Mortify therefore your members which are upon the earth; fornication, uncleanness, inordinate affection, evil concupiscence, and covetousness, which is idolatry:
Ver. 5. Mortify therefore] Sin hath a strong heart, and will not be done to death but with much ado. Peccata saepe raduntur, sed non eradicantur. Sins often are itchy but are not rooted out. Something is done about sins, little against them; as artificial magicians seem to wound themselves, but do not; or as players seem to thrust themselves through their bodies, but the sword passeth only through their clothes. Some part with sin, as Jacob did with Benjamin, because otherwise he should starve; or as Phaltiel did with Michal, lest he should lose his head; but to cast it away because it is offensivum Dei, et aversivum a Deo, an offence against God, and a breach of his law, this is mortification; this is more than to have seraphical knowledge and cherubinical affections in any duty. This (saith a Father) is the hardest text in all the Bible, and the hardest task in all Christianity that we can go about; but hard or not hard, it must be done, or we are undone, and check must be given to our corruptions, though full mate we cannot give.
Covetousness, which is idolatry] For it robs God of his flower, his trust, and draws a man away from all the commandments,Psalms 119:36. See Trapp on " Eph 5:5 "
