I have spoken so often in these passages already on the subject of work, that but little remains to be said. And yet there are so many kinds of work, and hard work too, that we can do on earth, that it seems as though we could never get to the end of them. There are, for instance, home work, warfare work, praying work, and a great many other kinds of work, of which it would take too long to speak now. Of some of these I have spoken already in this book, but I want to say a few words about _warfare work_ in this chapter. Warfare work is perhaps the hardest kind of work of all, because it is work of the spirit. It is a work that must be always going on, while we live here; so long as Satan lives to tempt man to sin, man must war against it. In the sixth chapter of S. John we read in the 28th verse, "Jesus said unto them, this is the work of God that ye believe on Him, whom He hath sent." It is no easy thing to believe; nay, it is very hard to believe simply in Jesus Christ; and yet in the above passage He Himself speaks of it as the work of all others, which is to be done for God. When our hearts get crusted over with sin and selfishness, it is no easy matter to take again the heart of a little child and simply believe our Father’s word; and yet this is needful work for His children. But besides this inner struggle, there is another that affects more our outward life. All have a besetting sin to fight against--drunkenness, lust, or such like. Very different, however, are the ways in which this warfare is waged. Some struggle because they can’t help it, and are like "the dumb driven cattle"; others are so feeble that they soon "By the roadside fall and perish, Weary with the march of life." Others try to conceal, even from themselves, that they have a conflict to maintain. It is the Christian only, who going forth in the strength of Another, can hope to work joyfully and successfully.
