3. Sometimes it is the quick happy _knocking of joy_. Someone wrote to me the other day that he had had a great joy. All the darkness seemed now to have cleared away. He said: "I see my path in the light of GOD'S love." There was the quick knocking of joy, and CHRIST came in with the joy. The clearer knock of joy was the knocking of JESUS CHRIST. 4. Sometimes it is _some friend_ who comes into the life, some influence, perhaps a parish priest, who knocks at the door. Perhaps only too unwillingly at first you open the door, and you find that in the parish priest who comes you have found your best friend on earth, and he by his coming in brings CHRIST to you; he brings Him with him, and he leaves Him with you, if he is a faithful steward. If the parish priest is a faithful steward, he leads you to the Master. Then, perhaps, the sudden call comes. I have seen this happen to many young soldiers. I lately spent two months with those who were just going out--they are now in the trenches. They crowded in every evening to have a talk or they lay down on the ground and drank in every word at some Church Parade service. I could see, as I watched their faces, that they were hearing the call of their country to risk their lives, their all. It brought them near to JESUS CHRIST. In the knocking of their country's call JESUS CHRIST knocked, and I believe there are many fighting in the trenches now every day borne up by a faith they did not have until this summer--a belief in the immediate presence of their SAVIOUR with them. It would not have happened but for this sudden necessity of facing the ordeal of their lives. Is it possible that all these things, or some of them, have been happening to you--or something different that I have not mentioned--and you have never recognised it as yet as being what it is, JESUS CHRIST knocking at the door? Now what are you to do? What are any of us to do, for I am just one among you? It seems clear there are three things that we are bound to do, if this great miracle (and it is nothing else) is to take place. The first thing is to listen for and recognise the voice of JESUS CHRIST outside the door, that we may be ready and prepared to open the door. And do you not think that the reason that many of us never hear JESUS CHRIST'S voice is that we never listen for it, that we have no quiet time, that we have provided no time for meditation and prayer? We are too busy. We get up in the morning just in time to start off for our work; we never have this quiet time, or only a very few moments to think, in which the voice will be heard.
