Matthew 18:9

And if thine eye offend thee, pluck it out, and cast it from thee: it is better for thee to enter into life with one eye, rather than having two eyes to be cast into hell fire.

Ver. 9. Pluck it out] This is the circumcision of the heart, the mortification of earthly members, which is no less hard to be done than for a man with one hand to cut off the other, or to pull out his own eyes, and then rake in the holes where they grew. And yet, hard or not hard, it must be done; for otherwise we are utterly undone for ever. Hypocrites, as artificial magicians, seem to wound themselves, but do not: as stage players, they seem to thrust themselves through their bodies, whereas the sword passeth only through their clothes. But the truly religious lets out the life blood of his beloved lusts, lays them all dead at his feet, and burns their bones to lime, as the king of Moab did the king of Edom,Amos 2:1. As Joshua put down all the Canaanites, so doth grace all corruptions. As Asa deposed his own mother, so doth this, the mother of sin. It destroys them not by halves, as Saul, but hews them in pieces before the Lord, as Samuel.
