“To some, we must lay open our hearts freely and exactly; to others more reservedly; to others we should be altogether locked up, concealing from them what we see no disposition in them to make a good use of.”
*22. Zeal indeed should be always attended with prudence, to consider things well, and execute them in the best manner; to prevent mischiefs, or redress them with as much of sweetness, and as little acrimony as possible: and in desperate cases, or where the cure would prove worse than the disease, to suffer and pass them over; some souls having defects, as it were, incorrigible, which God permits to perfect them by humility; and others likewise, that have an intercourse with them, by patience and charity.
*23. One great point of prudence requisite in a zealous man, is, neither to hurt his body by too much labour, nor his mind with too much business. As to the latter of these, M. _de Renty_ took especial care, so to manage all his works of charity, that his piety might not be hindered but advanced thereby, indispensably performing all his exercises of devotion; and while he conversed most with his neighbour, reserving a considerable part, both of the day and night, for conversing with God. As to the other, he thus expressed himself to a clergyman, who had impaired his health by extreme labour:
“Give me leave, Sir, to tell you plainly, that you should not impose too much upon yourself, lest for want of moderation, you render yourself altogether unserviceable. The enemy usually takes no small advantage of such free and well-disposed natures; you are not your own, but a debtor to all men. Preserve yourself therefore, not by indulging your body, but by laying upon it no more than it is able to bear.”
24. Being at _Citry_, in the latter end of the year 1642, he had a strong impression upon his spirit, that at his return to _Paris_, he should find a new employment about the poor, and be much taken up therein. Accordingly, two days after his return thither, some persons came to advise with him, about a course of relieving all such poor in the city, as were ashamed to beg. He undertook to visit a fourth part of them, and to assist them according to their necessities. An employment sufficient to take up the whole time of one man, which yet he performed, notwithstanding the multitude of his other occupations; so that we must say, without a special assistance, he could not have done and suffered what he did; but God, who hath limited our strength of body, can increase it when and how he pleaseth.
25. Sometimes he received before-hand only a present impulse of something to be done, without any particular discovery. As when he was much pressed in spirit to go to _Pontois_, without understanding any reason for it; yet, believing it to be the call of God, he immediately undertook the journey; where unexpectedly he met with a nobleman of great quality, who was come from a province far distant, on purpose to be instructed by M. _de Renty_, how to serve God, which he had, till then, little known, and less practised.
26. But though this great servant of God had an excellent faculty of assisting all, yet was he more eminently assistant to some particular persons, for the healing their souls, and leading them on apace in the narrow way of perfection. I shall mention one only, the Countess of _Chatres_, who being deep in the affections of the world, as are most young ladies of her quality, it pleased God to inspire her with a desire to ask advice of M. _de Renty_; this he gave her with so happy success, that he himself was astonished at it. In less than a year, she was so perfectly disengaged from all those little conveniences and accommodations, which our ladies perswade themselves are absolutely necessary, that one offering her something of this kind, which she was formerly fond of, she answered, “I thank God, I have quitted this, and many more things, for the love of God, and yet find no want at all.”
27. God gave him light to discern her proper way, how to renounce herself, and advance in the paths of solid virtue, and to support her in great inward afflictions. And she, on her part, resigned up herself to his guidance, and forced herself to put his advice in execution: a thing very requisite in those who would make use of the conduct of others to good purpose.
