John Miller in Repentance: A Daring Call to Real Surrender:
What we all desperately need to see is that the love of a holy God is manifested covenantally at the cross. In the sacrifice of the Lamb of God, the Father promises to receive contrite sinners on a daily — no, hourly — basis. The cross says, ‘No matter what your sins, unlimited mercy is available to those who turn to God through Jesus’ merits.’
Having satisfied the demands of His own holy law, the Father must open His mighty arms and embrace every returning son. And he must do it every day. He has promised to do it (Luke 15:11–32, 1 John 1:8–10), and God cannot lie (Heb 6:13–20).
