"God himself will provide the lamb for the burnt offering, my son." (Genesis 22:8)
God tests Abraham. Take your son, your only son, whom you love, Isaac, and go to the region of Moriah. Sacrifice him there as a burnt offering. The command is precise, accumulating the weight of the relationship: son, only son, the one you love, Isaac. It is asking for everything. Abraham rises early in the morning. He does not argue, does not negotiate. He saddles his donkey, splits wood for the burnt offering, and sets out with Isaac and two servants.
On the third day he sees the place. He tells the servants to wait: we will worship and then we will come back to you. The Letter to the Hebrews says Abraham reasoned that God could even raise the dead, and so in a manner of speaking he did receive Isaac back from death (Hebrews 11:19). When Isaac asks where the lamb for the burnt offering is, Abraham answers: God himself will provide the lamb for the burnt offering, my son. He binds Isaac on the altar. He raises the knife. The angel of the LORD calls out: do not lay a hand on the boy. Now I know that you fear God, because you have not withheld from me your son, your only son.
Abraham looks up and sees a ram caught in the thicket. He calls the place The LORD Will Provide. The Catechism identifies the offering of Isaac as the supreme typological prefiguration of the sacrifice of Christ: the beloved son, the wood carried to the mountain, the three days, the provision of the substitutionary lamb. What Abraham was spared doing, the Father accomplished on Calvary (CCC 2572).
Brothers and sisters, God himself will provide. Abraham said it as a statement of trust before he knew how it would be fulfilled. The ram in the thicket was not yet visible when the words were spoken. Say it in faith before the provision appears. Whatever is bound on your altar today, whatever God has asked you to surrender, trust the God who provides before you can see the ram in the thicket.
Lord God, you provided the ram for Abraham and you provided your own Son for us. Give us Abraham's willingness to hold nothing back from you, trusting that you will provide on the mountain. On the mount of the LORD it will be provided. Through Christ our Lord. Amen.
