Bob and Joan Tyson were living ordinary lives until God called them to do extraordinary things—the kind we read about in the Bible. It wasn't from a rock, but God clearly provided water. No pigs ran over a cliff, but a demoniac was saved and freed from Satan and the cage where he had been locked for eight years. No loaves and fishes were multiplied, but thousands are fed daily through their work. Let the exploits of this missionary family challenge you to do great exploits in God's name.
