Zac Poonen emphasizes the danger of self-sufficiency and ignorance of one's spiritual wretchedness, as illustrated by the elder in Laodicea who believed he was rich and in need of nothing. Unlike the apostle Paul, who recognized his own wretchedness and lived in the light of God, the Laodicean elder was blind to his true condition, leading to a lukewarm and carnal life. Poonen warns that gifted preachers can fall into arrogance, speaking from a place of self-sufficiency rather than humility, which does not build the Body of Christ. He stresses that true spiritual growth comes from recognizing our need for God and maintaining a humble spirit. Ultimately, it is the poor in spirit who can genuinely contribute to the kingdom of God.

John Wesley emphasizes the importance of self-awareness and humility in his sermon 'Know Yourself.' He contrasts the self-righteousness of the Pharisee with the genuine repentance of the tax collector, urging listeners to reflect on their own lives and recognize their need for God's mercy. Wesley highlights that many outside of prison may be just as sinful as those incarcerated, yet they often fail to see their need for a Savior. He encourages honest introspection and the question, 'How goes it with your soul?' to foster a deeper understanding of oneself in relation to God.
