What does the Bible say about eternal judgment?

In Matthew 25:31-46, Jesus describes the final judgment where all nations will be gathered before Him. He will separate them as a shepherd separates sheep from goats, indicating a clear distinction between those who are His and those who are not. The righteous, symbolized by the sheep, will inherit the kingdom prepared for them since the foundation of the world, while the unrighteous, symbolized by the goats, will be cast into eternal punishment. This passage underscores the sovereignty of Christ as the ultimate judge and the certainty of divine judgment.
