Radical Christianity Is Normal by Francis Chan

"When I entered the seminary, the President warned us. "Be careful. You will study this book. Make sure when you hear something and read something, then you'd better do it. When you are convicted about, you'd better do something about it. Because if you don't, the next time it will be easier you study the word of God, be convicted and do nothing about it. Pretty soon it becomes a habit. You study the word of God and do nothing about it. It's very very dangerous habit."
