John 5:14

Afterwards Jesus, &c. The Arabic is, Now thou art healed, return not to sin, less a worse evil be done thee.

In the Temple. From this it appears that this man who was healed by Christ, as soon as he had carried his bed to his house, went to the Temple to give God thanks for His great benefit of healing. As Chrysostom says, "Assuredly a great mark of piety and reverence. He did not go to the marketplace, or the porch; he did not indulge in pleasure, or ease; he was occupied in the Temple."

Sin no more. From hence it is plain that God often sends diseases upon sick persons on account of their sins; and that this man had been afflicted because of his sins. Thus this paralytic, who had been sick for thirty-eight years, from a time before Christ was born, had committed some crime, which God wished him to suffer for, and expiate, by this protracted disease. Christ therefore tacitly admonishes the man's conscience that he should be mindful of his sin, and be contrite, and avoid it for the time to come. At the same time He intimates that He, being a Prophet, knew this by Divine revelation. Wherefore when sickness is sent by God upon any one, let him examine his conscience, and blot out by repentance and confession the sin for which God has sent the sickness, and let him pray to God to pardon his sin, and take away the disease.

I said, often sends, for God sometimes sends diseases upon holy men that he may prove, increase, and crown their patience, as He did in the case of Job, whose whole dispute with his friends turned upon this point; his friends urging that his sins had given occasion to his being so grievously afflicted, whilst he, on the contrary, contended that he was free from sins, and had not deserved those afflictions. And God in the last chapter adjudges the dispute in his favour, and condemns his friends. The same thing will appear in the case of the man who was born blind (chap. ix.), of whom Christ spake thus, "Neither did this man sin, nor his parents, that he was born blind."

Moreover, as Christ healed this sick man's body at the pool, so did He both by His inward inspiration, and by his external admonition, heal his soul in the Temple. He brought back to his memory the sins of his youth, by reason of which he had deserved so long a sickness, and he moved his heart to contrition for them, and to ask pardon from God, that so he might be justified. Indeed, Christ healed his body for this very reason that He might heal his soul.

Lest a worse thing, &c. "For," as Theophylact says, "he who is not made better by a former punishment is kept for greater torments, as being insensate, and a despiser." "And this happens," says Euthymius, "either in this life, or in the life to come, or in both." "A relapse is worse than the original disease." So a relapse into a fault is worse than the fault on account of the greater ingratitude, boldness, impudence.
