My New Favorite Book
Format: Paperback
I thought I was pretty good on identity, but this book took it to a whole new level. The #1 book I would recommend to anyone wanting to change their life, step more into who they are, grow closer to God, really basically to anyone. It is going to be my book club’s next read. I will say, it looks like it would be a quick read, but don’t read it quick. You’ll miss so much. Savor it.

From the field to the palace
Format: Paperback
Very good read. I recommend it. David was GOD'S KING. He wanted to build GOD a temple, but couldn't. It took another king to build David a palace, because he probably would have built himself a shack. That's where he came from. A good read
