In the mean while...
We are all born with a fallen nature.
Thus?
Born in sin.
Jesus got rid of the consequences for sin, in our place, on the Cross.
You waste your time. He has been shown many times it is the new covenant where the blood of the Lamb remits sin but he keeps on insisting it can only happen in the water. He would rather believe what fallible Peter says rather than what his Lord says.
Matthew 26:28
For this is My blood of the new covenant, which is shed for many for the remission of sins.
