Whom God displayed publicly as a propitiation in His blood through faith. -Romans 3:25 NASB
I love what theologian Derek Flood says about this verse and the word propitiation.
So how did the word "propitiation" get into Romans 3:25? The original Greek word is hilasterion. Hilasterion is the Greek rendering of the Hebrew kapporeth which refers to the Mercy Seat of the Arc. Luther in his translation of the Bible renders Hilasterion as "Gnadenstuhl" which is German for Mercy Seat. In context this means that "God has set forth Jesus as the mercy seat (the place where atonement and expiation happen) through faith in his blood". Jesus is thus "the place where we find mercy".Derek explains it further saying:
The idea of propitiation includes that of expiation as its means. We are "made favorable" (propitiation) when our sin is removed (expiation). The problem is not that God is unwilling or unloving (propitiation), but that our sin causes a real break in relationship. As with any relationship, that break must be mended. This is what expiation refers to. Expiation is about cleaning or removing of sin and has no reference to quenching God's righteous anger. The difference is that the object of expiation is sin, not God.Lord we come thanking you for the mending of our relationship to you. We thank you for sending your Son.
Grammatically, one propitiates a person, and one expiates a problem. You cannot expiate (remove) a person or God, nor can one propitiate (make favorable) sin. Christ's death was therefore both an expiation and a propitiation. By expiating (removing the problem of) sin God was made propitious (favorable) to us. Again not because God then suddenly loved us, but because the break in the relationship was mended.
... this devotion is part of an ongoing series on words in the bible.
