Genesis 22:7-13 And Isaac spoke to Abraham his father, and said, My father: and he said, Here am I, my son. Then he said, Behold the fire and the wood: but where is the lamb for a burnt offering? And Abraham said, My son, God will provide Himself a lamb for a burnt offering: so they went both of them together. And they came to the place which God had told him of; 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. 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 you fear God, since you have not withheld your son, your only son, from Me. Then Abraham lifted up 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.
One of the major themes of Yom Teruah (Feast of Trumpets) is called Akedat Yitzchak, which means the Binding of Isaac. According to Jewish tradition, God told Abraham that the ram's horn – otherwise known as a shofar – should be blown on Feast of Trumpets to remind people of the sacrifice that God provided Himself when Abraham was about to offer Isaac on Mount Moriah. It's abundantly clear that this event in the life of Abraham and Isaac foreshadowed God the Father's offering of His Son, providing Yeshua (Jesus) as a sacrifice for all men.
As we now are in the midst of the "Days of Awe" – traditionally, a time of repentance between Yom Teruah and Yom Kippur – let us take the time to examine ourselves, turning from sin again, toward our loving Creator, as we celebrate the fact that our names are written in the Lamb’s book of life. Through His perfect sacrifice, the Lamb of God, Yeshua, God's forgiveness is eternal and His love, everlasting.
