How do we know Jesus is the judge of mankind?

The authority of Jesus as the judge of mankind is firmly rooted in the Scriptures. In John 5:22, it states that the Father has given all judgment to the Son so that the Son may receive honor just as the Father does. This clearly establishes that Jesus, the Lamb of God who came to take away the sins of the world, is also the appointed judge who will execute justice. His dual role emphasizes that while He offers salvation and grace, He will also hold humanity accountable on the day of judgment. Thus, understanding Jesus as the judge is crucial for believers as it reinforces the need to live in alignment with God's will and to trust in His sovereignty.
