Abraham | Covenants and The Christ

“…Long ago, your fathers lived beyond the Euphrates, Terah, the father of Abraham and of Nahor; and they served other gods.” (Joshua 24:2)

Now the Lord said to Abram, “Go from your country and your kindred and your father’s house to the land that I will show you.  2  And I will make of you a great nation, and I will bless you and make your name great, so that you will be a blessing.  3  I will bless those who bless you, and him who dishonors you I will curse, and in you all the families of the earth shall be blessed.” (Genesis 12:1-3)

And God said to Abraham, “As for Sarai your wife, you shall not call her name Sarai, but Sarah shall be her name.  16  I will bless her, and moreover, I will give  you a son by her. I
will bless her, and she shall become nations; kings of peoples shall come from her.” (Genesis 17:15-16)

The Lord visited Sarah as he had said, and the Lord did to Sarah as he had promised.  2  And Sarah conceived and bore Abraham a son in his old age at the time of
which God had spoken to him.  3  Abraham called the name of his son who was born to him, whom Sarah bore him, Isaac.   4  And Abraham circumcised his son Isaac when he
was eight days old, as God had commanded him.  5  Abraham was a hundred years old when his son Isaac was born to him.  6  And Sarah said, “God has made laughter for me; everyone who hears will laugh over me.”  7  And she said, “Who would have said to Abraham that Sarah would nurse children? Yet I have borne him a son in his old age.” (Genesis 21:1-7)

After these things God tested Abraham and said to him, “Abraham!” And he said, “Here I am.”  2  He said, “Take 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.”  3  So Abraham rose early in the morning, saddled his donkey, and took two of his young men with him, and his son Isaac. And he cut the wood (Genesis 22:1-3)

And Abraham took the wood of the burnt offering and laid it on Isaac his son. And he took in his hand the fire and the knife. So they went both of them together.  7  And Isaac
said to his father Abraham, “My father!” And he said, “Here I am, my son.” He said,“Behold, the fire and the wood, but where is the lamb for a burnt offering?”  8  Abraham said, “God will provide for himself the lamb for a burnt offering, my son.” So they went both of them together. 9  When they came to the place of which God had told him, Abraham built the altar there and laid the wood in order and bound Isaac his son and laid him on the altar, on top of the wood.  10  Then Abraham reached out his hand and took the knife to slaughter his son.  11  But the angel of the Lord called to him from heaven and said, “Abraham, Abraham!” And he said, “Here I am.”  12  He said, “Do not lay your hand on the boy or do anything to him, for now I know that you fear God, seeing you have not withheld your son, your only son, from me.”  13  And Abraham lifted up his eyes and looked, and behold, behind him was a ram, caught in a thicket by his horns. And Abraham went and took the ram and offered it up as a burnt offering instead of his son. (Genesis 22:6-13)

For the promise to Abraham and his offspring that he would be heir of the world did not come through the law but through the righteousness of faith. (Romans 4:13)

Abram believed the Lord, and he credited it to him as righteousness. (Genesis 15:6)

For by grace you have been saved through faith. And this is not your own doing; it is the gift of God (Ephesians 4:8)
