How are Christians judged by God?

According to historic Reformed theology, Christians are judged based on their union with Christ. When God looks at believers, He sees Christ's righteousness instead of their sins. This means that they are judged as perfect or '100%' because Christ fulfilled the law on their behalf. The sacrifice of Jesus ensured that all their sins were accounted for, and therefore, the judgment has already been satisfied in Him. This understanding gives believers confidence and assurance before God, knowing that they are accepted in the beloved.
