Here are a few morsels I found especially helpful or thought-provoking.
"Accustom yourself, then, by degrees thus to worship Him, to beg His grace, to offer Him your heart from time to time in the midst of your business, even every moment, if you can. Do not always scrupulously confine yourself to certain rules, or particular forms of devotion, but act with a general confidence in God, with love and humility." (Seventh Letter)
"[He] had no scruples; for, said he, when I fail in my duty, I readily acknowledge it, saying, I am used to do so; I shall never do otherwise if I am left to myself. If I fail not, then I give God thanks, acknowledging that the strength comes from Him." (Second Conversation)
"[We] might accustom ourselves to a continual conversation with Him [God], with freedom and in simplicity. [We] need only to recognize God intimately present with us, to address ourselves to Him every moment, that we may beg His assistance for knowing His will in things doubtful, and for rightly performing those which we plainly see He requires of us, offering them to Him before we do them, and giving Him thanks when we have done." (Fourth Conversation)
"There is not in the world a kind of life more sweet and delightful than that of a continual conversation with God..... It is not pleasure which we ought to seek in this exercise; but let us do it from a principle of love, and because God would have us.... Ah! knew we but the want we have of the grace and assistance of God, we should never lose sight of Him—no, not for a moment." (Fifth Letter)
"It is, however, necessary to put our whole trust in God, laying aside all other cares, and even some particular forms of devotion, though very good in themselves, yet such as one often engages in unreasonably, because these devotions are only means to attain to the end. So when by this exercise of the presence of God we are with Him who is our end, it is then useless to return to the means; but we may continue with Him." (Sixth Letter)
"She seems to me full of good will, but she would go faster than grace. One does not become holy all at once." (Ninth Letter)(That last letter could have been written about me, so strongly does it hit me!)
"Pray remember what I have recommended to you, which is, to think often on God, by day, by night, in your business, and even in your diversions. He is always near you and with you; leave Him not alone. You would think it rude to leave a friend alone who came to visit you; why, then, must God be neglected? Do not, then, forget Him, but think on Him often, adore Him continually, live and die with Him; this is the glorious employment of a Christian. In a word, this is our profession; if we do not know it, we must learn it." (Tenth Letter)
