The Promise And The Command

The promise:
But God said, "No, but Sarah your wife will bear you a son, and you shall call his name Isaac; and I will establish My covenant with him for an everlasting covenant for his descendants after him. (Genesis 17:19 NASB)

The command:
He said, "Take now your son, your only son, whom you love, Isaac, and go to the land of Moriah, and offer him there as a burnt offering on one of the mountains of which I will tell you." (Genesis 22:2 NASB)

The faith:
He considered that God was able even to raise him from the dead, from which, figuratively speaking, he did receive him back. (Hebrews 11:19 ESV)

The evidence of faith:
Abraham said to his young men, "Stay here with the donkey, and I and the lad will go over there; and we will worship and return to you." (Genesis 22:5 NASB)

The fulfilment of faith:
And Abraham stretched forth his hand, and took the knife to slay his son. And the angel of the Lord called unto him out of heaven, and said, Abraham, Abraham: and he said, Here am I. And he said, Lay not thine hand upon the lad, neither do thou any thing unto him: for now I know that thou fearest God, seeing thou hast not withheld thy son, thine only son from me. And Abraham lifted up his eyes, and looked, and behold behind him a ram caught in a thicket by his horns: and Abraham went and took the ram, and offered him up for a burnt offering in the stead of his son. And Abraham called the name of that place Jehovahjireh: as it is said to this day, In the mount of the Lord it shall be seen. (Genesis 22:10-14 KJV)

When the command of God threatened to nullify the promise of God, Abraham responded with the faith that God is able to raise Isaac from the dead and the promise of God cannot be broken. While the response of God is not a spectacular miracle, He provided a substitute to fulfil His commandment.

The next day he saw Jesus coming toward him, and said, "Behold, the Lamb of God, who takes away the sin of the world! This is he of whom I said, 'After me comes a man who ranks before me, because he was before me.' I myself did not know him, but for this purpose I came baptizing with water, that he might be revealed to Israel." (John 1:29-31 ESV)

While the wages of sin is death but God did provide a substitute to fulfil His law. We only have to rest on His promise.
