Ephesians 6:14 — Modern teaching says that what a person believes matters little if they live a good life. In this sermon on Ephesians 6:14 titled “The Only Authority,” Dr. Martyn Lloyd-Jones shares that this attitude is the exact opposite of the exhortation from the apostle Paul to “put on” truth. Dr. Lloyd-Jones boldly proclaims that putting on truth will put the Christian at odds with the world. Doctrine will divide while the world will fight to put unity above truth. Paul said that the Christian must hold on to truth, for without it they are already spiritually defeated. The great question today is the question of authority. Modern authority is human reason based upon modern knowledge but that is inadequate. Human minds are too finite to be trusted as ultimate authority. Authority cannot be based upon feelings either because they are so variable and unreliable. It also cannot be the pragmatic test of what makes one feel better or live better. That is entirely subjective. Authority cannot be reason or feeling. The Christian must preach the gospel faithfully to warn people and to bring them to the knowledge of truth as it is in Christ Jesus.
