Zac Poonen emphasizes the necessity of total dependence on the Holy Spirit for a new covenant servant, contrasting the barren life of self-sufficiency with the fruitful life of reliance on God. He illustrates that prayer is essential for expressing this dependence, and that true faith is demonstrated through facing challenges and trusting God to overcome them. Poonen warns against the dangers of pride and self-confidence, which hinder spiritual growth and effectiveness in ministry. He encourages believers to seek the anointing of the Holy Spirit, as it is through this empowerment that they can serve others and fulfill God's purposes. Ultimately, he calls for a humble, faith-filled approach to ministry that prioritizes God's power over human ability.
