Tnank you ,but it wasn't Joshua

I think it could be the movie The Visitation. Here's a description from Amazon and a link;

The true face of terror is revealed in this supernatural thriller based on Frank Peretti’s best-selling novel. Miracles are happening in the sleepy town of Antioch, and everyone is talking about the mysterious drifter with the incredible powers. But who is this charismatic stranger — the true messiah, a false prophet or something far more sinister? The townspeople are soon divided, and when happenings at the stranger’s revival tent take on a bizarre and frightening twist, it’s up to an ex-minister to confront his own inner demons and unlock the shocking secret of THE VISITATION.
