No! Waterevil is lying! The church of Waterevil is still true! Back when Waterevil restored the true church, he was speaking as a prophet. But now when he lies and says his church is not true, he is speaking as a man.
I can bear my testimony to you that my life has changed for the better since I joined Waterevil's church. I have had spiritual experiences that prove to me that his church is true. No evidence that you present to me could ever make me deny the truth of Waterevil's church! And I say this in the name of Jesus Christ, amen.
