2. Islam is broken up into some two hundred sects; Christianity into as many, or more. The family feuds have, in each case, been fiercely maintained. But, at the call—“_Fight for the religion of God_,” Islam rallies as one man, a solid front is offered to the enemies of the Faith. Just at this point, once again, Christianity has failed. The family feud is carried into the enemy’s country, and weakens the aggressive warfare, as only those who have taken part in that warfare can tell. 3. The solidarity of societies is a rarely realized but very solemn fact. The Church of Christ cannot divide herself into portions, and fling responsibilities from division to division, from age to age. Whether consciously or not, when one member suffers all suffer, when one member sins sin has come upon all; and history teaches no lesson more plainly than that the harvest of the deeds of one generation is reaped by another. Thus, the most solemn lesson provided by the story of Islam is contained in the very existence of Islam. A disloyal Church presented a false Faith to one of the most earnest Seekers after God who has ever gone forth upon the great Quest; and the Church has spent much wrath upon the “false Prophet” who has ever since been her greatest opponent. But she has never fairly faced her sin, nor acknowledged that the Islam of to-day is to all intents the harvest of the seed of false doctrine she sowed thirteen centuries ago. To discuss the truth or the falsehood of Muhammad’s claim will be the task of Islam when she is brought face to face with the true Christ; it is beside the mark for the Church of Christ. To her falls the far more awful duty of wiping out as best she may, and at whatever cost, the darkest blot which has marred her long history. Can it be that her Lord cannot largely own her aggressive work done in His Name, until the wrong has been righted? III THE COMING BATTLE “_Fight for the religion of God, and know that God is He Who heareth and knoweth._” Muhammad. “_Go ye therefore, and make disciples of all the nations ... and lo, I am with you alway, even unto the end of the world._” Jesus Christ. THE COMING BATTLE. Islam and Christianity are not sister religions, as some would have us believe. The very existence of Islam is a challenge to Christianity; and since Muhammad sent out his missionary armies, the two Faiths have been constant rivals and enemies. All apologists of any weight on both sides acknowledge the mutual exclusion of Christ and Muhammad. Nothing is gained on either side by denial of this position.
