Keith Simons teaches on Psalm 107, emphasizing the four testimonies of God's rescue for His people. He highlights God's enduring mercy and goodness, illustrating how He delivers those in distress, whether they are wandering in the wilderness, imprisoned, afflicted by their own foolishness, or caught in a storm at sea. Each testimony culminates in a call to praise the Lord for His wonderful works and loving kindness. Simons encourages believers to recognize and share their own testimonies of God's faithfulness and deliverance.
