But then God called Abraham to do a strange and terrible thing. He was to go and take his dear son Isaac to the top of a hill, and there to offer him up to God as if he had been a calf or a lamb. Of course, in general, to do such a thing would be shockingly wicked; but Abraham knew that when God commanded a thing, it must be right to do as he was bidden, however dreadful it was to him.

So they set out together. Abraham took the knife, and a vessel with fire in it and Isaac carried the wood with which the sacrifice was to be burnt. On the way Isaac said, "My father, behold the fire and the wood: but where is the lamb for a burnt offering?" And Abraham answered, "My son, God will provide Himself a lamb for a burnt offering."

ABRAHAM OFFERING ISAAC AS A SACRIFICE.—Gen. 22:11, 12.

Isaac soon knew he was to be the lamb, for his father put the wood in order, and bound his limbs, and took the knife. And Isaac did not complain or struggle. He was ready, like his father, to do the will of God. But just as Abraham had the knife ready to slay his son, an angel called to him out of Heaven: "Lay not thine hand upon the lad, neither do thou anything unto him: for now I know that thou fearest God, seeing thou hast not withheld thy son, thine only son from Me."

REBEKAH SEES ISAAC COMING TO MEET HER.—Gen. 24:64, 65.

Then Abraham unbound his son, and was glad as if Isaac had really risen from the dead. And he saw a ram caught in the thicket by its horns; so he took that, and offered it up instead of Isaac. Thus God really provided a lamb for a burnt offering.
