How do we know that Jesus is the true mediator?

The assurance that Jesus is the true mediator stems from His dual nature as both fully God and fully man. Scriptures like 1 John 5:7 affirm the unity of the Father, Son, and Holy Spirit, indicating Jesus's divine authority. Furthermore, His life, death, and resurrection fulfill all the requirements for redemption; He paid the ransom for His people with His own blood (Acts 20:28). Without any other mediator being able to bridge this divine gap, the qualification of Jesus as the one mediator is unparalleled. His intercessory role is to be emphasized, as He ever lives to make intercession for His people (Hebrews 7:25). This points to His continuing involvement in our lives and underlines His capability to mediate effectively between us and the Father.
