What will happen at the final judgment according to the Bible?

The final judgment marks the culmination of God’s plan when all people will be resurrected. This is clearly laid out in 1 Corinthians 15:22-24, where all are made alive in Christ, followed by the end when He delivers the kingdom to God the Father. This judgment will see the faithful rewarded with eternal life while those who rejected God's grace face eternal separation from Him. Revelation 21 presents a stark contrast between the new creation for the redeemed and the final fate of the unrepentant. This event underscores the significance of Christ's reign as He ensures justice and establishes His everlasting kingdom.
