"The unity about which the Apostle is concerned here is produced and created by the Holy Spirit Himself. He alone can produce this unity; and it is He alone who does produce this unity. This is obviously a matter of fundamental importance. The Apostle makes it quite clear that this is a unity which you and I can never produce. He does not even ask us to do so, he does not call upon us to do so, he does not exhort us to do so. What he asks us to do is to be careful not to break the unity that is already there, and which has been produced and created by the Holy Spirit Himself. We are to maintain it, not create it. It is the unity of the Spirit. It is His work, it is something that He does in us. -Martin Loyd Jones on Keeping the Unity of the Spirit from Ephesians 4.
