Christian men, the joy of the Lord is a duty. It is so because, as we have seen, it is the natural effect of faith, because we can do much to regulate our emotions directly, and much more to determine them by determining what set of thoughts shall engage us. A wise and strong faith is our duty. To keep our emotional nature well under control of reason and will is our duty. To lose thoughts of ourselves in God's truth about Himself is our duty. If we do these things, we cannot fail to have Christ's joy remaining in us, and making ours full. If we have not that blessed possession abiding with us, which He lived and died to give us, there is something wrong in us somewhere. It seems to me that this is a truth which we have great need, my friends, to lay to heart. It is of no great consequence that we should practically confute the impotent old sneer about religion as being a gloomy thing. One does not need to mind much what some people say on that matter. The world would call 'the joy of the Lord' gloom, just as much as it calls 'godly sorrow' gloom. But we are losing for ourselves a power and an energy of which we have no conception, unless we feel that joy is a duty, and unless we believe that not to be joyful in the Lord is, therefore, more than a misfortune, it is a fault. I do not forget that the comparative absence of this happy, peaceful sense of acceptance, harmony, oneness with God, springs sometimes from temperament, and depends on our natural disposition. Of course the natural character determines to a large extent the perspective of our conceptions of Christian truth, and the colouring of our inner religious life. I do not mean to say, for a moment, that there is one uniform type to which all must be conformed, or they sin. There is indeed one type, the perfect manhood of Jesus, but it is all comprehensive, and each variety of our fragmentary manhood finds its own perfecting, and not its transmutation to another fashion of man, in being conformed to Him. Some of us are naturally fainthearted, timid, sceptical of any success, grave, melancholy, or hard to stir to any emotion. To such there will be an added difficulty in making quiet confident joy any very familiar guest in their home or in their place of prayer. But even such should remember that the 'powers of the world to come,' the energies of the Gospel, are given to us for the very express purpose of overcoming, as well as of hallowing, natural dispositions. If it be our duty to rejoice in the Lord, it is no sufficient excuse to urge for not responding to the reiterated call, 'I myself am disposed to sadness.'
