How do we know Christ judges His people now?

Christ's judgment is manifest through the preaching of the gospel, as outlined in Psalm 50. This psalm emphasizes that Christ gathers His saints and judges them through His Word, discerning the true believers from the false. In verse 5, God calls for His people to come together, indicating that the gospel serves as the means by which He evaluates the hearts and lives of professing believers. Each person's response to this gospel will determine their standing before God in the final judgment, highlighting the essential nature of faith in Christ as our righteousness.
