He had been pouring out his soul on the subject of the true Christian life--the deep sources from which it springs, the great channels in which it runs, the magnificent conditions of Christ's kingdom under which it becomes possible and is accomplished. But yet, another order of things crosses all this. It is the incessant detail of human life on earth, with its pettiness and superficiality, and yet with its inevitable hold upon us all. How much we are at the mercy of it! How hard to keep quite true to the grand music of the gospel we believe, amid the multifarious patter of the incidents of life, playing on the surface only, but on the sensitive surface of our being. The case of Euodia and Syntyche was itself but an illustration, of the commonest kind, of the liability of believing lives to be swayed and marred in this way. For all these little things claim attention; they assume a magnitude that does not belong to them, and they take a place to which they have no right. Can anything be said to help us to some prevailing mood, in which we shall be likely to take the right attitude towards these elements of life, and, at the same time, to keep due touch with the springs of our spiritual welfare? The Apostle reverts to the significant "good-bye" which was heard at the beginning of the third chapter. "Rejoice," "Be of good cheer," was the usual farewell salute. He had begun to use it, in the third chapter, with an emphasis on the native signification of the word. Now he resumes it more emphatically still, for here he finds the keynote which he wants: "Rejoice in the Lord alway; again I will say it, Rejoice." If joy be possible, it would seem to need no great persuasion to induce men to embrace it. But, as a matter of fact, Christians fail greatly here. In the Old Testament there are abundant exhortations to Israel to rejoice in the Lord: the Lord being Jehovah, without further distinction or limitation; and the ground of rejoicing being His revealed character, especially His mercy and His truth, and the fact that He is Israel's God. Here the Lord is our Lord Jesus, in whom the Father is both known and found. Now, to rejoice in Him is, and should be recognised as being, for believers, the most direct inference from their faith. For if this Lord be what the believer holds Him to be, then there is more in Christ to make him glad, than there can be in anything whatever to make him sorry. This applies even to remembered sin; for where sin abounded, grace doth much more abound. If indeed the joy be really in the Lord, it will be found to agree well with humility and penitence, as well as with diligence and patience; for all these things, and whatever should accompany them, come naturally from faith in Christ. But not the less, joy should have its place and its exercise.
