Zac Poonen addresses the jealousy of the Pharisees towards Jesus, who performed miracles that they could not, highlighting their inability to rejoice in God's work due to their pride and sectarianism. He emphasizes that true miracles occur where the gospel is preached for the first time, often through ordinary believers, and warns against the counterfeit miracles seen in modern times. Poonen encourages believers to trust God for real miracles and to pray for healing, reminding them of their privileges as children of God. He also stresses the importance of giving glory to God for any miracles that occur, to avoid falling into the same trap of pride as the Pharisees.
