In this sermon on praying in the Spirit from Ephesians 6:18, Dr. Martin Lloyd-Jones guides the listener through this careful study of how Christians are to pray. The blood of Jesus, His death, and the resurrection of Jesus Christ gives His people unhindered access to the Father. But that open access to God in prayer is not an invitation to be casual, flippant, or fill prayers with meaningless repetition. Christians need the Holy Spirit's guidance to teach them how to pray. The spiritual battles of life, the weakness of the flesh, and the need for intercession requires careful attention to one’s communication with their king. Prayer that glorifies God and maximizes the spiritual life is prayer that is filled with reverence and respect for the Father who loves and is always ready to hear the voice of His children.
