Zac Poonen emphasizes the importance of living and serving in a Christ-like manner, drawing from Paul's farewell to the elders in Ephesus. He highlights that despite the miracles and sermons Paul performed, it was his humble lifestyle and hard work that left a lasting impact on the church. Poonen challenges modern ministers to reflect on whether they are remembered for their preaching or their Christ-like character, urging them to serve without seeking personal gain. He warns against the prevalence of self-serving ministers and calls for a return to the simplicity and compassion exemplified by Jesus. Ultimately, he encourages all believers to let their ministries flow from a life that radiates the glory of Christ.
