Our Lord deals with this question of the concert of prayer in the eighteenth chapter of Matthew. He deals with the benefit and energy resulting from the aggregation of prayer forces. The prayer principle and the prayer promise will be best understood in the connection in which it was made by our Lord: “Moreover, if thy brother shall trespass against thee, go and tell him his fault between thee and him alone: if he shall hear thee, thou hast gained thy brother. But if he will not hear thee, then take with thee one or two more, that in the mouth of two or three witnesses, every word may be established. “And if he shall neglect to hear them, tell it unto the church; but if he neglect to hear the church, let him be unto thee as an heathen and a publican. “Verily I say unto you, Whatsoever ye shall bind on earth, shall be bound in heaven; and whatsoever ye shall loose on earth, shall be loosed in heaven. Again I say unto you, That if two of you shall agree on earth as touching any thing that they shall ask, it shall be done for them of my Father which is in heaven. For where two or three are gathered together in my name, there am I in the midst of them.” This represents the Church in prayer to enforce discipline in order that its members who have been overtaken by faults, may yield readily to the disciplinary process. In addition, it is the Church called together in a concert of prayer in order to repair the waste and friction ensuing upon the cutting off of a Church offender. This last direction as to a concert of prayer is that the whole matter may be referred to Almighty God for His approval and ratification. All this means that the main, the concluding and the all powerful agency in the Church is prayer, whether it be, as we have seen in Matthew, 9th chapter, to thrust out labourers into God’s earthly harvest fields, or to exclude from the Church a violator of unity, law and order, who will neither listen to his brethren nor repent and confess his fault. It means that Church discipline, now a lost art in the modern Church, must go hand in hand with prayer, and that the Church which has no disposition to separate wrong doers from the Church, and which has no excommunication spirit for incorrigible offenders against law and order, will have no communication with God. Church purity must precede the Church’s prayers. The unity of discipline in the Church precedes the unity of prayers by the Church. Let it be noted with emphasis that a Church which is careless of discipline will be careless in praying. A Church which tolerates evil doers in its communion, will cease to pray, will cease to pray with agreement, and will cease to be a Church gathered together in prayer in Christ’s name.
