Why does God not declare himself as the God of Adam? For we know that Abraham sinned even as Adam did. Why then did He not call himself the God of Adam? Why did He not say the God of Abel, the seed of Adam? Why instead did He call himself the God of Abraham, of Isaac, and of Jacob? Why according to the flesh was our Lord Jesus presented in the New Testament as having been born of the seed of Abraham? Why from among all men should God have called himself the God of these three particular persons? Wherein lies the difference between these three and other people? Well, apart from the fact that God had covenanted with these three men, He takes them up as representative personages. He chooses them to represent three types of men in the world. What type of man is Abraham? He is a giant of faith. He is rather uncommon; in fact, he is quite special. As the God of Abraham, God declares himself to be the God of excellent people. Yet, thanks be to God, He is not only the God of the excellent. Were He merely this kind of God, we would sink into despair because we are not persons of excellence. But God is also the God of Isaac. What type of person is Isaac? He is very ordinary. He eats whenever he can, and sleeps as he has opportunity. He is neither a wonder man nor a wicked person. How this fact has comforted many of us! Yet God is not only the God of the ordinary men, He is also the God of the bad men: He is the God of Jacob too, for in the Scriptures Jacob is pictured as one of the worst persons to be found in the Old Testament. Hence through these three persons, God is telling us that He is the God of Abraham the best, the God of Isaac the ordinary, and the God of Jacob the worst. He is the God of those with great faith, He is the God of the common people, and He is also the God of the lowest of men such as thieves and prostitutes. Suppose I am special like Abraham; then He is my God. Suppose I am ordinary like Isaac; then He is also my God. And suppose from my mother's womb I have been bad like Jacob was in that I have striven with my brother; then He is still my God. He has a way with the excellent, with the common, and with the worst of humanity.
