What does the word atonement mean?
God’s holiness and justice require payment for sin. The price was
Jesus’ death; He died in our place. In the Old Testament, God
accepted animal sacrifice as a substitute payment (atonement)
for a person’s sin. These animal sacrifices did not really provide
ultimate forgiveness for sins because the animals were not
valuable enough to replace a man or woman. Rather, they
symbolized Jesus’ future death. Because Jesus is God, He is
perfect and can pay the penalty for another. Because Jesus was
human, He can be the substitute for humankind. “He is the
atoning sacrifice for our sins, and not only for ours but also for the
sins of the whole world” (1 John 2:2).
