Lest you think I'm a bit crazy to say we should pump ourselves up and do so often throughout the day, the Bible puts it this way.
Philippians 4:8 tells us to think on pure, lovely virtuous, excellent truth and in fact to fix our mind on such thoughts. He wants us to dwell on truth, so it's not just me saying, "Pump yourself up!"
I had to remind myself several times yesterday as I trudged through my physical difficulties that He loved me and that He cared about my weaknesses and physical struggles. The cool thing is that not only was I reminding myself, I was reminding Him as well.
Philippians 4:4 is one that we almost speak without thinking. Rejoice in the Lord always. In light of this mindset, however, I believe that it gives a whole new meaning to rejoicing in the Lord. The truth is very good news. It is soothing to the soul. By repeating truth, by fixing it in my head, I remind my heart which does, indeed, delight us and gladden our hearts. It makes us look up and "gladden".
