What was that call, coupled with such a magnificent and cheering promise? It was the voice of God commanding Abram to leave country and kindred and go to a country utterly unknown to him, not even indicated to him, but which in due time should be revealed to him. He is not called to repudiate idolatry, but by divine command to go to an unknown country. He must have been already a believer in the One Supreme God, or he would not have felt the command to be imperative. Unless his belief had been monotheistic, we must attribute to him a marvellous genius and striking originality of mind, together with an independence of character still more remarkable; for it requires not only original genius to soar beyond popular superstitions, but also great force of will and lofty intrepidity to break away from them,--as when Buddha renounced Brahmanism, or Socrates ridiculed the Sophists of Attica. Nothing requires more moral courage than the renunciation of a popular and generally received religious belief. It was a hard struggle for Luther to give up the ideas of the Middle Ages in reference to self-expiation. It is exceedingly rare for any one to be emancipated from the tyranny of prevailing dogmas. So, if Abram was not divinely instructed in a way that implies supernatural illumination, he must have been the most remarkable sage of all antiquity to found a religion never abrogated by succeeding revelations, which has lasted from his time to ours, and is to-day embraced by so large a part of the human race, including Christians, Mohammedans, and Jews. Abram must have been more gifted than the whole school of Ionian philosophers united, from Thales downward, since after three hundred years of speculation and lofty inquiries they only arrived at the truth that the being who controls the universe must be intelligent. Even Socrates, Plato, and Cicero--the most gifted men of classical antiquity--had very indefinite notions of the unity and personality of God, while Abram distinctly recognized this great truth even amid universal idolatry and a degrading polytheism. Yet the Bible recognizes in Abram moral rather than intellectual greatness. He was distinguished for his faith, and a faith so exalted and pure that it was accounted unto him for righteousness. His faith in God was so profound that it was followed by unhesitating obedience to God's commands. He was ready to go wherever he was sent, instantly, without conditions or remonstrance. In obedience to the divine voice then, Abram, after the death of his father Terah, passed through the land of Canaan unto Sichem, or Shechem, afterward a city of Samaria. He then went still farther south, and pitched his tent on a mountain having Bethel on the west and Hai on the east, and there he built an altar unto the Lord. After this it would appear that he proceeded still farther to the south, probably near the northern part of Idumaea.
