That is what Christ said in the context. The sentence which I have taken as my text was spoken at the close of the Parable of the Sower; and when His disciples came and asked Him why He spake in parables, His answer was in effect that the people to whom He spoke had not profited by what they had heard; hearing, they heard not,' and therefore He spoke in parables which veiled as well as revealed the truth. It was not given to them to know the mysteries of the Kingdom, because they had not given heed to what had been made known to them. The great law was taking effect which gives to him that has and takes from him that has not; and that law applied not only to the form of Christ's teaching, but also to the faculty of receiving it. That diminished capacity is sometimes represented as men's own act, and sometimes as the divinely inflicted penalty of not hearing, but in either case the same fact is in view--namely, the loss of susceptibility by neglect, the dying-out of faculties by disuse.
Just as in the bodily life capacities untrained and unexercised become faint and disappear; just as the Indian fakir, who holds his arm up above his head for years, never using the muscles, has the muscles atrophied, and at last cannot bring his arm down to his side;--so the people who neglect to use the ears that God has given them by degrees will lose the capacity of hearing at all. Which, being put into plain English, just comes to this: that if we do not. listen to Jesus Christ when He calls to us in His love, we shall gradually have the capacity of hearing diminished until, I do not know if it ever reaches that point here--until its ultimate extinction.
Dear friends, this word of the love and pity and pardon and purifying power of God manifest in Jesus Christ for us all, which I am trying to preach to you now, is not without an effect even on the men by whom it is most superficially and perfunctorily heard. It either softens or hardens. As the old mystics used to say, the same heat that melts wax hardens clay into brick. The same light that brings blessing to one eye brings pain to another. You have heard, and hearing you have not heard; and you will cease to be able to hear at all; and then the thunders may rattle over your heads, and be inaudible to you; and that Voice which is as loud as the sound of many waters, and sweet as harpers harping on their harps, and which says to each of us,' Come to Me, and I will be thy peace and thy rest and thy strength,' will no more be audible in your atrophied ears. Dear friends! I do not know, as I have said, whether that ultimate tragic result is ever wholly reached in this world. I am sure that it is not reached with some of you as yet. And I beseech you to obey that voice which says, This is My beloved Son; hear Him,' and to let there not be only outward hearing, but to let there be inward acceptance, attention, apprehension, and obedience. And then we shall be able to say, Blessed are our ears, for they hear; blessed are our eyes, for they see.' Many prophets and righteous men desired to hear the things that ye hear, and heard them not, take care that, since you are thus advanced in the outward possession of the perfect word of God, there be also the yielding to, and reception of it.
