Nephi so understood it. He consented to go, because his faith told him that when the Lord gives a commandment, he also prepares the way for its fulfillment. The Apostle Paul, in his letter to the Philippians (2:13), expresses this doctrine thus, "For it is God which worketh in you both to will and to do of his good pleasure." There is, therefore, no excuse for disobedience, or for failure.
