WWJD是一个4字母的缩写，代表的是英语“What Would Jesus Do”的缩写，也就是说“如果让耶稣基督来做，祂会怎么做？”的意思。

WWJD是一项2000年代开始的新兴属灵运动，是北美基督徒团体为重新唤醒青少年信徒的灵性修养而发起的活动。活动主要透过电话绳、文身、襟章等各种潮流服饰和玩意，来提高青少年对自己信仰的认同感。

The phrase "What would Jesus do?" (often abbreviated to WWJD) became popular in the United States in the 1990s and as a personal motto for adherents of Evangelical Christianity who used the phrase as a reminder of their belief in a moral imperative to act in a manner that would demonstrate the love of Jesus through the actions of the adherents.
