1 After this, the word of the Lord came to Abram in a vision: “Do not be afraid, Abram.  I am your shield, your very great reward.” 2 But Abram said, “Sovereign Lord, what can you give me since I remain childless and the one who will inherit my estate is Eliezer of Damascus?” 3 And Abram said, “You have given me no children; so a servant in my household will be my heir.” 4 Then the word of the Lord came to him: “This man will not be your heir, but a son who is your own flesh and blood will be your heir.” 5 He took him outside and said, “Look up at the sky and count the stars—if indeed you can count them.” Then he said to him, “So shall your offspring be.” 6 Abram believed the Lord, and he credited it to him as righteousness.
Genesis 15:1-6

God the promiser

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

1 What then shall we say that Abraham, our forefather according to the flesh, discovered in this matter? 2 If, in fact, Abraham was justified by works, he had something to boast about—but not before God. 3 What does Scripture say? “Abraham believed God, and it was credited to him as righteousness.” 4 Now to the one who works, wages are not credited as a gift but as an obligation. 5 However, to the one who does not work but trusts God who justifies the ungodly, their faith is credited as righteousness.
Romans 4:1-5

God the performer

7 He also said to him, “I am the Lord, who brought you out of Ur of the Chaldeans to give you this land to take possession of it.” 8 But Abram said, “Sovereign Lord, how can I know that I will gain possession of it?” 9 So the Lord said to him, “Bring me a heifer, a goat and a ram, each three years old, along with a dove and a young pigeon.” 10 Abram brought all these to him, cut them in two and arranged the halves opposite each other; the birds, however, he did not cut in half. 11 Then birds of prey came down on the carcasses, but Abram drove them away.
Genesis 15:7-11

God the perseverer

12 As the sun was setting, Abram fell into a deep sleep, and a thick and dreadful darkness came over him. 13 Then the Lord said to him, “Know for certain that for four hundred years your descendants will be strangers in a country not their own and that they will be enslaved and mistreated there. 14 But I will punish the nation they serve as slaves, and afterward they will come out with great possessions.
Genesis 15:12-14

17 When the sun had set and darkness had fallen, a smoking firepot with a blazing torch appeared and passed between the pieces. 18 On that day the Lord made a covenant with Abram and said…
