The best way to reinforce your progress in fulfilling God's purposes for your life is to keep a spiritual journal. This is not a diary of events, but a record of the life lessons you don't want to forget. So take the time to reflect, discuss what you read each day, and then journal your thoughts in this companion to the book: The Purpose Driven Life by Rick Warren.
