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."

30 As He said these things,[3] many believed in Him.
