Think of soldiers in an army fighting in their little sector. They are being hard-pressed and things are going against them. If they think that it is just their own private fight they will soon be defeated. But when they remember that they are only a part of a great and mighty army, and that at the back of it all, and directing it, is the Captain, their Leader, immediately the situation is entirely transformed. In other words, we have got to realize as we fight this fight of faith and wrestle with these principalities and powers and face the assaults of the world and the flesh and the devil, that God is involved in it with us. We would never have been in it but for that. The ultimate battle is the battle between God and the devil, between heaven and hell, between light and darkness. That in turn should make us realize a further truth, that this campaign cannot fail, because God’s honour is involved in it. Lift up your minds and your hearts in the thick of the battle and call this to mind. You see the might and the power of the enemy and you are conscious of your own weakness. But say to yourselves, ‘This is God’s battle, we are given the privilege of being in it and of fighting as individual soldiers, but God’s honour is involved in it all. He cannot allow this to fail because His character, His glory, and His honour are involved at every point.’ ‘Be strong in the Lord;’ remember that He is there, and that it is His battle. This cannot be emphasized too much.
