Romans 4:13-22

God promised Abraham and his descendants that they would have an heir who would reign over the world. This royal promise was not fulfilled because Abraham kept all the law, but through the righteousness that was transferred by faith. For if keeping the law earns the inheritance, then faith is robbed of its power and the promise becomes useless. For the law provokes punishment, and where no law exists there cannot be a violation of the law. The promise depends on faith so that it can be experienced as a grace-gift, and now it extends to all the descendants of Abraham. This promise is not only meant for those who obey the law, but also to those who enter into the faith of Abraham, the father of us all. That’s what the Scripture means when it says: “I have made you the father of many nations.” He is our example and father, for in God’s presence he believed that God can raise the dead and call into being things that don’t even exist yet. Against all odds, when it looked hopeless, Abraham believed the promise and expected God to fulfill it. He took God at his word, and as a result he became the father of many nations. God’s declaration over him came to pass: “Your descendants will be so many that they will be impossible to count!” In spite of being nearly one hundred years old when the promise of having a son was made, his faith was so strong that it could not be undermined by the fact that he and Sarah were incapable of conceiving a child. He never stopped believing God’s promise, for he was made strong in his faith to father a child. And because he was mighty in faith and convinced that God had all the power needed to fulfill his promises, Abraham glorified God! So now you can see why Abraham’s faith was credited to his account as righteousness before God.
