What does the Bible say about the judgment at the end of the world?

Scripture clearly indicates that a final judgment awaits, where God will definitively separate the righteous from the wicked. In Matthew 13:39-42, Jesus explains that the harvest at the end of the world will involve angels gathering the tares (the wicked) to be cast into the furnace of fire while the righteous will shine in the Kingdom of their Father. This illustrates the seriousness of rejecting Christ and the eternal consequences of sin. Believers are reminded that their salvation through Christ grants them assurance of eternal life, as well as their responsibility to share the Gospel as they wait for His return.
