Several years ago there was a flood of WWJD merchandise on the market. The WWJD stands for "What Would Jesus Do?" It's based on the classic Christian book,
In His Steps, by Charles M Sheldon. The book recounts a whole town brought into revival because people began asking themselves this question in the process of daily life. It's been a while since I've read it, but the author, the pastor of a church, challenged himself and his congregation to live out the Gospel in their daily lives by answering this question. The book started out as a message preached in 1896. It's well worth the read if you haven't already done so.
