Zac Poonen emphasizes the need for a 'Daniel-ministry' in today's world, highlighting how Daniel's unwavering commitment to God inspired others like Hananiah, Mishael, and Azariah to stand firm in their faith. He contrasts this with the 'Lucifer-ministry,' which leads to rebellion and division within the church, allowing God to expose and purify the Body of Christ. Poonen calls for individuals to take a stand for righteousness, encouraging believers to lead by example rather than merely preaching. He stresses that true leadership in faith involves guiding others towards righteousness through both words and actions. Ultimately, the sermon challenges listeners to choose which ministry they will embody in their lives.
