As I have said, the urgency of the command indicates both its importance and its difficulty. It is important that professing Christians should be glad Christians (with the joy that is drawn from Jesus Christ, of course, I mean), because they thereby become walking advertisements and living witnesses for Him. A gloomy, melancholy, professing Christian is a poor recommendation of his faith. If you want to adorn the doctrine of Christ' you will do it a great deal more by a bright face, that speaks of a calm heart, calm because filled with Christ, than by many more ambitious efforts. This gladness is important because, without it, there will be little good work done, and little progress made. It is important, surely, for ourselves, for it can be no small matter that we should be able to have travelling with us all through the desert that mystical rock which follows with its streams of water, and ever provides for in the joys that we need. In every aspect, whether as regards men who take their notions of Christ and of Christianity, a great deal more from the concrete examples of both in human lives than from books and sermons, or from the Bible itself--or as regards the work which we have to do, or as regards our own inward life, it is all-important that we should have that close union with Jesus Christ which cannot but result in pure and holy gladness.
But the difficulty, as well as the importance, of the obligation, are expressed by the stringent repetition of the commandment,' And again I say, Rejoice.' when objections arise, when difficulties present themselves, I repeat the commandment again, in the teeth of them all; and I know what I mean when I am saying it. Thus, thought Paul, we need to make a definite effort to keep ourselves in touch with Jesus Christ, or else gladness, and a great deal besides, will fade away from our grasp.
And there are two things that you have to do if you would obey the commandment. The one is the direct effort at fostering and making continuous your fellowship with Jesus Christ, through your life; and the other is looking out for the bright bits in your life, and making sure that you do not sullenly and foolishly, perhaps with vain regrets after vanished blessings, or perhaps with vain murmurings about unattained good, obscure to your sight the mercies that you have, and so cheat yourselves of the occasions for thankfulness and joy. There are people who, if there be ever such a little bit. of a fleecy film of cloud low down on their horizon, can see nothing of the sparkling blue arch above them for looking at that, and who behave as if the whole sky was one roof of doleful grey. Do not you do that I There is always enough to be thankful for. Lay hold of Christ, and be sure that you open your eyes to His gifts.
Surely, dear friends, if there be offered to us, as there is, a gladness which is perfect in the two points in which all other gladness fails, it is wise for us to take it. The commonplace which all men believe, and most men neglect, is that nothing short of an infinite Person can fill a finite soul. And if we look for our joys anywhere but to Jesus Christ, there will always be some bit of our nature which, like the sulky elder brother in the parable, will scowl at the music and dancing, and refuse to come in. All earthly joys are transient as well as partial. Is it not better that we should have gladness that will last as long as we do, that we can hold in our dying hands, like a flower clasped in some cold palm laid in the coffin, that we shall find again when we have crossed the bar, that will grow and brighten and broaden for evermore? My joy shall remain full.
