Only remember this; look well to the ground on which you stand, keep a watchful eye upon every working of nature, and take care that nothing human, earthly, private, or selfish, mix with this heavenly fire: that is, see that your mind be free, universal, impartial, without regard to here or there, this or that, but loving all goodness, practicing every virtue, for itself, on its own account, because it is so much of God; neither coveting light, nor longing to communicate it to others, but merely and solely for this reason, that the will of God may be done, and the goodness of God brought to life both in you and them. For there is no goodness but God's; and his goodness is not alive, or fruitful in you, but so far, and in such degree, as the good that you mean, and do, is done in and by that Spirit, by which God himself is good. For as there is but one that is good, so there is, and can be but one goodness. And therefore it is, that we are called not to an human, worldly, prudential, partial goodness, suitable to our selfish reason, and natural tempers, but to be perfect, as our Father in heaven is perfect. And the full reason is expressed in the words; for if our Father is in heaven, we must be there too in spirit and life, or we are not his children; if heaven is that for which we are made, and that which we have lost, it is not any human goodness, but a heavenly birth and Spirit of God's own goodness, working in us, as it does in God, that can make us the heavenly children of our Father in heaven. You must love the light of God, as God loves it; you must desire that others may enjoy it, as God desires it. Now God is a free, universal, impartial love, loving and doing every kind of good, for its own sake, because that is the highest and most perfect working of life; and because everything else but goodness, for its own sake, is imperfect, and a degree of evil, misery, and death. And no creature can come out of its imperfection, misery, and death, but by the pure, free, unmixed goodness of God, being born in it. Though you had outwardly all virtues, and seemed doing all that the saints of God have done, yet unless the same Spirit, by which God himself is good, brought forth your goodness, all would be only an earthly labor, that could have no communication with heaven.
