Genesis 15:1-2

The Cutting of the Covenant

15:1 After these things the word of the Lord came to Abram in a vision: “Fear not, Abram! I am your shield and the one who will reward you in great abundance.”

15:2 But Abram said, “O sovereign Lord, what will you give me since I continue to be childless, and my heir is Eliezer of Damascus?”

Genesis 18:11-13

18:11 Abraham and Sarah were old and advancing in years; Sarah had long since passed menopause.) 18:12 So Sarah laughed to herself, thinking, “After I am worn out will I have pleasure, especially when my husband is old too?”

18:13 The Lord said to Abraham, “Why did Sarah laugh and say, ‘Will I really have a child when I am old?’

Joshua 24:3

24:3 but I took your father Abraham from beyond the Euphrates and brought him into the entire land of Canaan. I made his descendants numerous; I gave him Isaac,

Romans 4:1-5

The Illustration of Justification

4:1 What then shall we say that Abraham, our ancestor according to the flesh, has discovered regarding this matter? 4:2 For if Abraham was declared righteous by the works of the law, he has something to boast about – but not before God. 4:3 For what does the scripture say? “Abraham believed God, and it was credited to him as righteousness.” 4:4 Now to the one who works, his pay is not credited due to grace but due to obligation. 4:5 But to the one who does not work, but believes in the one who declares the ungodly righteous, his faith is credited as righteousness.

Romans 4:16-24

4:16 For this reason it is by faith so that it may be by grace, with the result that the promise may be certain to all the descendants – not only to those who are under the law, but also to those who have the faith of Abraham, who is the father of us all 4:17 (as it is written, “I have made you the father of many nations”). He is our father in the presence of God whom he believed – the God who makes the dead alive and summons the things that do not yet exist as though they already do. 4:18 Against hope Abraham believed in hope with the result that he became the father of many nations according to the pronouncement, “so will your descendants be.” 4:19 Without being weak in faith, he considered his own body as dead (because he was about one hundred years old) and the deadness of Sarah’s womb. 4:20 He did not waver in unbelief about the promise of God but was strengthened in faith, giving glory to God. 4:21 He was fully convinced that what God promised he was also able to do. 4:22 So indeed it was credited to Abraham as righteousness.

4:23 But the statement it was credited to him was not written only for Abraham’s sake, 4:24 but also for our sake, to whom it will be credited, those who believe in the one who raised Jesus our Lord from the dead.
