Hebrews 11:1, 7, 11

Faith shows the reality of what we hope for; it is the evidence of things we cannot see.

It was by faith that Noah built a large boat to save his family from the flood. He obeyed God, who warned him about things that had never happened before. By his faith Noah condemned the rest of the world, and he received the righteousness that comes by faith.

It was by faith that even Sarah was able to have a child, though she was barren and was too old. She believed that God would keep his promise.
