Acts 2:38 And Baptism For The Remission Of Sins

Acts 2:38 reads, "Then Peter said unto them, Repent, and be baptized every one of you in the name of Jesus Christ for the remission of sins, and ye shall receive the gift of the Holy Ghost."It should seem clear from this verse that today the "remission (forgiveness) of sins" and the "gift of the Holy Ghost" are contingent upon a person being baptized in water, but many want to argue against this conclusion. Some say "be baptized … for the remission of sins" means because of the remission of sins, meaning a person is baptized because their sins are already forgiven. Admittedly our English word "for" can mean "because of," but the Greek work in this case ("eis") never looks back. The meaning of the Greek word makes it clear that baptism is order to obtain the remission of sins.Aren't those making this argument forgetting that Acts 2:38 also has "repent … for the remission of sins"? If the verse means be baptized because of the remission of sins, then it would also be mean repent because of the remission of sins, meaning a person repents because his sins are already forgiven. Repentance would not be necessary to salvation from sin according to this false theory.Compare Acts 2:38 to Matthew 26:28. They are the same in both the Greek and English in the respect we have been discussing. But nobody believes Jesus shed His blood because our sins were already taken care of first (by another method). No, we all understand that for/eis means "in order to" in Matthew 26:28, and consistency demands that it means the same in Acts 2:38.Doctrine matters (II John verse 9). Baptism is supposed to be done "for the remission of sins." If it is done for another reason, then it wouldn't be scriptural baptism, would it?
