A NEW CREATURE
“Create in me a clean heart, O God” (Ps 51.10). How is it that David does not say, Reform my heart, heal it, correct it, but create it new? This teaches us a great truth, that the regeneration of a sinner is an actual creation, so admirable that the creation of the universe is the type of it. That creation only cost God a word, but the justification of the sinner cost Jesus Christ all His blood.
Augustine of Hippo
