Genesis 22:8

This “wood,” again, Isaac the son of Abraham personally carried for his own sacrifice, when God had enjoined that he should be made a victim to Himself. But, because these had been mysteries which were being kept for perfect fulfilment in the times of Christ, Isaac, on the one hand, with his “wood,” was reserved, the ram being of fered which was caught by the horns in the bramble; Christ, on the other hand, in His times, carried His “wood” on His own shoulders, adhering to the horns of the cross, with a thorny crown encircling His head. …

Let us cleave then to His blessing, and consider what are the means of possessing it. Let us think over the things which have taken place from the beginning. For what reason was our father Abraham blessed? Was it not because he wrought righteousness and truth through faith? Isaac, with perfect confidence, as if knowing what was to happen, cheerfully yielded himself as a sacrifice. Jacob, through reason of his brother, went forth with humility from his own land, and came to Laban and served him; and there was given to him the sceptre of the twelve tribes of Israel.

[7.] Do not then only admire this righteous man, but also imitate him, and when thou seest him amid so great uproar and surge of waves sailing as in a calm, take thou in hand in like way the helm of obedience and fortitude. For look, pray, not only at this that he built up the altar and the wood; but remember too the voice of the lad, and reflect what hosts like snow storms assaulted him to dismay him, when he heard the lad say, “My father, where is the lamb?” Bethink thee how many thoughts were then stirred up armed not with iron, but with darts of flame; and piercing into and cutting him through on every side. …

Why takest thou so many witnesses? Let not thy servant know it, nor, if possible, thy wife. Many are the impediments of the deceitful one. Often she who never before interfered, will impede such works, either from vainglory, or some other motive. Even Abraham, who had an admirable wife, when he was about to offer up his son, concealed it from her, though he knew not what was to happen, but was fully persuaded that he must slaughter his son. What then, would any one that was but an ordinary man have said? Would it not be, “Who is this that perpetrates such acts?” Would he not have accused him of cruelty and brutality? His wife was not even allowed to see her son, to receive his last words, to witness his dying struggles. But he led him away like a captive. …

25. What say you? Are you persuaded, have you been overcome by my words? Or must I use stronger terms in order to persuade you? Yea by the Trinity Itself, Whom you and I alike worship, by our common hope, and for the sake of the unity of this people, grant me this favour; dismiss me with your prayers; let this be the proclamation of my contest; give me my certificate of retirement, as sovereigns do to their soldiers; and, if you will, with a favourable testimony, that I may enjoy the honour of it; if not, just as you please; this will make no difference to me, until God sees what my case really is. What successor then shall we elect? God will provide Himself a shepherd for the office, as He once provided a lamb for a burnt-offering. …
