In Sermon 61, St. Augustine references Luke 11:12 and other passages to show that, even when we are wicked, the Father still loves us and is good to us.
Sermon 61, 1-2:
“A wonderful thing, brothers! We may be evil, but we have a good Father.
“…Therefore, brothers, since we evil ones have a good father, let us not remain evil forever.
“Nobody evil does good. If nobody evil does good, how can an evil person do good to himself?
“The One Who is always good makes good out of evil… We know He gives His children good things ‘according to the time’ (Rom. 9:9): good temporal things, good bodily things, good carnal things, even when we may be evil.
“And what are these good things, if you doubt them?
“Fish. Eggs. Bread. Fruit. Grain. This light, this air. These things which we observe — they are good.
“Men are celebrated for such riches, and they do not recognize other men as their equals in such things — in things, I say, for which men are celebrated — loving flashy clothing, rather than considering the same skin that’s underneath.
“These riches are good things, all the same. But all these good things which I have mentioned, they can be owned by either good people or evil.”
