Why is it important for Christians to understand their dual nature?

Recognizing that believers possess both a holy nature and a sinful nature clarifies the Christian experience of struggle against sin. It emphasizes that while believers are made new in Christ, they still wrestle with their old sinful nature. This understanding fosters humility, as it reveals the believer's complete reliance on the grace of God for sanctification and salvation. It also assures believers that their struggles are a part of the Christian life, encouraging them to seek Christ as the answer to their sinfulness. The dual nature underscores the believer's need for continual growth in grace and reliance on the Holy Spirit.
