How do we know that Christians are complete in Christ?

The completion of a believer in Christ is rooted in the doctrine of imputed righteousness; through faith in Jesus, believers are made perfect. This is reflected in the assertion that Job's uprightness illustrates the status of God's people through Christ’s righteousness. Scripture assures us that 'we are complete in Him' (Colossians 2:10) because Jesus fulfills the law's demands on our behalf. Thus, God's people are seen as righteous not through their actions but through faith in Christ who stands perfect before God.
