He is relevant as the King of Israel. In fact, Israel will not be able to enjoy its status as the premier nation on earth without the King of the Jews taking his rightful place on the throne at the place of the name of YHWH Tsabaoth.
Sorry...the gentilish "church" is not the center of God's plan. It is clear from the scriptures, Old Testament and New, that Jesus was sent for the lost sheep of Israel. We gentiles received blessing because the Jews rejected Messiah. If their rejection meant blessing for us, imagine what their acceptance will be.
I am sorry to discover that the tail continues to wag the dog in your universe -- or should I say, in your deranged imagination, the God. Jesus matters less than an ethnic group whose existence is defined by their denial of Him. So, of course, this ethic group matters more to God than His Beloved Son. The creation must be revered, honored, abased before, and worshipped, in deference to the Creator.
Folks, this is where Scofield's dispensationalism will take you if you push it far enough -- clear out of the center of God's Will, which is -- the Seed to whom, and through whom, all of the earth, all the tribes of the earth, or should I say, all the FAITHFUL tribes of the earth, inherit the blessings promised Abraham.
It's a dangerous thing to deny / denigrate / belittle Jesus before men. Dishonoring the Son is not something you do if you want God's blessings on your life.
