When Jesus saw him lie, and knew that he had been now a long time in that case, he saith unto him, Wilt thou be made whole?

People's New Testament

5:6 Wilt thou be made whole? Jesus observed him and asked the question to arouse his attention.

Jamieson-Fausset-Brown Bible Commentary

6. saw him lie, and knew, &c.-As He doubtless visited the spot just to perform this cure, so He knows where to find His patient, and the whole previous history of his case (Joh 2:25).

Wilt thou be made whole?-Could anyone doubt that a sick man would like to be made whole, or that the patients came thither, and this man had returned again and again, just in hope of a cure? But our Lord asked the question. (1) To fasten attention upon Himself; (2) By making him detail his case to deepen in him the feeling of entire helplessness; (3) By so singular a question to beget in his desponding heart the hope of a cure. (Compare Mr 10:51).

Matthew Henry's Concise Commentary

5:1-9 We are all by nature impotent folk in spiritual things, blind, halt, and withered; but full provision is made for our cure, if we attend to it. An angel went down, and troubled the water; and what disease soever it was, this water cured it, but only he that first stepped in had benefit. This teaches us to be careful, that we let not a season slip which may never return. The man had lost the use of his limbs thirty-eight years. Shall we, who perhaps for many years have scarcely known what it has been to be a day sick, complain of one wearisome night, when many others, better than we, have scarcely known what it has been to be a day well? Christ singled this one out from the rest. Those long in affliction, may comfort themselves that God keeps account how long. Observe, this man speaks of the unkindness of those about him, without any peevish reflections. As we should be thankful, so we should be patient. Our Lord Jesus cures him, though he neither asked nor thought of it. Arise, and walk. God's command, Turn and live; Make ye a new heart; no more supposes power in us without the grace of God, his distinguishing grace, than this command supposed such power in the impotent man: it was by the power of Christ, and he must have all the glory. What a joyful surprise to the poor cripple, to find himself of a sudden so easy, so strong, so able to help himself! The proof of spiritual cure, is our rising and walking. Has Christ healed our spiritual diseases, let us go wherever he sends us, and take up whatever he lays upon us; and walk before him.
