Why is the concept of being justified important for Christians?

The concept of justification is vital for Christians as it affirms that they are declared righteous before God, not based on their own merits, but solely on Christ's sacrifice. This assurance of right standing is rooted in faith, as seen in Romans 5:1, which states that 'having been justified by faith, we have peace with God through our Lord Jesus Christ.' Justification impacts every aspect of the believer's life, freeing them from guilt and enabling a relationship with God that is no longer based on fear of condemnation. Additionally, it sets the foundation for sanctification, as justified individuals are empowered to live righteous lives through the Holy Spirit.
