The Apostle, in an earlier part of this same letter, defines for us what that hope is, which thus is the secret of perpetual gladness, when he speaks about 'rejoicing in hope of the glory of God.' Yes, it is that great, supreme, calm, far off, absolutely certain prospect of being gathered into the divine glory, and walking there, like the three in the fiery furnace, unconsumed and at ease; it is that hope that will triumph over temperament, and over all occasions for melancholy, and will breathe into our life a perpetual gladness. Brethren, is it not strange and sad that with such a treasure by our sides we should consent to live such poor lives as we do?
But remember, although I cannot say to myself, 'Now I will be glad,' and cannot attain to joy by a movement of the will or direct effort, although it is of no use to say to a man--which is all that the world can ever say to him--'Cheer up and be glad,' whilst you do not alter the facts that make him sad, there is a way by which we can bring about feelings of gladness or of gloom. It is just this--we can choose what we will look at. If you prefer to occupy your mind with the troubles, losses, disappointments, hard work, blighted hopes of this poor sin-ridden world, of course sadness will come over you often, and a general grey tone will be the usual tone of your lives, as it is of the lives of many of us, broken only by occasional bursts of foolish mirth and empty laughter. But if you choose to turn away from all these, and instead of the dim, dismal, hard present, to sun yourselves in the light of the yet unrisen sun, which you can do, then, having rightly chosen the subjects to think about, the feeling will come as a matter of course. You cannot make yourselves glad by, as it were, laying hold of yourselves and lifting yourselves into gladness, but you can rule the direction of your thoughts, and so can bring around you summer in the midst of winter, by steadily contemplating the facts--and they are present facts, though we talk about them collectively as 'the future'--the facts on which all Christian gladness ought to be based. We can carry our own atmosphere with us; like the people in Italy, who in frosty weather will be seen sitting in the market-place by their stalls with a dish of embers, which they grasp in their hands, and so make themselves comfortably warm on the bitterest day. You can bring a reasonable degree of warmth into the coldest weather, if you will lay hold of the vessel in which the fire is, and keep it in your hand and close to your heart. Choose what you think about, and feelings will follow thoughts.
But it needs very distinct and continuous effort for a man to keep this great source of Christian joy clear before him. We are like the dwellers in some island of the sea, who, in some conditions of the atmosphere, can catch sight of the gleaming mountain-tops on the mainland across the stormy channel between. But thick days, with a heavy atmosphere and much mist, are very frequent in our latitude, and then all the distant hills are blotted out, and we see nothing but the cold grey sea, breaking on the cold, grey stones. Still, you can scatter the mist if you will. You can make the atmosphere bright; and it is worth an effort to bring clear before us, and to keep high above the mists that cling to the low levels, the great vision which will make us glad. Brethren, I believe that one great source of the weakness of average Christianity amongst us to-day is the dimness into which so many of us have let the hope of the glory of God pass in our hearts. So I beg you to lay to heart this first commandment, and to rejoice in hope.
