To the world, they were fanatics, heretics, narrow-minded fools...outsiders, worthy only of rejection and ridicule. But they didn't live to please the world; they lived to please Christ. With courage, conviction, and great commitment to the Lord, they were willing to stand up and stand out for Christ. Too often, however, their stories have been unknown or forgotten.

In these pages, meet fifteen leaders from history who followed Christ and changed the world. Their testimonies will stir your faith, strengthen your commitment, and renew your dedication to Christ.
