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.
Paul saith, "Godliness with contentment, is great gain." It is by faith that a Christian enjoys God, it is by love that he enjoys his neighbor, and by contentment that he enjoys himself.
