Psalm 51:6 “Behold, you delight in truth in the inward being, and you teach me wisdom in the secret heart.”
Have you ever gone to a sawmill and watched them process timber? They take a big log out of the woods that may have bumps and knots on it, and they lay it on a cradle, running it through a saw, cutting off one side. Then they bring it back, turn it, and run it through again to cut off another side. When they’re finished, if you stand and look down it, it’s perfectly straight. But if you look at the end of it, the heart is still crooked. That’s the way it is with some individuals who are outwardly living the Christian life. But Jeremiah 17:9 warns the heart is deceitful above all things and desperately wicked. We need regeneration. We must be born again.
