I see it now!
John 13:36 KJV
Simon Peter said unto him, Lord, whither goest thou? Jesus answered him, Whither I go, thou canst not follow me now; but thou shalt follow me afterwards.

It's not the only time he spoke in those same terms. In John 8, he told the Jewish leaders-- Where I'm going, you cannot come... And- You are from below, I am from above. You are from this world. I am not from this world.
But-- Jesus was from around here. He was born in Bethlehem. He grew up in Nazareth. He wasn't from above. So he wasn't speaking of himself. He wasn't speaking of his physical person, but of and by the spirit within him.
