With Abraham it was otherwise. “He went out, not knowing whither he went.”[259] He leaves his father’s house and his father’s gods. He breaks for ever with the past, even before the future has been revealed to him. The thoughts and feelings that had grown up with him from childhood are once for all put away. He has no sheltering ark to receive him. A homeless wanderer, he pitches his tent to-day at the well, not knowing where his invisible guide may bid him stretch the cords on the morrow. His departure from Ur of the Chaldees was a family migration. But the writer of this Epistle, like Philo, describes it as the man’s own personal obedience to a Divine call. Submitting to God’s will, possessed with the inspiration and courage of faith, obeying daily new intimations, he bends his steps this way or that, not knowing whither he goes. True, he went right into the heart of the land of promise. But, even in his own heritage, he became a sojourner, as in a land not his own.[260] God “gave him none inheritance in it, no, not so much as to set his foot on.”[261] Possessor of all in promise, he purchased a sepulchre, which was the first ground he could call his own. The cave of Machpelah was the small beginning of the fulfilment of God’s promise, which the spirit of Abraham is even now receiving in a higher form. It is still the same. The bright dawn of heaven often breaks upon the soul at an open grave. But he journeyed on, and trusted. For a time he and Sarah only; afterwards Isaac with them; at last, when Sarah had been laid to rest, Abraham, Isaac, Jacob, the three together, held on bravely, sojourning with aching hearts, but ever believing. The Apostle brings in the names of Isaac and Jacob, not to describe their faith—this he will do subsequently,—but to show the tenacity and patience of “the friend of God.” His faith, thus sorely tried by God’s long delay, is rewarded, not with an external fulfilment of the promise, but with larger hopes, wider range of vision, greater strength to endure, more vivid realisation of the unseen. “He looked for the city which hath the foundations, whose Architect and Maker is God.”[262] In the promise not a word is said about a city. Apparently he was still to be a nomad chief of a large and wealthy tribe. When God deferred again and again the fulfilment of His promise to give him “this land,” His trusting servant bethought him what the delay could mean. This was his hill of difficulty, where the two ways part. The worldly wisdom of unbelief would argue from God’s tardiness that the reality, when it comes, will fall far short of the promise. Faith, with higher wisdom, makes sure that the delay has a purpose. God intends to give more and better things than He promised, and is making room in the believer’s heart for the greater blessings. Abraham cast about to imagine the better things. He invented a blessing, and, so to speak, inserted it for himself in the promise.
