What is the significance of Jesus overcoming the devil?

The significance of Jesus overcoming the devil in His temptation is twofold: it demonstrates His authority as the Son of God and foreshadows His ultimate victory over sin and death through the cross. By resisting temptation and remaining sinless, Jesus qualifies as the perfect sacrifice, taking upon Himself the wrath that was due to sinners. Romans 16:20 assures believers that God will soon crush Satan under their feet. This victory is foundational for Christian hope, as it assures believers that through Christ, they share in the triumph over sin and the assurance of salvation.
