What does the Bible say about faith like Abraham's?

Abraham's faith serves as a profound illustration of how true belief operates. Romans 4 highlights that Abraham believed God, who quickens the dead and calls those things which do not exist as though they were. Faith is fundamentally centered on a person—God Himself—rather than on human understanding or circumstances. As noted in Romans 4:19-21, Abraham did not waver in disbelief despite his age and the deadness of Sarah's womb; instead, he was fully convinced that God could fulfill His promise. This faith is a gift from God, evidencing the assurance of His unchanging nature and His ability to perform what He has promised.
