Zac Poonen warns about the prevalent deception in Christendom through false signs and wonders, echoing the warnings of Jesus and Paul regarding 'another Jesus,' 'another spirit,' and 'another gospel' that cater to earthly desires rather than leading to true repentance and holiness. He emphasizes the need for believers to discern the true nature of ministry by comparing preachers to Jesus, focusing on their objectives, attitudes, and approaches to healing. Poonen highlights that many modern preachers prioritize miracles and entertainment over the essential message of freedom from sin, which is the core of Jesus' mission. He explains that God allows deceivers to test the faith of His people, revealing the idols of money and entertainment that have infiltrated the church. Ultimately, Poonen calls for a return to the true gospel that leads to genuine holiness and a relationship with Christ.
