Then, when we have heard the voice and recognised the knock, the next thing to do is to open the door. How simple that sounds, does it not? and how difficult it often is! Picture some who have had the door of their souls closed tightly for years. You have to prise the door open, and you have to break down the fixed habits of the man who has never prayed except for a few moments or two in his life; how hard he finds it to reverse the habits of a lifetime! Someone who has an old quarrel, through jealousy or something else, with another worker--how hard it is to forgive and begin all over again! But it has got to be done, the door has to be prised or forced, because if CHRIST is to come in we have to open the door--that is our part in it--and CHRIST _will_ come in. And if only we realised how eager He is to come in, and what a power He has to change the heart and control the thoughts and purify the conscience, we should all want Him to come, and we should not spare any time and trouble to get the door open. And when He has come in, notice this wonderful phrase: "I will sup with him, and he with Me." He does not come in as a transient guest to stay for a little while, and go away, but He comes on a permanent visit, to take up His permanent residence. And although we should not have dared to use the words ourselves, the words "I will sup with him, and he with Me," describe the most delightful friendship. Do you desire His presence? How often do you come to Holy Communion, how carefully do you prepare for the great gift of the presence of JESUS CHRIST in your soul? Why, I would press this on you, that the supping with JESUS CHRIST and He with you which takes place in the Holy Communion is the most glorious moment of your whole day. The first Christians never thought of spending Sunday without going first to Holy Communion. It was the special service on the Lord's Day. It may be that some of you who used to be regular have drifted away from this way of receiving the presence of CHRIST into the soul. We know no better way for cherishing the presence of CHRIST in the soul than being regular at Communion. The humblest communicant comes away from his Communion with the thought: "CHRIST lives in me; I live, yet not I, but CHRIST liveth in me." Will you, then, take from me these three thoughts, Listening, Opening, and Cherishing the Presence: Devotion, Consecration, Communion? And if you do, I tell you what will happen to your deanery. It will gradually become the most Christian fellowship in London. You will be drawn to one another in a way in which you never have been before. We want more unity in every deanery, so that the parishes may take an interest in one another, and that all Church gatherings may be keen and well attended as by a band of brothers and sisters.
