According to the Book of Revelation (chapter 20), all human beings who are not found in the Book of Life will be brought before God for judgment. The Book of Life represents the list of those whose sins have been forgiven through faith in Jesus Christ. Those whose names are not in the Book of Life will be judged based on their actions, deeds, and words during their lifetime.
The standard for judgment is the law of God, as revealed in the Bible, which encompasses all moral principles and commandments. The Bible states that all people have fallen short of God's perfect standard and are therefore in need of salvation and forgiveness through Jesus Christ.
Regarding Christians, it is important to understand that salvation in Christianity is not based on our works or achievements but solely on the grace and mercy of God through faith in Jesus Christ. However, Christians are still accountable for their choices and actions and are called to live a life of obedience and righteousness.
While Christians are saved from eternal condemnation through faith in Christ, they will still face a type of judgment or evaluation before God called the Judgment Seat of Christ, which is distinct from the Great White Throne Judgment. This assessment focuses on evaluating the lives of believers and their stewardship of God's resources and gifts.
In summary, the Great White Throne Judgment is portrayed in Revelation as a judgment according to works for those whose names are not found in the Book of Life. This judgment serves as a reminder that all human beings are accountable for their deeds and choices and will ultimately face God's evaluation and justice.
