The divine life in three treatises

But let humane Nature be cured of its blindness, carnality and corruption, and then it will need no external testimony to convince it, that no employment is so natural and suitable to man, as to Walk with God, in Love and Confidence, and reverent Worship, and cheerful Obedience to his Will. A worldly fleshly sensual life, will then appear to be below the rational nature of a man, as it is below us to go to grass with horses, or to live as mere companions of brutes. It will then appear to be as natural for us to Love and Live to our Creator and Redeemer, and to Walk with God, as for a Child to love his Parents, and to live with them and serve them. When I say that this is Natural, I mean not that it is Necessary by Natural Necessity, or that Grace doth operate per modum naturae, as the irrational motion is so called. There is a Brutish or Inanimate Nature, and there is a Rational Voluntary Nature: Grace worketh not according to the way of Inanimate or Brutish Nature, but according to the way of Rational Nature, in free Agents. I may well say that whatever is Rational, is Natural to a Rational Creature as such, so far as he discerneth it. Yea and Habits, though they effect not necessarily, but freely in a Rational nature, yet they Incline Necessarily, & per modum naturae. They contain in their being a Natural aptitude and propensity to action.
