[From the online Jesse Tree.]
A reading from the book of Genesis (22:15-18):
The angel of the LORD called to Abraham a second time from heaven, and said, “By myself I have sworn, says the LORD, because you have done this, and have not withheld your son, your only son, I will indeed bless you, and I will multiply your descendants as the stars of heaven and as the sand which is on the seashore. And your descendants shall possess the gate of their enemies, and by your descendants shall all the nations of the earth bless themselves, because you have obeyed my voice.”
Abraham lived long, long ago in the city of Ur, where people worshipped the moon and other things as gods. In those days, his name was Abram. But the one true God called Abram to leave his home and travel far, far away to a new land that God would show him, and because Abraham believed God and obeyed him his name was changed to Abraham, which means “father of many nations.”
It seemed like a funny name at the time, because Abraham didn’t have any children. He and his wife were old, and it didn’t seem like they would ever have children. But by a miracle, God gave them a boy named Isaac. Everything seemed fine: Abraham believed God’s promise about the land and about his children, and God had brought him to the land and had given him a child.
But God wanted to push Abraham to be even greater than he was already. He put Abraham through a terrible test by telling him to kill his son Isaac as a sacrifice. How could God give Abraham many descendants if Abraham’s only son were dead? And how could God ask Abraham to kill his own child? But Abraham trusted God even when he didn’t understand. He went to the appointed place, got everything ready, and raised his hand to do what God had said—but suddenly God’s angel called out him and stopped him. He gave him a ram to sacrifice instead of Isaac, which is why today’s ornament is a sheep.
Because Abraham had obeyed him, God promised him not only the land and many descendants, but also that all the nations of the world would be blessed through Abraham’s descendant. With this promise, light dawned over the darkness left by Adam and Eve. God had begun something with Abraham that would become the Advent story we tell every year now.
