Why is it necessary for Christ to have the preeminence in preaching?

In the life of a believer and in preaching, Christ must be preeminent because He is the only mediator between God and humanity. As 1 Timothy 2:5 states, there is one mediator, the man Christ Jesus, and without Him, there can be no reconciliation. The preaching of the gospel must center on Christ and His work—His incarnation, atonement, resurrection, and ascension—because He alone accomplishes the saving work necessary for sinful humans to be restored to a right relationship with God. When Christ is placed at the forefront of preaching, the message becomes clear and powerful, drawing sinners to recognize their need and to come to Him in faith.
