Trustful Surrender to Divine Providence: The Secret of Peace and Happiness: Father Jean Baptiste Saint-Jure, Saint Claude de la Colombiere.
My spiritual guide recommended this book to me a couple of years ago, and I am so glad she did. It is one of the best spiritual books I have read, and I have practially worn out my first copy, so I purchased a second one. (I got them both on eBay, but you can also purchase them from TAN Books).
Here is an excerpt:
"To remain indifferent to good fortune or to adversity by accepting it all from the hand of God without questioning, not to ask for things to be done as we would like them but as God wishes, to make the intention of all our prayers that God's will should be perfectly accomplished in ourselves and in all creatures is to find the secret of happiness and content."
