To atone means to make amends, to repair a wrong done. Biblically, it means to remove sin. The Old Testament atonements offered by the high priest were temporary and a foreshadow of the real and final atonement made by Jesus. Jesus atoned for the sins of the world (1 John 2:2). This atonement is received by faith (Rom. 5:1; Eph. 2:8-9).
