Some of my heroes in the faith are the biggest givers I know.
Dr. Rick Warren is a well known, pastor, philanthropist, writer and big-time giver. He is the author of a New York Times bestseller, The Purpose Driven Life. Besides his influence to me as a pastor and evangelist, Dr. Warren has really challenged me in my giving. He and his wife give away 90% of their income.
You read that right, 90%!
He posted an article on his blog I think you will find encouraging and helpful.
