Zac Poonen emphasizes the transformative nature of the new covenant, highlighting that while John the Baptist was the greatest prophet of the old covenant, even the least in the new covenant can achieve greater heights. He explains that Jesus serves as our ultimate example of servanthood, calling us to lead others towards the Divine nature rather than merely ruling over them. Poonen stresses the importance of personal sanctification and the necessity for leaders to be examples in speech, love, faith, and purity, urging that true ministry comes from overcoming personal trials and leading others to do the same. He warns against the dangers of seeking human approval and emphasizes the need for humility, likening true leadership to that of a child. Ultimately, he calls for a return to the essence of servanthood as bondslaves of Christ, free from the desire for material gain or recognition.
