Final Answer:
Christ will manifest as judge to the believer and the unbeliever through the final judgment. Believers will face a judgment of their works for rewards, while unbelievers will face a judgment leading to eternal separation from God.
Step-by-step explanation:
In Christian theology, the manifestation of Christ as judge is rooted in the biblical concept of the Final Judgment. According to Scripture, believers will undergo the "Judgment Seat of Christ," where their deeds as followers will be evaluated. This judgment, mentioned in 2 Corinthians 5:10, determines rewards and responsibilities in the eternal kingdom. Believers are not judged for salvation but for their faithful service and obedience. The calculation here lies in the assessment of one's actions and the resulting rewards or loss of rewards based on a divine standard.
Conversely, the unbelievers will face the "Great White Throne Judgment" (Revelation 20:11-15). This judgment is distinct from the Judgment Seat of Christ and is reserved for those who rejected Christ. The calculation in this judgment involves the evaluation of their rejection of salvation, leading to eternal separation from God. The consequences are dire, as it involves an eternal separation from God's presence, marked by a lake of fire. This dual judgment underscores the theological understanding that Christ, in his role as judge, ensures both justice and righteousness.
In summary, the manifestation of Christ as judge involves distinct judgments for believers and unbelievers. The calculations revolve around the deeds of believers for rewards and the rejection of salvation by unbelievers, leading to eternal separation. This theological framework emphasizes divine justice and the accountability of individuals in the afterlife.
