"And what more shall I say? I do not have time to tell about Gideon, Barak, Samson and Jephthah, about David and Samuel and the prophets, who through faith conquered kingdoms, administered justice, and gained what was promised; who shut mouths of lions, quenched the fury of the flames, and escaped the edge of the sword; whose weakness was turned to strength; and who became powerful in battle and routed foreign armies." NIV translation
Paul explains that he is just giving us a brief look into this hall of faith. Books and, in fact, a whole library could be written about the long list of people who have walked in faith. The main thing that they all had in common was the fact that it was only through the power of God that they were made strong. They are winners because of the power of God! We must also remember that, throughout the Bible, it was mostly misfits and the weak that God has used for His purposes.
