John 8:28-30 Amplified Bible, Classic Edition (AMPC)
28 So Jesus added, When you have lifted up the Son of Man [on the cross], you will realize (know, understand) that I am He [for Whom you look] and that I do nothing of Myself (of My own accord or on My own authority), but I say [exactly] what My Father has taught Me.
29 And He Who sent Me is ever with Me; My Father has not left Me alone, for I always do what pleases Him.
30 As He said these things, many believed in Him [trusted, relied on, and adhered to Him].
John 8:28-30 New International Version (NIV)
28 So Jesus said, “When you have lifted up[a] the Son of Man, then you will know that I am he and that I do nothing on my own but speak just what the Father has taught me. 29 The one who sent me is with me; he has not left me alone, for I always do what pleases him.” 30 Even as he spoke, many believed in him.
