Stephen Charnock: The Moral Nature Does Not Necessarily Prepare for Regeneration

Moral nature seems to be a preparation for grace; if it be so, it is not a cause howsoever of grace, for then the most moral person would be soonest gracious, and more eminently gracious after his renewal, and none of the rubbish and dregs of the world would ever be made fit for the heavenly building. There seems to be a fitness in morality for the receiving special grace, because the violence and tumultuousness of sin is in some measure appeased, the flame and sparks of it allayed, and the body of death lies more quiet in them, and the principles cherished by them bear some testimony to the holiness of the precepts. But though it seems to set men at a greater nearness to the kingdom of God, yet with all its own strength it cannot bring the kingdom of God into the heart, unless the Spirit opens the lock. Yea, sometimes it sets a man further from the kingdom of God, as being a great enemy to the righteousness of the gospel, both imputed and inherent, which is the crown of the gospel: to imputed, as standing upon a righteousness of their own, end conceiving no need of any other; to inherent, as acting their seeming holiness neither upon gospel principles, nor for gospel ends, but in self-reflections and self-applauses. What may seem preparations to us in matters of moral life, may in the root be much distant and vastly asunder from grace; as a divine of our own illustrates it, two mountains whose tops seem near together may in the bottom be many miles asunder.  [From:  A Discourse of the Efficient of Regeneration].
