This week, we begin a brand-new series at Grant Church called God’s Firefighters, led by Professor Pierre Gilbert, PhD. In this opening message from Isaiah 1:10-20, Dr. Gilbert unpacks one of the classic passages that reflects the heart of the prophetic message.Together, we’ll examine why prophets were sent, the consequences of Israel’s sin, and how divine warnings—such as C. S. Lewis’ reminder that “pain is God’s megaphone”—point us back to Him. We’ll also wrestle with God’s call to justice, His judgment, and the dangers of idolatry, all leading to the prophets’ ultimate invitation: a call to conversion.Topics: Old Testament prophets, Isaiah 1, sin and consequences, justice and idolatry, God’s call to repentanceScripture: Isaiah 1:10-20Speaker: Professor Pierre Gilbert, PhDTags: Isaiah sermon, Old Testament prophets, prophetic message, call to repentance, God’s justice, Grant ChurchDon’t forget to like, subscribe, and share so more people can discover the power of God’s Word today!Watch the complete service: https://youtube.com/live/CpdwS6al8mIWe would love to hear from you!Instagram: @grantchurch.caFacebook: grantchurch.caEngage on our website: https://www.grantchurch.ca
