What does the Bible say about judgment day?

According to Revelation 20:11-15, judgment day is depicted as a great white throne where all the dead will stand before God. They will be judged based on their works recorded in books. This judgment reveals that all men fall short of God's glory and deserve eternal separation from Him. The scriptures make clear that the works of man, whether deemed good or bad, cannot save him. The key factor determining salvation is whether one's name is written in the Book of Life, which signifies being saved by the grace of God through faith in Christ alone.
