And so, brethren, here is the reason--I do not say the only reason, but the main one, and that which most affects us--for the slow progress, and even apparent failure, of Christianity. It has fallen into the hands of a Church that does not half believe its own Gospel. By reason of formality and ceremonial and sacerdotalism and a lazy kind of expectation that, somehow or other, the benefits of Christ's love can come to men apart from their own personal faith in Him, the Church has largely ceased to anticipate that great things can be done by its utterance of the Name. And if you have, I do not say ministers, or teachers, or official proclaimers, or Sunday-school teachers, or the like, but I say if you have a _Church_, that is honeycombed with doubt, and from which the strength and flood-tide of faith have in many cases ebbed away, why, it may go on uttering its formal proclamations of the Name till the Day of Judgment, and all that will come of it will be--'The man in whom the devils were, leaped upon them, and overcame them, and said'--as he had a good right to say--'Jesus I know, and Paul I know, but who are ye?' You cannot kindle a fire with snowballs. If the town crier goes into a quiet corner of the marketplace and rings his bell apologetically, and gives out his message in a whisper, it is small wonder if nobody listens. And that is the way in which too many so-called Christian teachers and communities hold forth the Name, as if begging pardon of the world for being so narrow and old-fashioned as to believe in it still.
And no less necessary is faith on the other side. The recipient must exercise trust. This lame man, no doubt, like the other that Paul looked at in a similar case, had faith to be healed. That was the length of his tether. He believed that he was going to have his legs made strong, and they were made strong accordingly. If he had believed more, he would have got more. Let us hope that he did get more, because he believed more, at a later day. But in the meantime the Apostles' faith was not enough to cure him; and it is not enough for you that Jesus Christ should be standing with all His power at your elbow, and that, earnestly and enthusiastically, some of Christ's messengers may press upon you the acceptance of Him as a Saviour. He is of no good in the world to you, and never will be, unless you have the personal faith that knits you to Him.
It cannot be otherwise. Depend upon it, if Jesus Christ could save every one without terms and conditions at all, He would be only too glad to do it. But it cannot be done. The nature of His work, and the sort of blessings that He brings by His work, are such as that it is an impossibility that any man should receive them unless he has that trust which, beginning with the acceptance by the understanding of Christ as Saviour, passes on to the assent of the will, and the outgoing of the heart, and the yielding of the whole nature to Him. How can a truth do any good to any one who does not believe in it? How is it possible that, if you do not take a medicine, it will work? How can you expect to see, unless you open your eyes? How do you propose to have your blood purified, if you do not fill your lungs with air? Is it of any use to have gas-fittings in your house, if they are not connected with the main? Will a water tap run in your sculleries, if there is no pipe that joins it with the source of supply? My dear friend, these rough illustrations are only approximations to the absolute impossibility that Christ can help, heal, or save any man without the man's personal faith. 'Whosoever believeth' is no arbitrary limitation, but is inseparable from the very nature of the salvation given.
