Let no man think that the fear of damnation will bring him to the mercy-seat at last, if the burden and gloom of being “condemned already” cannot now bend his will. “Even as they refused to have God in their knowledge, God gave them up unto a reprobate mind” (Rom. i. 28). “I gave them My statutes and showed them My judgments, which if a man do, he shall even live in them.... I gave them statutes that were not good, and judgments wherein they should not live” (Ezek. xx. 11, 25). This is the inevitable law, the law of a confused and darkened judgment, a heart made heavy and ears shut, a conscience seared, an infatuated will kicking against the pricks, and heaping to itself wrath against the day of wrath. Wilful sin is always a challenge to God, and it is avenged by the obscuring of the lamp of God in the soul. Now, a part of His guiding light is prudence; and it is possible that men who will not be warned by the fear of injury to their conscience, such as they suppose that Pharaoh suffered, may be sobered by the danger of such derangement of their intellectual efficiency as really befel him. In this sense men are, at last, impelled blindly to their fate (and this is a judicial act of God, although it comes in the course of nature), but first they launch themselves upon the slope which grows steeper at every downward step, until arrest is impossible. On the other hand, every act of obedience helps to release the will from its entanglement, and to clear the judgment which has grown dull, anointing the eyes with eye-salve that they may see. Not in vain is the assertion of the bondage of the sinner and the glorious liberty of the children of God. A second time, then, Moses presented himself before Pharaoh with his demands; and, as he had been forewarned, he was now challenged to give a sign in proof of his commission from a god. And the demand was treated as reasonable; a sign was given, and a menacing one. The peaceable rod of the shepherd, a fit symbol of the meek man who bore it, became a serpent[10] before the king, as Moses was to become destructive to his realm. But when the wise men of Egypt and the enchanters were called, they did likewise; and although a marvel was added which incontestably declared the superior power of the Deity Whom Aaron represented, yet their rivalry sufficed to make strong the heart of Pharaoh, and he would not let the people go. The issue was now knit: the result would be more signal than if the quarrel were decided at one blow, and upon all the gods of Egypt the Lord would exercise vengeance.
