Feebleness in prayer is the mark of disease. Impotence to walk is, in the Christian, as in the natural life, a terrible proof of some evil in the system that needs a physician. The lack of power to walk joyfully in the new and living way that leads to the Father and the throne of grace is specially grievous. Christ is the great Physician, who comes to every Bethesda where impotent folk are gathered, and speaks out his loving, searching question, Wilt thou be made whole? For all who are still clinging to their hope in the pool, or are looking for some man to put them in, who are hoping, in course of time, somehow to be helped by just continuing in the use of the ordinary means of grace, His question points to a better way. He offers them healing in a way of power they have never understood. And to all who are willing to confess, not only their own impotence, but their failure to find any man to help them, His question brings the sure and certain hope of a near deliverance. We have seen that our weakness in prayer is part of a life smitten with spiritual impotence. Let us listen to our Lord as He offers to restore our spiritual strength, to fit us for walking like healthy, strong men in all the ways of the Lord, and so be fit rightly to fill our place in the great work of intercession. As we see what the wholeness is He offers, how He gives it, and what He asks of us, we shall be prepared for giving a willing answer to His question. WHAT THE HEALTH THAT JESUS OFFERS. I might mention many marks of spiritual health. Our text leads us to take one,--walking. Jesus said to the sick man, Rise and walk, and with that restored him to his place among men in full health and vigour, able to take his part in all the work of life. It is a wonderfully suggestive picture of the restoration of spiritual health. To the healthy, walking is a pleasure; to the sick, a burden, if not an impossibility. How many Christians there are to whom, like the maimed and the halt and the lame and the impotent, movement and progress in God's way is indeed an effort and a weariness. Christ comes to say, and with the word He gives the power, Rise and walk.
