Here then was the whole promise and purpose of God in a most precarious position; the land abandoned, the mother of the promised seed in a harem through whose guards no force on earth could penetrate. Abram could do nothing but go helplessly about, thinking what a fool he had been, and wishing himself well back among the parched hills of Bethel. Suddenly there is a panic in the royal household; and Pharaoh is made aware that he was on the brink of what he himself considered a great sin. Besides effecting its immediate purpose, this visitation might have taught Pharaoh that a man cannot safely sin within limits prescribed by himself. He had not intended such evil as he found himself just saved from committing. But had he lived with perfect purity, this liability to fall into transgression, shocking to himself, could not have existed. Many sins of most painful consequence we commit, not of deliberate purpose, but because our previous life has been careless and lacking in moral tone. We are mistaken if we suppose that we can sin within a certain safe circle and never go beyond it.
By this intervention on God's part Abram was saved from the consequences of his own scheme, but he was not saved from the indignant rebuke of the Egyptian monarch. This rebuke indeed did not prevent him from a repetition of the same conduct in another country, conduct which was met with similar indignation: "What have I offended thee, that thou hast brought on me and on my kingdom this great sin? Thou hast done deeds unto me that ought not to be done. What sawest thou that thou hast done this thing?" This rebuke did not seem to sink deeply into the conscience of Abram's descendants, for the Jewish history is full of instances in which leading men do not shrink from man[oe]uvre, deceit and lying. Yet it is impossible to suppose that Abram's conception of God was not vastly enlarged by this incident, and this especially in two particulars.
(1) Abram must have received a new impression regarding God's truth. It would seem that as yet he had no very clear idea of God's holiness. He had the idea of God which Mohammedans entertain, and past which they seem unable to get. He conceived of God as the Supreme Ruler; he had a firm belief in the unity of God and probably a hatred of idolatry and a profound contempt for idolaters. He believed that this Supreme God could always and easily accomplish His will, and that the voice that inwardly guided him was the voice of God. His own character had not yet been deepened and dignified by prolonged intercourse with God and by close observation of His actual ways; and so as yet he knows little of what constitutes the true glory of God.
For learning that truth is an essential attribute of God he could not have gone to a better school than Egypt. His own reliance on God's promise might have been expected to produce in him a high esteem for truth and a clear recognition of its essential place in the Divine character. Apparently it had only partially had this effect. The heathen, therefore, must teach him. Had not Abram seen the look of indignation and injury on the face of Pharaoh, he might have left the land feeling that his scheme had succeeded admirably. But as he went at the head of his vastly increased household, the envy of many who saw his long train of camels and cattle, he would have given up all could he have blotted from his mind's eye the reproachful face of Pharaoh and nipped out this entire episode from his life. He was humbled both by his falseness and his foolishness. He had told a lie, and told it when truth would have served him better. For the very precaution he took in passing off Sarai as his sister was precisely what encouraged Pharaoh to take her, and produced the whole misadventure. It was the heathen monarch who taught the father of the faithful his first lesson in God's holiness.
