Jesus said, "I am the First" (Revelation 1:17). With Isaiah 44:6, God says "I am the first and I am the last, and apart from me there is no God."
There can only be one who is THE FIRST.
You have three choices:
1. Call Jesus a liar or lunatic
2. Accept him as the one true God
3. Become a lunatic yourself by believing that more than one can be THE FIRST.

The man, whom God became, was subject to the Father but it was God the Father who became man. To understand this, one first must become knowledgeable about the nature of God and his omnipotence. If you conceive of God as a sort of "big guy upstairs", then you won't comprehend this but it will seem as foolishness to you. Biblically God is described as unique, he is eternal as to the past and is an omnipotent and everywhere present Spirit. He is not spatially constrained as false deities are conceived of. Do you wish to understand who He is, or do you wish to continue to limit yourself to a sort of deity that is like a false one?
