect example that baptism it isn't absolutely necessary, regardless of extraordinary efforts to explain it away.
Believe what you will. ;)
Romans 10:10 For it is with your heart that you believe and are justified, and it is with your mouth that you profess your faith and are saved.
You’re are cherry-picking. Let me explain. For some un-Biblical reason many people will pick out verses to live by and completey ignore other scriptures that they don’t like.
The same holds true with salvation. Are you saying that living by Romans 10:10 alone is all that is necessary to be saved? I don’t see any indication here in this verse alone that repentance is required, so can I be save without repenting of my sins?
