How do we know Jesus' authority and power are true?

The authority of Jesus is unmistakably displayed in John 18:4-6 when He identifies Himself with the phrase 'I am,' causing those who came to arrest Him to falter and fall. This demonstrates not only His divine nature but also His sovereign control over the events surrounding His death. Additionally, His miracles throughout the Gospels serve as concrete evidence of His power. By asserting who He is, Jesus clearly conveys that He is not merely a victim of circumstance but the sovereign Lord who orchestrates the plan of redemption according to His will.
