Like a lot of people posted, one of my favorite books is James and I once heard of a guy (a friend of a friend from bible study) that memorized it. I thought, gee that's cool, but I could never do it.
Lately, with my relatively new job, I walk a lot and I started to jot down James on index cards and although it ebbs and flows how far I can get in Ch 3, I got the first 2 chapters down now.
So I just want to challenge everyone, if they aren't already doing this, to give memorizing entire chapters of their favorite book! If you don't think you can do it, He may surprise you. The best is discovering, if you get out of the habit for a few days, how much comes back to you.
