“Then said Jesus unto them, When ye have lifted up the Son of man, then shall ye know that I am he, and that I do nothing of myself; but as my Father hath taught me, I speak these things.”
King James Version (KJV)
8:28 When ye shall have lifted up - On the cross, ye shall know - And so many of them did, that I AM - God over all; and that I do nothing of myself - Being one with the Father.
Joh 8:28 When ye have lifted up the Son of man. Lifted him up on the cross. His "lifting up" would be the means of breaking down unbelief. We can see how this was verified. In fifty days after he was lifted up three thousand believed in a single day (Ac 2:41), and the work of faith went on until the civilized world acknowledged him as King.
