God's amazing Grace!

…even though my conscience accuses me of having grievously sinned
against all of God's commandments and of never having kept any of them,
and even though I am inclined toward all evil, nevertheless, without my
deserving it at all, out of sheer grace, God grants and credits to me the
perfect satisfaction, righteousness, and holiness of Christ, as if I had
never sinned nor been a sinner, as if I had been as perfectly obedient as
Christ was obedient for me. All I need to do is to accept the gift of God
with a believing heart.
