I'm currently using a book called "The Valley of Vision" during my prayer time each day. It's a collection of Puritan prayers that quickly make the reader realize how shallow his or her prayer life has been.
One section from a prayer I read today says: "The greatest injury is in the having, the greatest good is in the taking away. In love divest me of blessings that I may glorify thee the more."
My prayers don't typically include requests for God to remove blessings from my life so that I can glorify him more, but this particular prayer rings so true that I need to rethink my prayer life. Abundance often causes complacency. Lack often causes dependency upon God. Recognizing that truth is one thing. Praying for it is another.
