Saint Therese of Lisieux: A Gateway

For St. Therese every day was a day of profound thanksgiving.  One day she told her sister Celine:

It is the spirit of gratitude which draws down upon us the overflow of God's grace, for no sooner have we thanked Him for one blessing than He hastens to send us ten additional favors in return.  Then, when we show our gratitude for these new gifts, He multiplies His benedictions to such a degree that there seems to be a constant stream of divine grace ever coming our way.

This has been my own personal experience; try it out for yourself and see.  For all that Our Lord is constantly giving me, my gratitude is boundless, and I try to prove it to Him in a thousand different ways."

 (My Sister  Saint Therese, by Sister Genevieve of the Holy Face (Celine Martin).  Reprinted by Tan Books and Publishers, Rockford, Illinois, 1997, p. 97).

How can we live in this spirit of gratitude to God and show it?
