This sermon explores Acts 12, where King Herod Agrippa I attempts to destroy the early church by executing James and imprisoning Peter. The message examines how the church responded with earnest prayer while Peter awaited execution, leading to his miraculous rescue by an angel. It contrasts Peter's humble trust in God with Herod's pride and ultimate judgment when he accepted worship as a god. The sermon covers the themes of prayer's power against earthly opposition, the danger of pride versus the blessing of humility, and how God's purposes cannot be stopped by human power. The message concludes with three practical applications: praying earnestly in difficult circumstances, humbling ourselves before God, and joining God's unstoppable mission.
