5:27-32 Victory over the desires of the heart, must be attended with painful exertions. But it must be done. Every thing is bestowed to save us from our sins, not in them. All our senses and powers must be kept from those things which lead to transgression. Those who lead others into temptation to sin, by dress or in other ways, or leave them in it, or expose them to it, make themselves guilty of their sin, and will be accountable for it. If painful operations are submitted to, that our lives may be saved, what ought our minds to shrink from, when the salvation of our souls is concerned? There is tender mercy under all the Divine requirements, and the grace and consolations of the Spirit will enable us to attend to them.

28. But I say unto you, That whosoever looketh on a woman to lust after her—with the intent to do so, as the same expression is used in Mt 6:1; or, with the full consent of his will, to feed thereby his unholy desires.

hath committed adultery with her already in his heart—We are not to suppose, from the word here used—"adultery"—that our Lord means to restrict the breach of this commandment to married persons, or to criminal intercourse with such. The expressions, "whosoever looketh," and "looketh upon a woman," seem clearly to extend the range of this commandment to all forms of impurity, and the counsels which follow—as they most certainly were intended for all, whether married or unmarried—seem to confirm this. As in dealing with the sixth commandment our Lord first expounds it, and then in the four following verses applies His exposition (Mt 5:21-25), so here He first expounds the seventh commandment, and then in the four following verses applies His exposition (Mt 5:28-32).
