Romans 4:13, 16-18, 22
Chapter 4
13
The Promise of Descendants
If God promised Abraham, or rather his descendants, that the world would belong to him, this was not because of his obeying the law, but because he was just and a friend of God, through faith.16
For that reason, faith is the way, and everything is given by grace; the promises of Abraham are fulfilled for all his descendants, not just his children according to the law, but also for everyone who has believed. Abraham is the father of all of us,
17
as it is written: I will make you the father of many nations. He is our father in the eyes of Him who gives life to the dead, and calls into existence what does not yet exist, for this is the God in whom he believed.
18
Abraham believed and hoped despite all odds, thus becoming the father of many nations, as he was told: See how numerous your descendants will be.
22
Therefore, his faith was credited to him as righteousness.
