This is true godliness: it is not a bare living up to the natural principles of morality nor a simple knowledge of the letter of the Word or a historical, notional, or dogmatical knowledge of the sacred gospel and the precepts thereof; but in a faithful living up to the supernatural principles of grace and the gospel, discharging our duties with as much readiness and faithfulness toward God as toward man, so that our conscience may be kept void of offense toward both (Acts 24:16). It consists in forsaking of every sin and not only to leave it but to loathe it as the greatest evil and to cleave to God in sincerity of heart, valuing Him above all who is the chiefest good and, from a principle of divine love, willingly subjecting to all His laws and appointments.
We conceive it is so excellent a grace, this grace of contentment, that it is indeed a compound of these five graces: faith, humility, patience, hope, and mortification. In a manner, contentment is the result of all these exercising themselves in one; and except these be in a most vigorous exercise, absolute contentment is not easily to be attained.
We may say, if a Christian made the world but his servant, a little would content him; but if once he make the world his master and lord of his affections, then his desires will be infinite and cannot at all be satisfied.
the gleanings of a Christian are better than the vintage of a reprobate. "A little that a righteous man hath is better than the riches of many wicked."Works, 398
