(Pro 10:14 KJV) Wise men lay up knowledge: but the mouth of the foolish is near destruction.
My family has a lot of books. Books to us are like dust to Pigpen. A good illustration of this is a characteristic of our trips to Hawaii. We discovered the Friends of the Library on Maui. They had a tin shack out in the cane fields with books piled all over the place. We were in hog heaven. At ten cents a book we would buy anything that looked interesting. We would end up shipping home apple boxes filled with books every time we visited.
Having said that, I have a shelf on which I keep my treasures, my sources of wisdom. There are a few select books, in addition to the Bible, that I try to re-read every few years. An example? How about Mere Christianity by C.S. Lewis. I “store” (6845) the knowledge I need to supplement my quest for wisdom. I don’t get it confused with the light entertainment that I find in the “new books” section of the library.
So? Let’s assume you are reading your Bible. Are you setting aside other tools? Are you in a constant search for knowledge that will help you be one of the upright? If not, it might be a good idea to start.
