Some helpful Scripture:
Romans 4:17-21
Abraham’s name when he was born was Abram which meant “exalted father.” Yet when he was married, he found that his wife couldn’t have children. She was barren. Humanly speaking, he not only could not be an exalted father, but he also couldn’t be a father at all. God wanted to make a nation out of Abram, a nation into which He could send Jesus, our Savior and King! He told Abram that Sarah was going to have a baby! The Bible says of Abram, “And being not weak in faith, he considered not his own body now dead, when he was about an hundred years old, neither yet the deadness of Sarah’s womb: He staggered not at the promise of God through unbelief ; but was strong in faith, giving glory to God; And being fully persuaded that, what he had promised, he was able also to perform.” (Romans 4: 19-21). God later changed Abram’s name to Abraham, meaning, “father of a multitude,” and raised up a nation of his descendants into which Jesus was born.

When we sense that God is leading us to do something or receive something that seems humanly impossible, or we are challenged to pray for something that we know is right and in God’s will yet seems humanly impossible, I believe we should follow Abraham’s example. I believe that we should be “fully persuaded” and “strong in faith” and that we should “stagger not at the promises of God” through unbelief but that we should believe that what He has promised He will perform!
