We may also fitly remember that Satan has his miracles, which, though they are deceitful tricks rather than true powers, are such a sort as to mislea… - John Calvin

Let the Nuns therefore tarry still in their convents and cloisters, and in their brothel houses of Satan: yea I put the case they were not whores as they are, yea and worse than that, vile and shameful Sodomites, committing such heinous and abominable acts, that it is horrible to think of, I put the case I say, there were none of all these villainies, yet all the chastity they pretend is nothing before God, in comparison of that that he hath appointed, that is to say, that albeit it seem but a vile thing, and a matter of none account, for a woman to take pains about housewifery, to make clean her children when they be arrayed, to kill fleas, and other such like, although this be a thing despised, yea and such, that many will not vouchsafe to look upon it, yet are they sacrifices which GOD accepteth & receiveth, as if they were things of great price and honourable.

But a faithful believer will in all circumstances mediate on the mercy and fatherly goodness of God.

Without knowledge of self there is no knowledge of God. Our wisdom, in so far as it ought to be deemed true and solid Wisdom, consists almost entirely of two parts: the knowledge of God and of ourselves. But as these are connected together by many ties, it is not easy to determine which of the two precedes and gives birth to the other.
