The justification of a sinner is instantaneous and complete. . . . It is an all-comprehending act of God. All the sins of a believer, past, present, and future, are pardoned when he is justified. The sum-total of his sin, all of which is before the Divine eye at the instant when God pronounces him a justified person, is blotted out or covered over by one act of God. Consequently, there is no repetition in the Divine mind of the act of justification; as there is no repetition of the atoning death of Christ, upon which it rests.
