In this sermon on Ephesians 3:14–15 titled “Praying to the Father,” Dr. Martyn Lloyd-Jones stresses the importance of prayer and its practice from Paul’s example. Dr. Lloyd-Jones discusses prayer in three important principles from this passage. First, it is important that the apostle Paul is praying for the Ephesians. Even in the midst of his imprisonment he is praying. Prayer is a vital necessity for every believer in every circumstance. Second, Dr. Lloyd-Jones looks at the manner in which Paul is praying. He is praying with reverence. Though he has just mentioned earlier in the chapter that one can come to God in prayer with boldness, he shows here a heart of humility in how he approaches God in prayer. The Christian should be careful to evaluate how they come to God in prayer. It is not necessarily about the outward posture, but does the inward posture show humility in spirit before the Holy God when He is approached in prayer? Lastly, Dr. Lloyd-Jones points out the importance for Paul’s description of God here in the passage. He speaks of Him as being the Father of all. Jews and Gentiles alike are now fellow heirs, children of God, bearing the name of God and addressing Him as their Father.
