and godliness?
not as the scoffers and profane sinners, who put away this evil day far from them, but as men, who have their loins girt, and their lights burning, waiting for their Lord's coming; being continually in the exercise of grace, and in the discharge of their religious duties, watching, praying, hearing, reading; living soberly, righteously, and godly; guarding against intemperance and worldly mindedness, and every worldly and hurtful lust.
