How do we know that Jesus is coming to judge the living and the dead?

The promise of Jesus' return to judge the living and the dead is a central theme throughout the New Testament. Revelation 19 vividly depicts Christ's return and His authority to execute judgment. Verses 11-16 illustrate Christ as the King of kings and Lord of lords, underlining His sovereignty in dispensing justice. Additionally, in Matthew 25:31-32, Jesus explicitly states that He will return in glory and judge all nations, separating the righteous from the wicked. These passages, among others, affirm the reality of a coming judgment, encouraging believers to live in anticipation of that day and to proclaim the gospel in hopes of drawing others to repentance before it is too late.
