Zac Poonen emphasizes the power of prayer and praise in spiritual warfare, using King Jehoshaphat's example from 2 Chronicles 20. When faced with overwhelming enemies, Jehoshaphat led Judah in fasting and prayer, acknowledging their weakness and placing their trust in God. His declaration, 'Our eyes are on Thee,' exemplifies the faith needed to invite God's intervention, which resulted in victory through praise. Poonen warns against the extremes of emotional praise without holiness and serious living without joy, urging believers to embody both praise and holiness as they follow Christ. Ultimately, he encourages a faith-filled praise that acknowledges God's sovereignty, even amidst trials.
