This sermon, delivered on Reformation Sunday, centers on the transformative power of persistent, bold prayer as modeled by Jesus in Luke 11:5–13, emphasizing that true spiritual vitality arises not from mere religious routine but from a deep, ongoing communion with God. Drawing from the Lord's Prayer and the parable of the friend at midnight, it teaches that prayer is not a transactional request but a confident, shameless pursuit of God's will, grounded in the Father's loving generosity. The passage underscores that God, far from being indifferent, delights in giving His children the Holy Spirit—the source of all spiritual blessing—when they ask, seek, and knock with faith and perseverance. The sermon connects theological understanding with practical devotion, asserting that genuine knowledge of God compels a life of prayer, and that a lack of prayer reveals a failure to truly value God's presence. Ultimately, the goal of prayer is not material gain but the glorification of God and the advancement of His kingdom through the Spirit's work in believers' lives.
