The remission of sins. Mark 1: 4.
When John was in the wilderness he preached the "baptism of repentance for the remission of sins."
Acts 2: 38.
"On the day of Pentecost, many persons were convinced that Jesus was the Christ, and cried out, "Men and brethren, what shall we do?" Peter replied: "Repent, and be baptized every one of you in the name of Jesus Christ, for the remission of sins."
Here we find the inspired Apostle, after Christ's ascension into heaven, teaching that baptism is for the remission of sins.
The case of Paul. Acts 22: 16.
Paul saw a vision in which he was directed to go to a certain place, where it should be told him what to do. He did so, and there fasted and prayed three days. Then the Lord sent to him Ananias, who said, "Arise, and be baptized, and wash away thy sins." Why did not the Lord remit Paul's sins through his fasting and prayer? For the reason that He has instituted baptism for that purpose, and all who desire the blessing of remission of sins must comply with His law.
"Inward grace."
"But," says one, "that doctrine is strange to me; I was always taught that baptism was an outward sign of an inward grace." No such doctrine can be sustained by the Scripture. You must be baptized and have your sins washed away before you are even prepared for the reception of an "inward grace."
"But Peter tells us," urges the objector, "that baptism is 'not the putting away of the filth of the flesh, but the answer of a good conscience towards God.'" And Peter states the truth. Ananias did not tell Paul to be baptized and wash away "the filth of the flesh," but to be baptized and wash away his sins.
