This is a symbol of baptism, which now saves you-- not the putting away of the filth of the flesh, but the answer of a good conscience toward God, through the resurrection of Jesus Christ,
Once again in Acts 2:38, Peter says, "Repent and be baptized everyone of you in the name of Jesus Christ for the remission of sins...." Is it not evident that baptism stands between the sinner and the remission of his sins? Correct teaching results in correct baptism. To reason that God will accept any other baptism than that which is "for" or "in order to" the remission of sins is to argue that He will accept a baptism that He has not commanded, one that He has not authorized.
