Many of you know that probably the words 'in Ephesus' are no part of the original text of this epistle, which was apparently a circular letter, in which the designation of the various churches to which it was sent was left blank, to be filled in with the name of each little community to which Paul's messenger from Rome carried it. The copy from which our text was taken had probably been delivered at Ephesus; and, at any rate, one of the copies would go there. What was Ephesus? Satan's very headquarters and seat in Asia Minor, a focus of idolatry, superstition, wealth, luxury springing from commerce, and moral corruption. 'Great is Diana of the Ephesians.' The books of Ephesus were a synonym for magical books. Many of us know how rotten to the core the society of that great city was. And there, on the dunghill, was this little garden of fragrant and flowering plants. They were 'saints in Christ Jesus,' though they were 'saints in Ephesus.' Never mind about surroundings. It is possible for us to keep ourselves in the love of God, and in the fellowship of His Son wherever we are, and whatever may lie around us. You and I have too to live in a big, wicked city, and to work out our religion in a society honeycombed with corruption, because of commerce and other influences. Do not let us forget that these people whom Paul called 'saints' and 'faithful' had a harder fight to wage than we have, with less to hearten and strengthen them in it. Only remember if the 'saints in Ephesus' are to be 'in Christ,' they need to keep themselves very straight up. The carbonic acid gas is heavy and goes down to the bottom of the cave, and if a man will walk bolt upright, he will keep his nostrils above it; but if he stoops, he will get down into it. Walk straight up, with your head erect, looking to the Master, and your respiratory organs will be above the poison. If we are to _be_ in Christ when we are in Ephesus, we need to keep ourselves separate and faithful, and to _keep ourselves_ in Christ. If the diver comes out of the diving-bell he is drowned. If he keeps inside its crystal walls he may be on the bottom of the ocean, but he is dry and safe. Keep in the fortress by loyal faith, by humble realisation of His presence, by continual effort, and 'nothing shall by any means harm you,' but 'your lives shall be holy, being hid with Christ in God.' 'ALL SPIRITUAL BLESSINGS' 'Blessed be God ... who hath blessed us with all spiritual blessings in heavenly places in Christ.'--Eph. i. 3.
