john 5:7 The impotent man answered him, Sir, I have no man, when the water is troubled, to put me into the pool: but while I am coming, another steppeth down before me. - Free Bible Online

      7. Sir, I have no man, &c.--Instead of saying he wished to be cured, he just tells with piteous simplicity how fruitless had been all his efforts to obtain it, and how helpless and all but hopeless he was. Yet not quite. For here he is at the pool, waiting on. It seemed of no use; nay, only tantalizing,
      while I am coming, another steppeth down before me--the fruit was snatched from his lips. Yet he will not go away. He may get nothing by staying, he may drop into his grave ere he get into the pool; but by going from the appointed, divine way of healing, he can get nothing. Wait therefore he will, wait he does, and when Christ comes to heal him, lo! he is waiting his turn. What an attitude for a sinner at Mercy's gate! The man's hopes seemed low enough ere Christ came to him. He might have said, just before "Jesus passed by that way," "This is no use; I shall never get in; let me die at home." Then all had been lost. But he held on, and his perseverance was rewarded with a glorious cure. Probably some rays of hope darted into his heart as he told his tale before those Eyes whose glance measured his whole case. But the word of command consummates his preparation to receive the cure, and instantaneously works it.
