What does the Bible say about judgment and separation of believers and non-believers?

In Matthew 25:31-34, we see a profound picture of the final judgment. All people, regardless of their earthly lives, will stand before the Lord Jesus Christ, who will execute a just separation between believers and non-believers. The sheep, representing the elect, will be placed on the right hand, blessed by the Father to inherit the kingdom prepared for them from the foundation of the world. This separation illustrates God's sovereign choice in salvation, emphasizing that it is entirely His grace and mercy that makes us differ from those who are condemned.
