in her devotion, adoration and worship, as she ought, nor so well observant of God as God is observing her: Nevertheless, there is not any of her parts or creatures, that God is not acknowledged by, though not so perfectly as he ought, which is caused by the irregularities of nature, as I said before. And so God of his mercy have mercy upon all Creatures; To whose protection I commend your Ladiship, and rest, Madam, _Your faithful Friend_ _and Servant._ [1] _Antidote, Book_ I. _c._ 10. _a._ 5. II. _MADAM,_ Since I spake in my last of the adoration and worship of God, you would faine know, whether we can have an Idea of God? I answer, That naturally we may, and really have a knowledge of the existence of God, as I proved in my former letter, to wit, that there is a God, and, that he is the _Author_ of all things, who rules and governs all things, and is also the God of Nature: but I dare not think, that naturally we can have an Idea of the essence of God, so as to know what God is in his very nature and essence; for how can there be a finite Idea of an Infinite God? You may say, As well as of Infinite space. I answer, Space is relative, or has respect to body, but there is not any thing that can be compared to God; for the Idea of Infinite nature is material, as being a material creature of Infinite material Nature. You will say, How can a finite part have an Idea of infinite nature? I answer, Very well, by reason the Idea is part of Infinite Nature, and so of the same kind, as material; but God being an Eternal, Infinite, Immaterial, Individable Being, no natural creature can have an Idea of him. You will say, That the Idea of God in the mind is immaterial; I answer, I cannot conceive, that there can be any immaterial Idea in nature; but be it granted, yet that Immaterial is not a part of God, for God is individable, and hath no parts; wherefore the Mind cannot have an Idea of God, as it hath of Infinite nature, being a part of nature; for the Idea of God cannot be of the essence of God, as the Idea of nature is a corporeal part of nature: and though nature may be known in some parts, yet God being Incomprehensible, his Essence can by no wayes or means be naturally known; and this is constantly believed, by Madam, _Your faithful Friend,_ _and Servant._ III. _MADAM,_
