The Second Lesson:
God promises to faithful Abraham that in his seed shall all the nations of the earth be blessed.
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 make your offspring as numerous as the stars of heaven and as the sand that is on the seashore. And your offspring shall possess the gate of their enemies, and by your offspring shall all the nations of the earth gain blessing for themselves, because you have obeyed my voice.” (Genesis 22:15-18)
“O Come, O Come, Emmanuel”
