In the sermon titled "A More Excellent Ministry," Mike McInnis addresses the profound theological concept of Christ as the great High Priest and mediator of a better covenant. He emphasizes that the priesthood of Christ, superior to the Levitical priesthood, is not based on human performances or the Mosaic law but on God’s grace and the effectiveness of Christ’s singular sacrifice for sin. Scripture references from Hebrews 7:26-8:13 illustrate how Christ embodies the new covenant that God promised—one founded on better promises wherein God writes His laws on believers' hearts rather than imposing them externally through the law of Moses. The practical significance of this sermon lies in its clear exposition of the Reformed doctrine of salvation by grace alone, reinforcing that salvation is rooted entirely in Christ's finished work and not in human effort or obedience.

The Bible presents Christ as our great high priest who offered Himself as the perfect sacrifice for our sins, fulfilling the law and establishing a new covenant with His people.
The Book of Hebrews describes Christ as our great high priest who was uniquely suited for us—holy, harmless, undefiled, and exalted above the heavens. Unlike the earthly priests who had to offer sacrifices for their own sins before the people's, Christ offered Himself once for all, achieving complete salvation for those He represents (Hebrews 7:26-27). His priesthood is not after the order of Aaron but of Melchizedek, highlighting the eternal and unchanging nature of His mediatorial role, established upon better promises as outlined in the new covenant. Through His sacrificial death, Christ has procured eternal redemption for His people, perfecting forever those who are being sanctified (Hebrews 10:14).
Hebrews 8:1-2, Hebrews 7:26-27, Hebrews 10:14
The new covenant is better because it is based on the completed work of Christ, who offers unconditional grace and a relationship with God, unlike the conditional requirements of the law.
The Book of Hebrews explains that the new covenant is established upon better promises than the old covenant, which was based on adherence to the Law of Moses. The first covenant had shortcomings; it demanded perfect obedience from the people, ultimately leading to failure and condemnation (Hebrews 8:7). The new covenant, however, is initiated through Jesus Christ, who perfectly fulfilled the law and offers mercy and grace instead of judgment. This is evidenced by God's promise to put His laws in our minds and hearts, ensuring a direct relationship where He declares, 'I will be merciful to their unrighteousness, and their sins and iniquities will I remember no more' (Hebrews 8:12). This unconditional aspect of the new covenant instills hope and security in the believer, as it centers on Christ's redemptive work rather than human effort.
Hebrews 8:7-12, Hebrews 10:14
Christ's priesthood is essential because He is the only mediator between God and man, having provided the perfect sacrifice for sin that fully satisfies divine justice.
The priesthood of Christ is foundational to sovereign grace theology as it establishes Him as the sole mediator for humanity. According to Hebrews, every earthly priest was limited in that they had to repetitively offer sacrifices that could never fully atone for sin. In contrast, Christ, as the high priest, offered Himself once for all, securing eternal redemption for His people (Hebrews 7:27). His priesthood is after the order of Melchizedek, symbolizing an eternal and effective ministry (Hebrews 7:16). Through Him, believers receive complete forgiveness, and as Hebrews 10:12 proclaims, 'But this man, after he had offered one sacrifice for sins forever, sat down on the right hand of God.' This act not only fulfills the law but also grants believers direct access to God, unencumbered by the weight of sin, affirming their secure and unbroken relationship with the Father.
