From John Wesley’s sermon “Self-Denial“:
The will of God is a path leading straight to God. The will of man, which once ran parallel with it, is now another path, not only different from it, but in our present state, directly contrary to it: It leads from God. If, therefore, we walk in the one, we must necessarily quit the other. We cannot walk in both. Indeed, a man of faint heart and feeble hands may go in two ways, one after the other. But he cannot walk in two ways at the same time: He cannot, at one and the same time, follow his own will, and follow the will of God: He must choose the one or the other; denying God’s will, to follow his own; or denying himself, to follow the will of God.
