GENESIS xv.
Of the nine Divine manifestations made during Abram's life this is the fifth. At Ur, at Kharran, at the oak of Moreh, at the encampment between Bethel and Ai, and now at Mamre, he received guidance and encouragement from God. Different terms are used regarding these manifestations. Sometimes it is said "The Lord appeared unto him;" here for the first time in the course of God's revelation occurs that expression which afterwards became normal, "The word of the Lord came unto Abram." Throughout the subsequent history this word of the Lord continues to come, often at long intervals, but always meeting the occasion and needs of His people and joining itself on to what had already been declared, until at last the Word became flesh and dwelt among us, giving thus to all men assurance of the nearness and profound sympathy of their God. To repeat this revelation is impossible. A repetition of it would be a denial of its reality. For a second life on earth is allowed to no man; and were our Lord to live a second human life it were proof He was no true man, but an anomalous, unaccountable, uninstructive, appearance or simulacrum of a man.
But though these revelations of God are finished, though complete knowledge of God is given in Christ, God comes to the individual still through the Spirit Whose office it is to take of the things of Christ and show them to us. And in doing so the law is observed which we see illustrated here. God comes to a man with further encouragement and light for a new step when he has conscientiously used the light he already has. The temper that "seeks for a sign" and expects that some astounding Providence should be sent to make us religious is by no means obsolete. Many seem to expect that before they act on the knowledge they have, they will receive more. They put off giving themselves to the service of God under some kind of impression that some striking event or much more distinct knowledge is required to give them a decided turn to a religious life. In so doing they invert God's order. It is when we have conscientiously followed such light as we have, and faithfully done all that we know to be right, that God gives us further light. It was immediately on the back of faithful action that Abram received new help to his faith.
The time was seasonable for other reasons. Never did Abram feel more in need of such assurance. He had been successful in his midnight attack and had scattered the force from beyond Euphrates, but he knew the temper of these Eastern monarchs well enough to be aware that there was nothing they hailed with greater pleasure than a pretext for extending their conquests and adding to their territory. To Abram it must have appeared certain that the next campaigning season would see his country invaded and his little encampment swept away by the Eastern host. Most appropriate, therefore, are the words: "Fear not, Abram: I am thy shield."
But another train of thoughts occupied Abram's mind perhaps even more unceasingly at this time. After busy engagement comes dulness; after triumph, flatness and sadness. I have pursued kings, got myself a great name, led captivity captive. Men are speaking of me in Sodom, and finding that in me they have a useful and important ally. But what is all this to my purpose? Am I any nearer my inheritance? I have got all that men might think I needed; they may be unable to understand why now, of all times, I should seem heartless; but, O Lord, Thou knowest how empty these things seem to me, and what wilt Thou give me? Abram could not understand why he was kept so long waiting. The child given when he was a hundred years old might equally have been given twenty-five years before, when he first came to the land of Canaan. All Abram's servants had their children, there was no lack of young men born in his encampment. He could not leave his tent without hearing the shouts of other men's children, and having them cling to his garments--but "to me Thou hast given no seed; and lo! one born in mine house, a slave, is mine heir."
