The phrase "What would Jesus do?", often abbreviated to WWJD, became popular particularly in the United States in the late 1800s after the widely read book by Charles Sheldon entitled, “In His Steps: What Would Jesus Do.” The phrase had a resurgence in the US and elsewhere in the 1990s and as a personal motto for adherents of 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.
