Theology. It’s good for you. Gary is church historian by trade. His writing, speaking, and teaching explores the Christian past to equip today's disciples. Gary suggests that we all claim the riches we didn't know was ours. He says the more you know about your own family history, the wiser you can be about growing up and thriving. Same goes for your knowledge of your Christian heritage. Follow the good examples. Avoid repeating past mistakes. Find some wisdom in a world of confusion.
