Continuing on with my notes from How To Say No to a Stubborn Habit by Erwin Lutzer:
Chapter 13, Writing the Last Chapter
This chapter is titled thus because the last step is what we do with what we have learned. Lutzer suggests getting a notebook which will become a spiritual diary and including in it such things as letters to God about our failures, weaknesses, bad habits, desires, etc.; prayer requests and answers; strategies for our growth in grace (spending time in the Word, verses to memorize, etc.); anticipating ways Satan might try to trip us up and preparing for them; observations from Scripture; lessons learned.
(Disclaimer: My purpose in jotting down these notes is not to post "the answer" so that people don't have to buy the book: on the contrary, I hope anyone struggling with persistent sin will buy the book. There is so much more there that is so rich. Rather, this is just an exercise for me to review what I have read and studied.)
