Atonement theologically speaks of God's acting in human history to re-establish the original relationship between God and man by dealing with sin. To atone means to make amends--to repair a wrong done. Biblically, it means to remove guilt of man. 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).
Man is a sinner (Rom. 5:8) and cannot atone for himself. Therefore, it was the love of the Father that sent Jesus (1 John 4:10) to die in our place (1 Pet. 3:18) for our sins (1 Pet. 2:24). Because of the atonement, our fellowship with God is restored (Rom. 5:10). (See Reconciliation).
