What does the Bible say about Christ's role as judge?

Scripture repeatedly affirms Christ’s role as the ultimate judge. In Isaiah 63, we see a prophetic picture of Jesus who will tread the winepress of God's wrath alone, signifying His authority in judgment. The Day of Judgment is a central theme in Revelation, where John speaks of the Son of Man reaping the harvest of the earth. This presents a picture of Christ executing divine judgment upon the ungodly, reinforcing that authority has been given to Him as the Son of Man to discern and separate believers from non-believers.
