The Banner was the symbol of the cause for which an army fought, or the cognizance of the king or commander whom it followed. So Moses, by that name given to the altar, would impress upon the minds of the cowardly mob that he had brought out of Egypt --and who now had looked into an enemy's eyes for the first time--the elevating and bracing thought that they were God's soldiers, and that the warfare which they waged was not for themselves, nor for the conquest of the country for their own sake, nor for mere outward liberty, but that they were fighting that the will of God might prevail, and that He might be the King now of one land--a mere corner of the earth--and thereby might come to be King of all the earth. That rude altar said to Israel: Remember, when you go into the battle, that the battle is the Lord's; and that the standard under which you war is the God for whose cause you contend--none else and none less than Jehovah Himself. You are consecrated soldiers, set apart to fight for God.'
Such is the destination of all Christians. They have a battle to fight, of which they do not think loftily enough, unless they clearly and constantly recognize that they are fighting on God's side.
I need not dwell upon the particulars of this conflict, or run into details of the way in which it is to be waged. Only let us remember that the first field upon which we have to fight for God we carry about within ourselves; and that there will be no victories for us over other enemies until we have, first of all, subdued the foes that are within. And then let us remember that the absorbing importance of inward conflict absolves no Christian man from the duty of strenuously contending for all things that are lovely and of good report,' and from waging war against every form of sorrow and sin which his influence can touch. There is no surer way of securing victory in the warfare within and conquering self than to throw myself into the service of others, and lose myself in their sorrows and needs. There is no possibility of my taking my share in the merciful warfare against sin and sorrow, the tyrants that oppress my fellows, unless I conquer myself. These two fields of the Christian warfare are not two in the sense of being separable from one another, but they are two in the sense of being the inside and the outside of the same fabric. The warfare is one, though the fields are two.
Let us remember, on the other hand, that whilst it is our simple bounden duty, as Christian men and women, to reckon ourselves as anointed and called for the purpose of warring against sin and sorrow, wherever we can assail them, there is nothing more dangerous, and few things more common, than the hasty identification of fighting for some whim, or prejudice, or narrow view, or partial conception of our own, with contending for the establishment of the will of God. How many wicked things have been done in this world for God's glory I How many obstinate men, who were really only forcing their own opinions down people's throats because they were theirs, have fancied themselves to be pure-minded warriors for God! How easy it has been, in all generations, to make the sign of the Cross over what had none of the spirit of the Cross in it; and to say, The cause is God's, and therefore I war for it'; when the reality was, The cause is mine, and therefore I take it for granted that it is God's.'
Let us beware of the wolf in sheep's clothing,' the pretence of sanctity which is only selfishness with a mask on. And, above all, let us beware of the uncharitableness and narrowness of view, the vehemence of temper, the fighting for our own hands, the enforcing of our own notions and whims and peculiarities, which have often done duty as being true Christian service for the Master's sake. We are God's host, but we are not to suppose that every notion that we take into our heads, and for which we may contend, is part of the cause of God.
And then remember what sort of men the soldiers in such an army ought to be. Be ye clean that bear the vessels of the Lord.' These bearers may either be regarded as a solemn procession of priests carrying the sacrificial vessels; or, as is more probable from the context of the original, as the armourbearers of the great King. They must be pure who bear His weapons, for these are His righteous love, His loving purity. If our camp is the camp of the Lord, no violence should be there. What sanctity, what purity, what patience, what long-suffering, what self-denial, and what enthusiastic confidence of victory there should be in those who can say, We are the Lord's host, Jehovah is our Banner!' He always wins who sides with God. And he only worthily takes his place in the ranks of the sacramental host of the Most High who goes into the warfare knowing that, because He is God's soldier, he will come out of it, bringing his victorious shield with him, and ready for the laurels to be twined round his undinted helmet. That is the first of the thoughts, then, that are here.
