How do we know that Jesus has overcome the world?

Jesus's declaration that He has overcome the world is evidenced by His sacrificial death on the cross and His victorious resurrection. Despite facing betrayal and crucifixion, His mission was to triumph over sin and death. Romans 8:37 reassures believers, saying, 'We are more than conquerors through Him who loved us.' The certainty of His victory is foundational for the Christian faith, emphasizing that our trials have been triumphed over by Christ's work, offering peace to those who are in Him.
