Under the simple statement "The Lord said unto Abram, Get thee out of thy country," there are probably hidden years of questioning and meditation. God's revelation of Himself to Abram in all probability did not take the determinate form of articulate command without having passed through many preliminary stages of surmise and doubt and mental conflict. But once assured that God is calling him, Abraham responds quickly and resolutely. The revelation has come to a mind in which it will not be lost. As one of the few theologians who have paid attention to the method of revelation has said: "A Divine revelation does not dispense with a certain character and certain qualities of mind in the person who is the instrument of it. A man who throws off the chains of authority and association must be a man of extraordinary independence and strength of mind, although he does so in obedience to a Divine revelation; because no miracle, no sign or wonder which accompanies a revelation can by its simple stroke force human nature from the innate hold of custom and the adhesion to and fear of established opinion; can enable it to confront the frowns of men, and take up truth opposed to general prejudice, except there is in the man himself, who is the recipient of the revelation, a certain strength of mind and independence which concurs with the Divine intention." That Abraham's faith triumphed over exceptional difficulties and enabled him to do what no other motive would have been strong enough to accomplish, there is therefore no call to assert. During his after-life his faith was severely tried, but the mere abandonment of his country in the hope of gaining a better was the ordinary motive of his day. It was the _ground_ of this hope, the belief in God, which made Abraham's conduct original and fruitful. That sufficient inducement was presented to him is only to say that God is reasonable. There is always sufficient inducement to obey God; because life is reasonable. No man was ever commanded or required to do anything which it was not for his advantage to do. Sin is a mistake. But so weak are we, so liable to be moved by the things present to us and by the desire for immediate gratification, that it never ceases to be wonderful and admirable when a sense of duty enables a man to forego present advantage and to believe that present loss is the needful preliminary of eternal gain.
