Pastor Ryan Deas teaches on biblical fasting as a New-Covenant practice that grows faith and breaks unbelief. From Matthew 9:14–17, Jesus ties fasting to “new wine in new wineskins,” calling us to a renewed mindset, not legalism. In Matthew 17:14–21, Jesus rebukes unbelief and says, “this kind goes not out but by prayer and fasting.” With Isaiah 58:3–12, John 5:39, and Romans 8:1, the message sets fasting in grace, urges humble obedience, and calls believers to pray, hear God’s Word, and walk in Spirit-empowered authority.
