John 10:37-38

If I do not do the works of My Father [that is, the miracles that only God could perform], then do not believe Me. But if I am doing them, even if you do not believe Me or have faith in Me, [at least] believe the works [that I do—admit that they are the works of God], so that you may know and keep on knowing [clearly—without any doubt] that the Father is in Me, and I am in the Father [that is, I am One with Him].”
