Dr. James White said in his teaching on Hebrews: "The only true path to exaltation and being commended by God is that of humiliation. The person who seeks exaltation will be humbled. The person who is humbled will be exalted by God."
Instead of exalting Christ in our life and humbling ourselves, we so often exalt ourselves and bring Christ down from where He rightfully belongs and that is Lord and God of all. Instead of exalting Christ, we exalt idols after our own imaginations and fleshly desires and we worship them which means that we are ultimately worshiping ourselves instead of God.
John MacArthur in his commentary on the book of Hebrews states the following: "Keep in mind that the book of Hebrews is written to Jewish people, primarily to Jewish believers but also to Jewish unbelievers. Both groups are pressed with the truth that the New Covenant is better than the Old – that Jesus Christ is the better Priest, and the better Mediator, and that He is the final Priest and the final Sacrifice at the same time (MacArthur, 1983. p.22)
