Own your General; submit to His authority; pick the weapons that He can bless; trust absolutely in His help. We _may_ have, we _shall_ have, in all enterprises for God and man that are worth doing, 'need of patience,' just as the army of Israel had to parade for six weary days round Jericho blowing their useless trumpets, whilst the impregnable walls stood firm, and the defenders flouted and jeered their aimless procession. But the seventh day will come, and at the trumpet blast down will go the loftiest ramparts of the cities that are 'walled up to heaven' with a rush and a crash, and through the dust and over the ruined rubbish Christ's soldiers will march and take possession. So trust in your Leader, and be sure of the victory, and have patience and keep on at your work. Do not make Joshua's mistake. 'Art Thou for us?'--'Nay! Thou art for _me._' That is a very different thing. We have the right to be sure that God is on our side, when we have made sure that we are on God's. So take care of self-will and self-regard, and human passions, and all the other parasitical insects that creep round philanthropic religious work, lest they spoil your service. There is a great deal that calls itself after Jehu's fashion, 'My zeal for the Lord,' which is nothing better than zeal for my own notions and their preponderance. Therefore we must strip ourselves of all that, and not fancy that the cause is ours, and then graciously admit Christ to help us, but recognise that it is _His_, and lowly submit ourselves to His direction, and what we do, do, and when we fight, fight, in His name and for His sake. III. Here is the Ally in all our warfare with ourselves. That is the worst fight. Far worse than all these Hittites and Hivites, and the other tribes with their barbarous names, far worse than all external foes, are the foes that each man carries about in his own heart. In that slow hand-to-hand and foot-to-foot struggle I do not believe that there is any conquering power available for a man that can for a moment be compared with the power that comes through submission to Christ's command and acceptance of Christ's help. He has fought every foot of the ground before us. We have to 'run the race'--to take another metaphor--'that is set before us, looking unto Jesus,' the great Leader, and in His own self the Perfecter of the faith which conquers. In Him, His example, the actual communication of His divine Spirit, and in the motives for brave and persistent conflict which flow from His Cross and Passion, we shall find that which alone will make us the victors in this internecine warfare. There can be no better directory given to any man than to tread in Christ's footsteps, and learn how to fight, from Him who in the wilderness repelled the triple assault with the single 'It is written'; thus recognising the word and will of God as the only directory and defence.
