Philippians 4:8 (NKJV)
When I was a child I was not so neat or organized, at least not as much as I am now. In the past there were times when my room was very messy and some things were hard to locate. At the time it did not matter to me where I put something because I knew generally where it was. As I grew older I learned that it is better to have things in order and to be organized because it is not only much easier to find things when they are needed but having things neat and organized is nicer than having things messy and cluttered. What I had to learn and practice was how to clear out the clutter.
One thing I learned in my process of becoming more neat and organized was that I had to part ways with some things and not hang on to everything forever. I also learned that I had to be diligent with myself to continue doing what I knew needed to be done or I would slide back into the world of messy and cluttered. This is exactly the same way we as Christians need to work on renewing our minds. The Bible has a lot to say about the mind and it even gives us the guidelines we need to know what thoughts to keep or remove and how to continue having the right kind of thoughts for the rest of our life.
People often have problems in their minds because they do not think on the right kinds of things; God's Word will help us get the clutter and mess of wrong thoughts out of our minds. Our thoughts need to be continuously monitored to make sure any wrong thoughts do not get into our thinking. Wrong thoughts lead to the wrong kinds of words and actions so right and godly thoughts are vital to living the kind of life God has planned for us. We all need to have a steady diet of the Word of God to help us have the right thoughts and to identify the wrong kinds of thoughts.
