A belief in one Supreme God, even if at first it was only a henotheistic, and not yet a monotheistic belief, took possession of the leading spirits of the Jewish race at a very early time. All tradition assigns that belief in One God, the Most High, to Abraham. Abraham, though he did not deny the existence of the gods worshipped by the neighbouring tribes, yet looked upon them as different from, and as decidedly inferior to, his own God. His monotheism was, no doubt, narrow. His God was the friend of Abraham, as Abraham was the friend of God. Yet the concept of God formed by Abraham was a concept that could and did grow. Neither Moses, nor the Prophets, nor Christ Himself, nor even Mohammed, had to introduce a new God. Their God was always called the God of Abraham, even when freed from all that was local and narrow in the faith of that patriarch. _Gifford Lectures, II._ To some any attempt to trace back the name and concept of Jehovah to the same hidden sources from which other nations derived their first intimation of deity may seem almost sacrilegious. They forget the difference between the human concept of the Deity and the Deity itself, which is beyond the reach of all human concepts. But the historian reads deeper lessons in the growth of these human concepts, as they spring up everywhere in the minds of men who have been seekers after truth--seeking the Lord if haply they might feel after Him and find Him--and when he can show the slow but healthy growth of the noblest and sublimest thoughts out of small and apparently insignificant beginnings, he rejoices as the labourer rejoices over his golden harvest; nay, he often wonders what is more truly wonderful, the butterfly that soars up to heaven on its silvery wings, or the grub that hides within its mean chrysalis such marvellous possibilities. _Gifford Lectures, II._ The concept of God arises out of necessity in the human mind, and is not, as many theologians will have it, the result of one special disclosure, granted to Jews and Christians only. It seems to me impossible to resist this conviction, where a comparative study of the great religions of the world shows us that the highest attributes which we claim for the Deity are likewise ascribed to it by the Sacred Books of other religions. _Gifford Lectures, II._
