Jesus' atonement is declared effective because He takes away the sin of His people completely, as affirmed by multiple scriptures (Hebrews 9:26, Psalm 103:12).
The effectiveness of Jesus' atonement is rooted in the nature of His sacrifice, which is described in Hebrews 9:26 as appearing 'to put away sin by the sacrifice of himself.' Scripture reassures us that this atonement was not only complete but also permanent. For example, Psalm 103:12 states that God removes our sins 'as far as the east is from the west.' This signifies that the atonement made by Jesus is sufficient for all the sin of His elect, as affirmed in 1 John 3:5, where it says He was manifested to take away our sins. Consequently, His sacrifice is recognized as the one and only means through which we can be justified before a holy God.
