The purpose of God's present appearance to Abram was to renew the covenant, and this He does in terms so explicit, so pregnant, so magnificent that Abram must have seen more distinctly than ever that he was called to play a very special part in God's providence. That kings should spring from him, a mere pastoral nomad in an alien country, could not suggest itself to Abram as a likely thing to happen. Indeed, though a line of kings or two lines of kings did spring from him through Isaac, the terms of the prediction seem scarcely exhausted by that fulfilment. And accordingly Paul without hesitation or reserve transfers this prediction to a spiritual region, and is at pains to show that the many nations of whom Abram was to be the father, were not those who inherited his blood, his natural appearance, his language and earthly inheritance, but those who inherited his spiritual qualities and the heritage in God to which his faith gave him entrance. And he argues that no difference of race or disadvantages of worldly position can prevent any man from serving himself heir to Abram, because the seed, to whom as well as to Abram the promise was made, was Christ, and in Christ there is neither Jew nor Gentile, bond nor free, but all are one. In connection then with this covenant in which God promised that He would be a God to Abram and to his seed, two points of interest to us emerge. First that Christ is Abram's heir. In His use of God's promise we see its full significance. In His life-long appropriation of God we see what God meant when He said, "I will be a God to thee and to thy seed." We find our Lord from the first living as one who felt His life encompassed by God, embraced and comprehended in that higher life which God lives through all and in all. His life was all and whole a life in God. He recognised what it is to have a God, one Whose will is supreme and unerringly good, Whose love is constant and eternal, Who is the first and the last, beyond Whom and from under Whom we can never pass. He moved about in the world in so perfectly harmonious a correspondence with God, so merging Himself in God and His purpose and with so unhesitating a reliance upon Him, that He seemed and was but a manifestation of God, God's will embodied, God's child, God expressing Himself in human nature. He showed us once for all the blessedness of true dependence, fidelity and faith. He showed us how that simple promise 'I will be a God to thee,' received in faith, lifts the human life into fellowship with all that is hopeful and inspiring, with all that is purifying, with all that is real and abiding.
