How do we know Christ's victory over temptation is true?

The truth of Christ's victory over temptation is substantiated by His perfect obedience as the incarnate Son of God, who faced genuine trials and temptations. This victory is not only documented in the Gospels but is also an essential aspect of His role as the second Adam. Romans 5:19 establishes that through one man's disobedience, the many were made sinners; so by one man's obedience, the many will be made righteous. Therefore, Christ's triumph in overcoming temptation serves as a pivotal moment that not only confirms His nature as the sinless Savior but also embodies God's redemptive plan for humanity, fulfilling the threats posed by sin and death.
