Thomas Manton, Works VI, p. 117:
We are apt to abuse our knowledge. Saving knowledge makes us more humble, but carnal knowledge more proud. Where it is in gift rather than in grace, there men are puffed up. The more we know God or ourselves by a divine light, the more humble we shall be. “When I was instructed, I smote upon my thigh; I was ashamed, even confounded, because I did bear the reproach of my youth,” (Jer. 31.18, 19). The more light we have from God, the more we look into a vile heart. When Adam’s eyes are opened, he runs into the bushes; he was ashamed. So when God opens the eyes, and teacheth a Christian, this makes him more humble.
