A quote

"It may be, that during a sermon two men are listening to the same truth; one of them hears as attentively as the other, and remembers as much of it; the other is melted to tears or moved with solemn thoughts; but the one though equally attentive, sees nothing in the sermon, except, may be, certain important truths well set forth; as for the other, his heart is broken within him and his soul is melted. Ask me how it is that the same truth has an effect upon this one, and not upon the other: because the mysterious Spirit of the living God goes with the truth to one heart and not to the other."
-Spurgeon
