How can you say Jesus is not man?

Regardless what we might think about if he is also God, the Bible is very clear that he is a man. See for example 1 Tim. 2:5 "the man Christ Jesus". Very clear. That was written years after Jesus was resurrected. So he was man when Paul wrote this, and he is man now.

And you claim Isaiah wrote to worship God only, but that is not what Isaiah wrote, read the verse carefully. And read also for example Rev. 3:9, the false Jews will be forced to worship the angel of Philadelphia. That angel cannot be God. No verse says to worship God only. We are to worship whomever God tells us to worship.
