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. III. And now, lastly, note the effects of the power of the Name.
