Why is it important for Christians to understand justification and sanctification?

Grasping the doctrines of justification and sanctification is crucial for Christians as it directs their understanding of salvation and righteousness. Justification assures believers that their right standing before God is solely based on Christ's finished work, alleviating any burdens of self-justification or reliance on personal efforts. This assurance leads to true peace and freedom in the believer's walk. Sanctification, however, reminds Christians of their continual need for grace as they navigate the Christian life, emphasizing that holiness cannot be achieved through the law or human effort. Instead, it is a result of the Holy Spirit's work in their lives, encouraging believers to remain dependent on Christ for both their justification and their ongoing holiness, as stated in Galatians 2:21.
