I can fill a church speaking on Revelation and empty it speaking on Romans.
He is preeminent in creation because He is the Creator. He is preeminent in redemption for He is the Redeemer. He is preeminent in the church because He is the One who gave Himself for the church.
A poor believer [monetarily] certainly is looked down upon in certain churches, and yet he may be the richest man spiritually in that church.
