What is the significance of Jesus' dual nature as both God and man?

The dual nature of Jesus—being fully God and fully man—is crucial in the context of salvation. This doctrine confirms that Jesus is the mediator between God and man, which is vital given that only someone who is both can adequately represent humanity before God and satisfy divine justice. Hebrews 4:15 notes that He was tempted in every way, just as we are, yet without sin, allowing Him to empathize with our weaknesses. His divine nature enabled Him to be the perfect sacrifice, unblemished and holy, while His human nature equipped Him to bear the sins of His people. This unique union means He is our great high priest who advocates for us, making possible the relationship with God that sin had severed. Thus, understanding Jesus as God-man enriches our appreciation for His sacrificial love and the fullness of our salvation.
