"The proper course, therefore, is, in the first instance, to ascertain and examine the doctrine; ... then after it has been proved, but not till then, it may receive confirmation from miracles. But the mark of sound doctrine given by our Saviour himself is its tendency to promote the glory not of men, but of God (John 7:18; 8:50). Our Saviour having declared this to be test of doctrine, we are in error if we regard as miraculous, works which are used for any other purpose than to magnify the name of God."
