Jesus Christ is our mediator because He offered Himself as the ultimate atonement for our sins, fulfilling the role of the high priest perfectly.
The New Testament confirms Jesus as our mediator between God and humanity, as stated in Hebrews 4:14-16, where He is described as a great high priest who ascended into heaven. Unlike the high priests of the Old Testament who had to offer sacrifices repeatedly, Christ offered Himself once for all as the perfect sacrifice (Hebrews 7:27). His shedding of blood was the atonement necessary to satisfy God's justice, allowing believers to come boldly to the throne of grace. This mediation is essential, as no one can come to God without a high priest, emphasized throughout both the Old and New Testaments.
