For this cause we also, since the day we heard it, do not cease to pray for you…
The world is in darkness. This is the beginning of a natural day. The sun has not yet risen. Here is a great building. You see it; the sun rises and touches the top of it; gradually it touches the highest ridges and windows; then it comes down, and touches another story, and another, till at last the light, in all its fulness and amplitude, fills the whole house and bathes the whole building in the splendour of its rays. Every room — from the lowest to the highest — all filled! Now, that gives you a faint idea of what the apostle means. The knowledge of God fills, not one faculty alone, not the intellect looking at truth objectively, but the whole nature; feeling, imagination, sensibility, all flooded with this Divine light.
