14 If people could receive what God promised by following the law, then faith is worthless. And God’s promise to Abraham is worthless,
15 because the law can only bring God’s anger. But if there is no law, then there is nothing to disobey.
16 So people receive God’s promise by having faith. This happens so that the promise can be a free gift. And if the promise is a free gift, then all of Abraham’s children can have that promise. The promise is not only for those people that live under the law of Moses. It is for anyone who lives with faith like Abraham. He is the father of us all.
17 As it is written in the Scriptures: “I am making you a father of many nations.” This is true before God. Abraham believed in God—the God who gives life to the dead and decides that things will happen that have not yet happened.
18 There was no hope that Abraham would have children. But Abraham believed God and continued hoping. And that is why he became the father of many nations. As God told him, “Your descendants will also be too many to count.”
19 Abraham was almost 100 years old, much past the age for having children. Also, Sarah could not have children. Abraham thought about all this. But his faith in God did not become weak.
20 He never doubted that God would keep his promise. Abraham never stopped believing. He grew stronger in his faith and gave praise to God.
