But Abraham had faith and steadfastly lived in hope. Had Abraham been less firm in his trust, then would he have given up that hope. He would have said to God: "So it is, perchance, not Thy will, after all, that this shall come to pass. I shall surrender my hope. It was my only one, it was my bliss. I am sincere, I conceal no secret grudge for that Thou didst deny it to me." He would not have remained forgotten, his example would have saved many a one; but he would not have become the Father of Faith. For it is great to surrender one's hope, but greater still to abide by it steadfastly after having surrendered it; for it is great to seize hold of the eternal hope, but greater still to abide steadfastly by one's worldly hopes after having surrendered them. Then came the fulness of time. If Abraham had not had faith, then Sarah would probably have died of sorrow, and Abraham, dulled by his grief, would not have understood the fulfillment, but would have smiled about it as a dream of his youth. But Abraham had faith, and therefore he remained young; for he who always hopes for the best, him life will deceive, and he will grow old; and he who is always prepared for the worst, he will soon age; but he who has faith, he will preserve eternal youth. Praise, therefore, be to this story! For Sarah, though advanced in age, was young enough to wish for the pleasures of a mother, and Abraham, though grey of hair, was young enough to wish to become a father. In a superficial sense it may be considered miraculous that what they wished for came to pass, but in a deeper sense the miracle of faith is to be seen in Abraham's and Sarah's being young enough to wish, and their faith having preserved their wish and therewith their youth. The promise he had received was fulfilled, and he accepted it in faith, and it came to pass according to the promise and his faith; whereas Moses smote the rock with his staff but believed not. There was joy in Abraham's house when Sarah celebrated the day of her Golden Wedding. But it was not to remain thus; for once more was Abraham to be tempted. He had struggled with that cunning power to which nothing is impossible, with that ever watchful enemy who never sleeps, with that old man who outlives all--he had struggled with Time and had preserved his faith. And now all the terror of that fight was concentrated in one moment. "And God tempted Abraham, saying to him: take now thine only son Isaac, whom thou lovest, and get thee into the land of Moriah; and offer him there for a burnt offering upon one of the mountains which I will tell thee off.[2]"
