Ver. 29,30. The sum of these two verses is, that the salvation of our immortal souls is to be preferred before all things, be they never so dear and precious to us; and that if men’s ordinary discretion teacheth them for the preservation of their bodies to cut off a particular member, which would necessarily endanger the whole body, it much more teacheth them to part with any thing which will prejudice the salvation of their souls. Not that any person is by this text obliged to cut off any bodily member, (as some have done), because there can be no such necessity; but only to mortify their members, Col_3:5, the deeds of the body, Rom_8:13, their inward lusts, which being mortified there will be no need of mutilating ourselves; for the members of the body are but commanded and animated to their motions from the inward lusts of the heart: but if there could happen such a case, as that a man must voluntarily part with the most useful member of his body, or sin against God to the damnation of his soul, he ought rather to choose the former than the latter. How much more then ought Christians to mortify their inward lusts and unlawful desires, which can be of no profit nor advantage to them; but will certainly make them to offend God, and so run them upon the danger of hell fire!
