Sermon: Luke 11:9-13 - Ask, Seek, Knock. When you come to the Lord in prayer, are you confident He is willing to answer your prayers? One of the greatest impediments to effective prayer is low confidence that prayer matters, that prayer is significant, or that God will answer the prayers of His people. So how can we gain such confidence? In this sermon, we wrap our series on prayer by studying Jesus' teaching about why the believer should have confidence in God's willingness to answer prayer.
