The sermon explored the spiritual authority we've been given as believers through the keys of the kingdom that Jesus promised in Matthew 16:19. Through the story of King Jehoshaphat in 2 Chronicles 20, we saw how God's people faced an impossible enemy, the Moabites and Ammonites, and discovered that victory comes not through our own strength, but through prayer, fasting, worship, and obedience to God's word. Just as Jehoshaphat sent the worship team out before the army, we too must learn to use the spiritual keys God has given us: prayer that opens doors, fasting that breaks strongholds, and praise that defeats the enemy. This message has profound implications for how we face the challenges in our families, finances, relationships, and personal battles that refuse to go away.
