Why is understanding the delusion important for Christians?

Recognizing the delusion is crucial for Christians because it reveals how easily one can become ensnared by self-righteousness. This fundamental misunderstanding can lead to spiritual blindness, where believers fail to grasp the fullness of God's grace and the finished work of Christ. The Apostle Paul warns against this in 2 Corinthians 3, where he contrasts the ministry of the Spirit with the deadly veil of the law that promotes works righteousness (2 Corinthians 3:14). Understanding this helps believers rely solely on Christ for salvation and sanctification, leading to true freedom and transformation.
