What Does “Propitiation for Our Sins” Mean?
The short answer
Propitiation is the sacrifice that satisfies God’s righteous judgment against sin, so that God can pardon sinners without ceasing to be just. When 1 John 2:2 calls Jesus “the propitiation for our sins,” it means his death bore the judgment our sins deserved — fully, and in our place.
“And he is the propitiation for our sins: and not for ours only, but also for the sins of the whole world.”
Where Scripture uses the word
The King James Version uses “propitiation” three times, and each sets the same shape: God himself provides the sacrifice that answers his own justice. “And he is the propitiation for our sins: and not for ours only, but also for the sins of the whole world” (1 John 2:2). “Herein is love, not that we loved God, but that he loved us, and sent his Son to be the propitiation for our sins” (1 John 4:10). And Romans 3:25 says God set forth Christ “to be a propitiation through faith in his blood… that he might be just, and the justifier of him which believeth in Jesus.”
The Greek word behind it, hilasmos, is kin to the word for the mercy seat — the gold cover of the ark where atoning blood was sprinkled on the Day of Atonement (Leviticus 16). The picture is that Christ is the true mercy seat, the meeting place of God’s justice and God’s mercy.
How the classic preachers explained it
John Wesley built his most careful definitions of justification on this word. Notice how, for Wesley, propitiation is precisely what lets God forgive righteously:
Propitiation and expiation
The two words are often confused. Expiation is directed at sin — sin is covered, cancelled, removed. Propitiation is directed at God — his righteous judgment is satisfied. Scripture’s use of the mercy-seat language holds both together: the blood covers the sin, and in doing so it answers the judgment. That is why 1 John 4:10 can name propitiation as the very proof of God’s love: the wrath our sins deserved was carried by the Son God himself sent.
“The plain scriptural notion of justification is pardon, the forgiveness of sins. It is that act of God the Father, hereby, for the sake of the propitiation made by the blood of his Son, he “showeth forth his righteousness (or mercy) by the remission of the sins that are past.””
“The covenant of grace doth not require us to do anything at all, as absolutely and indispensably necessary in order to our justification; but only, to believe in Him who, for the sake of his Son, and the propitiation which he hath made, “justifieth the ungodly that worketh not,” and imputes his faith to him for righteousness.”
