What does it mean to be called righteous in Christ?

Being called righteous in Christ signifies that believers are justified before God through faith. This righteousness is not based on personal merit but solely on Christ's sacrificial death and resurrection. As noted in Romans 8:1, 'There is therefore now no condemnation for those who are in Christ Jesus.' This notable change in status highlights the transformative effect of grace whereby the believer is cleansed and made acceptable before God. The assurance in Isaiah 3:10 reiterates that those who have been made righteous by Christ can confidently affirm, 'It shall be well with him,' reflecting the peace and security that comes from being united with Christ in His righteousness.
