633. The case is this: With no man is there any understanding of truth and will of good, not even with those who were of the Most Ancient Church. But when men become celestial it appears as if they had a will of good and understanding of truth, and yet this is of the Lord alone, as they also know, acknowledge, and perceive. So is it with the angels also. So true is this that whoever does not know, acknowledge, and perceive that it is so, has no understanding of truth or will of good whatever. With every man, and with every angel, even the most celestial, that which is his own is nothing but falsity and evil; for it is known that the heavens are not clean before the Lord [Job 15:15], and that all good and all truth are of the Lord alone. But so far as a man or an angel is capable of being perfected, so far of the Lord's Divine mercy he is perfected, and receives as it were an understanding of truth and a will of good; but his having these is only an appearance. Every man can be perfected-and consequently receive this gift of the Lord's mercy-in accordance with the actual doings of his life, and in a manner suited to the hereditary evil implanted by his parents.
