--1 John 4:10
This is incomparable love and immeasurable love, God giving his Son as a sacrifice to cover the sins of those who had treated him with rejection and contempt. It is a love as old as God himself, and as free.-Donald Macleod, Christ Crucified: Understanding the Atonement (IVP, 2014), 128
Yet in its impulse toward forgiveness it does not set aside the need for sin to be expiated. Deep in the nature of God himself there is a necessity for a hilasmos.
But God not only requires it. He provides it; and he not only provides it, he becomes it.
