The phrase "to the remission of sins" is not the same as "because of the remission of sins", and you know that. It is the idea of movign towards something, not looking back. It is the same grammatical construct as in Matthew 26:28, and yet you wish to have it translated completely opposite. Try again.
Maybe you should spend a little time looking at the Greek. It doesn't say what you want it to say. Again, you are trying to make another requirement for salvation other than grace through faith in Christ. You are adding to the Gospel. Baptism is not what remits your sins. The Atonement is for the remission of sins.
Baptism is a sacrament instituted by Christ to demonstrate God's Grace, the same as the Lord's Supper. But neither the Lord's Supper or Baptism saves you, nor does Baptism perform the actual taking away of sins. Try as you will to dance around it, that's what you're saying. To say that Baptism is FOR the remission of sins, you are saying that Baptism is what actually remits the sins. It is the Atonement of Christ for you which takes away your sins, when you believe.
You are saying that a man may believe on Christ, but is still in his sins until he is Baptised. Then you throw in the Dispensational dodge to get around the obvious contradiction presented by the Thief on the Cross. Your theology is a pretzel, it's so twisted.
