The Problem Atonement Addresses
The English word atonement was coined by William Tyndale as a compound: at-one-ment -- the state of being at one. It captures what the Hebrew kaphar and Greek katalasso both convey: restoration of a broken relationship. Isaiah 59:2 describes the problem precisely: your iniquities have made a separation between you and your God. The entire Old Testament sacrificial system -- daily offerings, the Levitical priesthood, the annual Day of Atonement in Leviticus 16 -- is a divinely instituted provision teaching Israel both the seriousness of sin and the possibility of restored approach. Yet Hebrews 10:4 states plainly that it is impossible for the blood of bulls and goats to take away sins. The animal sacrifices were shadows pointing forward to the substance yet to come.
The Day of Atonement: Israel's Annual Reset
Yom Kippur (Leviticus 16) was the most solemn day in the Israelite calendar. Once a year the high priest entered the Most Holy Place bearing the blood of a bull for his own sins and a goat for the sins of the people, sprinkling that blood on the mercy seat seven times. A second goat -- the scapegoat -- had the high priest lay both hands on its head, confessing all Israel's sins, then was sent into the wilderness: a vivid enactment of sin being carried away. The New Testament reads both images as pointing to Christ: his blood applied in the heavenly sanctuary (Hebrews 9:12) and our sin carried in his own body on the cross (1 Peter 2:24; Isaiah 53:6). The Day of Atonement is not abolished in Christ -- it is fulfilled, permanently and completely.
How Jesus Accomplished Atonement
The New Testament employs a rich array of images to describe the cross. Substitution: Christ bore our sins in his body on the tree (1 Peter 2:24); he was made sin who knew no sin, so that in him we might become the righteousness of God (2 Corinthians 5:21). Propitiation: God put forward Christ as a propitiation by his blood (Romans 3:25) -- the turning aside of divine wrath by an adequate sacrifice. Redemption: you were ransomed with the precious blood of Christ (1 Peter 1:18-19). Reconciliation: God was in Christ reconciling the world to himself, not counting their trespasses against them (2 Corinthians 5:19). Hebrews frames the cross as the ultimate Day of Atonement: Christ entered not into holy places made with hands, but into heaven itself, now to appear in the presence of God on our behalf (Hebrews 9:24). No single image captures the whole; together they paint the full portrait of what the cross accomplished.
Atonement Applied: What Reconciliation Means for Daily Life
Atonement is not merely a past event to be believed -- it is a present reality to be inhabited. Paul's appeal in 2 Corinthians 5:20 is urgent: we implore you on behalf of Christ, be reconciled to God. Three implications follow. First, the believer's access to God is permanent -- the veil of the Temple was torn from top to bottom at Christ's death (Matthew 27:51), permanently removing the barrier between God and humanity. Second, the believer's standing before God is not performance-based -- we stand in grace (Romans 5:2). Third, atonement generates mission: the ministry of reconciliation (2 Corinthians 5:18) is entrusted to the reconciled. Those who have received at-one-ment with God are sent to announce its availability to a world still separated from him.
