2. What is its value?

Keeping a journal can be a useful discipline because it encourages you to notice with care what is going on around you, how others respond to you, how you feel in different settings and how you see God at work. 

The act of writing slows you down and often gives you the opportunity to notice those things that most challenge you. 

A journal will work best when you are honest with yourself.   Most of what you write in your journal will not be seen by anyone else, but unlike a personal diary you may want to refer to it later when in conversation with others i.e. to talk about your life, pray together or when seeking wisdom about a decision you need to make.
