Jesus declared this in John 6:62,
"What then if you see the Son of Man ascending to where He was before?"
Jesus declared this in John 17:5,
"Now, Father, glorify Me together with Yourself, with the glory which I had with You before the world was."
No prophet who came before or after Jesus ever declared such words. Either Jesus was declaring the truth, or he is not worthy to be called a prophet.
If Jesus is telling the truth, He is worthy to be worshipped as Lord (Acts 2:33).
