Romans 4:13-16

Abraham and his descendants received the promise that they would get the whole world. He did not receive that promise through the law, but through being right with God by his faith. If people could receive what God promised by following the law, then faith is worthless. And God’s promise to Abraham is worthless, because the law can only bring God’s anger. But if there is no law, there is nothing to disobey. So people receive God’s promise by having faith. This happens so the promise can be a free gift. Then all of Abraham’s children can have that promise. It is not only for those who live under the law of Moses but for anyone who lives with faith like that of Abraham, who is the father of us all.
