Now, all our Lord's miracles are parables, illustrating upon a lower platform spiritual facts; and that is especially true about the miracles of healing. So I wish to deal with the words before us as having a direct application to ourselves, and to draw from them two or three very old, threadbare, neglected lessons, which I pray God may lead some of us to recognise anew our need of healing, and Christ's infinite power to bestow it. There are three things that I want to say, and I name them here that you may know where I am going. First, we all need healing; second, Christ can heal us all; third, we are not all healed. I. We all need healing. The people in that crowd were not all diseased. Some of them He taught; some of them He cured; but that crowd where healthy men mingled with cripples is no type of the condition of humanity. Rather we are to find it in that Pool of Bethesda, with its five porches, wherein lay a multitude of impotent folk, tortured with varieties of sickness, and none of them sound. Blessed be God! we are in _Bethesda_, which means 'house of mercy,' and the fountain that can heal is perpetually springing up beside us all. There is a disease, dear brethren, which affects and infects all mankind, and it is of that that I wish to speak to you two or three plain, earnest words now. Sin is universal. What does the Bible mean by sin? Everything that goes against, or neglects God's law. And if you will recognise in all the acts of every life the reference, which really is there, to God and His will, you will not need anything more to establish the fact that 'all have sinned, and come short of the glory of God.' Whatever other differences there are between men, there is this fundamental similarity. Neglect--which is a breach--of the law of God pertains to all mankind. Everything that we do ought to have reference to Him. _Does_ everything that we do have such reference? If not, there is a quality of evil in it. For the very definition of sin is living to myself and neglecting Him. He is the centre, and if I might use a violent figure, every planet that wrenches itself away from gravitation towards, and revolution round, that centre, and prefers to whirl on its own axis, has broken the law of the celestial spheres, and brought discord into the heavenly harmony. All men stand condemned in this respect.
