Why is the concept of Jesus as our mediator important?

The mediation of Christ signifies that He bridges the gap between mankind and God, as we are unable to enter God's presence due to our sinfulness. According to Hebrews 9:15, He is the mediator of the new covenant, meaning access to God is possible only through Him. Without Christ as our mediator, we stand condemned. His role ensures that our prayers and pleas can reach the Father, emphasizing the necessity of His intercession for us. It reassures believers that they have an advocate in heaven who completely represents and understands their plight.
