Romans 4:18

18 Even when there was no reason for hope, Abraham kept hoping—believing that he would become the father of many nations. For God had said to him, “That’s how many descendants you will have!”

Romans 4:18 Meaning and Commentary

Romans 4:18

Who against hope believed in hope
Abraham believed the promise of God,

that he might become the father of many nations,
being assisted by a supernatural aid: "in hope"; of the fulfilment of it by the grace and power of God: "against hope": against all visible, rational grounds of hope; Sarah's womb and his own body being dead, but inasmuch as God had said it, he believed:

according to that which is spoken, so shall thy seed be;
his faith rested upon the word of God, which showed the nature of it, and that it was of the right kind.

Romans 4:18 In-Context

16 So the promise is received by faith. It is given as a free gift. And we are all certain to receive it, whether or not we live according to the law of Moses, if we have faith like Abraham’s. For Abraham is the father of all who believe.
17 That is what the Scriptures mean when God told him, “I have made you the father of many nations.” This happened because Abraham believed in the God who brings the dead back to life and who creates new things out of nothing.
18 Even when there was no reason for hope, Abraham kept hoping—believing that he would become the father of many nations. For God had said to him, “That’s how many descendants you will have!”
19 And Abraham’s faith did not weaken, even though, at about 100 years of age, he figured his body was as good as dead—and so was Sarah’s womb.
20 Abraham never wavered in believing God’s promise. In fact, his faith grew stronger, and in this he brought glory to God.
