So if Christian individuals and Christian communities are impotent, or all but impotent, there is no difficulty in understanding why. They have cut the connection, they have shut the tap. They lack faith; and so their power is weakness. 'Why could we not cast him out?' said they, perplexed when they had no need to be. 'Why could you not cast him out? Because you do not believe that I, working in you, can cast him out. That is why; and the only why.' Let us learn that the secret of Christians' weakness is the weakness of their Christian faith.
And the other condition is prayer. 'Whatsoever ye shall ask in My name I will do it,' and He repeats it, for confirmation and for greater emphasis. 'If ye shall ask anything in My name,' or, as perhaps that clause ought to be read with some versions, 'If ye shall ask Me anything in My name I will do it.'
Three points may be named here. Our power depends upon our prayer. God's and Christ's fullness and willingness to communicate do not depend upon our prayer. But our capacity to receive of that fullness, and so the possibility of its communication to us, do depend upon our prayer. 'We have not because we ask not.'
The power of our prayer depends upon our conscious oneness with the revealed Christ. 'If ye shall ask in My name,' says He. And people think they have fulfilled the condition when, in a mechanical and external manner, they say, as a formula at the end of petitions that have been all stuffed full of self-will and selfishness, 'for Christ's sake. Amen!' and then they wonder they do not get them answered! Is that asking in Christ's name?
Christ's name is the revelation of Christ's character, and to do a thing in the name of another person is to do it as His representative, and as realising that in some deep and real sense—for the present purpose at all events—we are one with Him. And it is when we know ourselves to be united to Christ and one with Him, and representative in a true fashion of Himself, as well as when, in humble reliance on His work for us and His loving heart, we draw near, that our prayer has power, as the old divines used to say, 'to move the Hand that moves the world,' and to bring down a rush of blessing upon our heads. Prayer in the name of Christ is hard to offer. It needs much discipline and watchfulness; it excludes all self-will and selfishness. And if, as my text tells us, the end of the Son's working is the glory of the Father, that same end, and not our own ease or comfort, must be the end and object of all prayer which is offered in His name. When we so pray we get an answer. And the reason why such multitudes of prayers never travel higher than the roof, and bring no blessings to him who prays, is because they are not prayers in Christ's name.
Prayer in His name will pass into prayer to Him. As He not obscurely teaches us here (if we adopt the reading to which I have already referred), He has an ear to hear such requests, and He wields divine power to answer. Surely it was not blasphemy nor any diversion of the worship due to God alone, when the dying martyr outside the city wall cried and said, 'Lord Jesus! receive my spirit.' Nor is it any departure from the solemnest obligations laid upon us by the unity of the divine nature, nor are we bringing idolatrous petitions to another than the Father, when we draw near to Christ and ask Him to give us that which He gives as the Father's gift, and to work on us that which the Father that dwelleth in Him works through Him for us.
