And for then, A.V.; said (in italics) for said, A.V. and T.R.; repent ye for repent, A.V.; unto for for, A.V.; your sins for sins, A.V. Repent, etc. We have in this short verse the summary of Christian doctrine as regards man and God.
Repentance and faith on the part of man; forgiveness of sins, or justification, and the gift of the Holy Ghost, or sanctification, on the part of God. And both these are expressed in the sacrament of baptism, which as it were ties the act of man to the promise of God.
For the sacrament expresses man's faith and repentance on one side, and God's forgiveness and gift on the other.
