WWJD stands for "What Would Jesus Do?" It is a question that many Christians ask themselves when faced with moral or ethical decisions. The idea behind this phrase is to encourage individuals to think about how Jesus would react or respond to a situation and then use that as a guide for their own actions.

The origin of the WWJD movement can be traced back to the novel "In His Steps" by Charles Sheldon, which was first published in 1896. The book tells the story of a group of Christians who commit to living their lives according to the question "What would Jesus do?" This commitment leads them to make radical changes in their lives and to become more involved in helping those in need.

In the 1990s, the WWJD movement experienced a resurgence in popularity, particularly among young people. The phrase became a popular slogan on T-shirts, bracelets, and other merchandise. The WWJD bracelet, in particular, became a widely recognized symbol of the movement.
