“That sad and yet blissful hour when Abraham was to take leave of all that was dear to him, when yet once more he was to lift up his head, when his countenance would shine like that of the Lord, when he would concentrate his whole soul in a blessing which was potent to make Isaac blessed all his days–this time would not come! For he would indeed take leave of Isaac, but in such a way that he himself would remain behind; death would separate them, but in such a way that Isaac remained its prey. The old man would not be joyful in death as he laid his hands in blessing upon Isaac, but he would be weary of life as he laid violent hands upon Isaac. And it was God who tried him. Yea, woe, woe unto the messenger who had come before Abraham with such tidings! Who would have ventured to be the emissary of this srrow? But it was God who tried Abraham.
Yet Abraham believed, and believed for this life. Yea, if his faith had been only for a future life, he surely would have cast everything away in order to hasten out of this world to which he did not belong. But Abraham’s faith was not of this sort, if there be such a faith; for really this is not faith but the furthest possibility of faith which has a presentiment of its object at the extremest limit of the horizon, yet is separated from it by a yawning abyss within which despair carries on its game. But Abraham believed precisely for this life, that he was to grow old in the land, honored by the people, blessed in his generation, remembered forever in Isaac, his dearest thing in life, whom he embraced with a love for which it would be a poor expression to say that he loyally fulfilled the father’s duty of loving the son, as indeed is evinced in the words of the summons, “the son whom thou lovest.” Jacob had twelve sons, and one of them he loved; Abraham had only one, the son whom he loved.”
