Forgiveness of sin
One of the constituent parts of justification. In pardoning sin, God absolves the sinner from the condemnation of the law, and that on account of the work of Christ, i.e., he removes the guilt of sin, or the sinner's actual liability to eternal wrath on account of it. All sins are forgiven freely (Acts 5:31; 13:38; 1 John 1:6-9). The sinner is by this act of grace for ever freed from the guilt and penalty of his sins. This is the peculiar prerogative of God (Psalm 130:4; Mark 2:5). It is offered to all in the gospel. (see JUSTIFICATION.)
