How can Christians be assured of their justification?

Christians can be assured of their justification by placing their faith solely in Christ's perfect righteousness. The gospel teaches that our worthiness before God is not based on our works but on the finished work of Christ. In Colossians 1:22, it says that through Christ, we are presented 'holy and blameless and above reproach in His sight.' This assurance is amplified by the promise in Romans 8:1 that there is now no condemnation for those who are in Christ Jesus, underscoring that our justification rests in His faithfulness, not our failings.
