Jesus reveals Himself throughout the Bible…even in the Old Testament. The Old Testament points us to Christ. Throughout the OT, God shows that we are sinners. He also shows that He loves us and provides a sacrifice for our sins, a way to eternal life. He shows us that He desires our heart. He is a God of mercy and love. The covenant He made with Abraham goes far beyond His Chosen People, the Israelites. He will bless all the nations through His Son, who would be the Lamb of sacrifice for us.
Now it came to pass after these things that God tested Abraham, and said to him, “Abraham!”
And he said, “Here I am.”
Then He said, “Take now your son, your only son Isaac, whom you love, and go to the land of Moriah, and offer him there as a burnt offering on one of the mountains of which I shall tell you.”
So Abraham rose early in the morning and saddled his donkey, and took two of his young men with him, and Isaac his son; and he split the wood for the burnt offering, and arose and went to the place of which God had told him. Then on the third day Abraham lifted his eyes and saw the place afar off. And Abraham said to his young men, “Stay here with the donkey; the lad and I will go yonder and worship, and we will come back to you.”
So Abraham took the wood of the burnt offering and laid it on Isaac his son; and he took the fire in his hand, and a knife, and the two of them went together. But Isaac spoke to Abraham his father and said, “My father!”
And he said, “Here I am, my son.”
Then he said, “Look, the fire and the wood, but where is the lamb for a burnt offering?”
And Abraham said, “My son, God will provide for Himself the lamb for a burnt offering.” So the two of them went together.
Then they came to the place of which God had told him. And Abraham built an altar there and placed the wood in order; and he bound Isaac his son and laid him on the altar, upon the wood. And Abraham stretched out his hand and took the knife to slay his son.
But the Angel of the Lord called to him from heaven and said, “Abraham, Abraham!”
So he said, “Here I am.”
And He said, “Do not lay your hand on the lad, or do anything to him; for now I know that you fear God, since you have not withheld your son, your only son, from Me.”
Then Abraham lifted his eyes and looked, and there behind him was a ram caught in a thicket by its horns. So Abraham went and took the ram, and offered it up for a burnt offering instead of his son. And Abraham called the name of the place, The-Lord -Will-Provide; as it is said to this day, “In the Mount of the Lord it shall be provided.”
Then the Angel of the Lord called to Abraham a second time out of heaven, and said: “By Myself I have sworn, says the Lord, because you have done this thing, and have not withheld your son, your only son — blessing I will bless you, and multiplying I will multiply your descendants as the stars of the heaven and as the sand which is on the seashore; and your descendants shall possess the gate of their enemies. In your seed all the nations of the earth shall be blessed, because you have obeyed My voice.”
Abraham called the place, “The Lord Will Provide.” Many speculate that the place on Mt. Moriah where this sacrifice took place, may be the same as the Temple Mount. Jesus was crucified on a hill just outside Jerusalem. God provided the sacrifice to atone for our sins, for our redemption. it is only fitting that Jesus reveals Himself here as The Angel of the Lord to offer a substitute for Abraham’s sacrifice and to promise blessing to all the world through Abraham’s descendants, and through Himself.
Christ has redeemed us from the curse of the law, having become a curse for us (for it is written, “Cursed is everyone who hangs on a tree”), that the blessing of Abraham might come upon the Gentiles in Christ Jesus, that we might receive the promise of the Spirit through faith.
Brethren, I speak in the manner of men: Though it is only a man’s covenant, yet if it is confirmed, no one annuls or adds to it. Now to Abraham and his Seed were the promises made. He does not say, “And to seeds,” as of many, but as of one, “And to your Seed,” who is Christ. And this I say, that the law, which was four hundred and thirty years later, cannot annul the covenant that was confirmed before by God in Christ, that it should make the promise of no effect. For if the inheritance is of the law, it is no longer of promise; but God gave it to Abraham by promise.
Just like God provided a lamb to Abraham for the sacrifice, just as Abraham was faithful enough to sacrifice his one and only son, so God was faithful to offer His one and only Son to die on the cross in our place so that our sins may be forgiven if we have faith in Him.
The next day John saw Jesus coming toward him, and said, “Behold! The Lamb of God who takes away the sin of the world!
