Afterward Jesus found him in the temple, and said unto him,
Behold, you are made whole: sin no more, lest a worse thing come unto you.

Sin no more By these words our Saviour shews, that his infirmity was sent in punishment of his sins. When our souls are covered with the leprosy of sin, we are frequently insensible of our misfortune; whereas, as soon as the body is attacked with sickness, though ever so inconsiderable, we are not to be pacified till the physician has been consulted, and some remedy applied to remove, if possible, the complaint. (St. Chrysostom, hom. xxxvii. in Joan.)
Men are astonished that God, for so short a pleasure as is found in the perpetration of sin, should have decreed an everlasting punishment in the fire of hell; for they say, Shall I be punished for ever, for having indulged a sinful thought for a single moment? But their astonishment will cease, when they consider that punishments are not inflicted on sins in proportion to the length of time that was spent in their perpetration, but that they are proportioned to their malice. Now the malice of sin being infinite, aimed against the infinite majesty and infinite sanctity of God, the punishment, to be any ways commensurate, must be infinite. If, therefore, the sinner dies charged with the infinite debt of mortal sin unrepented of, as the time of mercy and repentance finishes with the present life, the sin must necessarily remain, God's hatred for sin must necessarily remain, and the punishment justly inflicted must necessarily continue. (Haydock)
These words are applicable to every penitent sinner, when he returns from the tribunal of confession, and show how careful he ought to be not to relapse into his former sins. "For he who after pardon sins again, is unworthy of mercy; who being cured, makes himself sick again, and who being cleansed, defiles himself again. "(Tom. ii. St. Chrysostom, de lapsu prim. hom.)
