Why is self-ignorance dangerous for Christians?

In the account of the rich young ruler, self-ignorance is highlighted as one of the greatest obstacles to true spiritual understanding. Jesus points out the commandments to reveal the man's blindness to his own sinfulness. This scenario reveals that many people lack awareness of their spiritual condition, believing themselves righteous without realizing the depth of God's law. To awaken from this spiritual slumber, one must be enlightened by the Holy Spirit to recognize the need for grace and repentance, as true understanding of one's sinful state is vital for salvation.
