John 8:27-29

Amplified Bible

²⁷ They did not realize [or have the spiritual insight to understand] that He was speaking to them about the Father. ²⁸ So Jesus said, “When you lift up the Son of Man [on the cross], you will know then [without any doubt] that I am He, and that I do nothing on My own authority, but I say these things just as My Father taught Me. ²⁹ And He who sent Me is [always] with Me; He has not left Me alone, because I always do what pleases Him.”
