Bible Verses About Unbelief: Miracles designed to convince those in

If I am not doing the works of My Father, then do not believe Me.

But if I am doing them, even though you do not believe Me, believe the works themselves, so that you may know and understand that the Father is in Me, and I am in the Father.”

Tongues, then, are a sign, not for believers, but for unbelievers. Prophecy, however, is for believers, not for unbelievers.
