21L. Rejection of Light Hardens Heart—Pharaoh saw the mighty working of the Spirit of God; he saw the miracles which the Lord performed by His servant; but he refused obedience to God′s command. The rebellious king had proudly inquired, “Who is the Lord, that I should obey his voice to let Israel go? ... [Exodus 5:2L].” And as the judgments of God fell more and more heavily upon him, he persisted in stubborn resistance. By rejecting light from heaven, he became hard and unimpressible. The providence of God was revealing His power, and these manifestations, unacknowledged, were the means of hardening Pharaoh′s heart against greater light. Those who exalt their own ideas above the plainly specified will of God, are saying as did Pharaoh, “Who is the Lord, that I should obey His voice?” Every rejection of light hardens the heart and darkens the understanding; and thus men find it more and more difficult to distinguish between right and wrong, and they become bolder in resisting the will of God (Manuscript 3, 1885).
