I have already anticipated, fragmentarily, nearly all that I could have said here in a more systematic form. All gladness has something to do with our efficiency; for it is the prerogative of man that his force comes from his mind, and not from his body. That old song about a sad heart tiring in a mile, is as true in regard to the Gospel, and the works of Christian people, as in any other case. If we have hearts full of light, and souls at rest in Christ, and the wealth and blessedness of a tranquil gladness lying there, and rifling our being; work will be easy, endurance will be easy, sorrow will be bearable, trials will not be so very hard, and above all temptations we shall be lifted, and set upon a rock. If the soul is full, and full of joy, what side of it will be exposed to the assault of any temptation? If the appeal be to fear, the gladness that is there is an answer. If the appeal be to passion, desire, wish for pleasure of any sort, there is no need for any more, the heart is full. And so the gladness which rests in Christ will be a gladness which will fit us for all service and for all endurance, which will be unbroken by any sorrow, and, like the magic shield of the old legends, invisible, impenetrable, in its crystalline purity will stand before the tempted heart, and will repel all the fiery darts of the wicked.'
The joy of the Lord is your strength,' my brother! Nothing else is. No vehement resolutions, no sense of his own sinfulness, nor even contrite remembrance of past failures, ever yet made a man strong. It made him weak that he might become strong, and when it had done that it had done its work. For strength there must be hope, for strength there must be joy. If the arm is to smite with vigour, it must smite at the bidding of a calm and light heart. Christian work is of such a sort as that the most dangerous opponent to it is simple despondency and simple sorrow. The joy of the Lord is your strength.'
Well, then! there are two questions: How comes it that so much of the world's joy is weakness? and how comes it that so much of the world's notion of religion is gloom and sadness? Answer them for yourselves, and remember: you are weak unless you are glad; you are not glad and strong unless your faith and hope are fixed in Christ, and unless you are working from and not towards the sense of pardon, from and not towards the conviction of acceptance with God!
