She girds herself with strength, and strengthens her arms. —Proverbs 31:17 (NKJV)
As a Christian, your body is the temple of the Holy Spirit, and you need to keep it in good condition so God can work through you the way He desires to. Being excessively tired can adversely affect us and our spiritual life. We don’t have the desire or stamina to pray as we normally would. We don’t present the best witness to others. It is even easier to be grouchy and unable to walk in the fruit of the Spirit when we feel tired most of the time.
I encourage you to make room in your life for exercise. In my own life, I am not where I need to be yet but I am making progress. I have finally decided that, to do what I can do is better than doing nothing at all. Find something you can enjoy and still get exercise. Try walking or playing a sport to get the exercise you need. Exercising with other people might work for you.
People who exercise regularly do tend to be more confident. For one thing, they feel better and more energetic, so they accomplish more and enjoy what they do. They usually look better, and that increases confidence. Exercise also relieves tension and stress, which will help anyone’s confidence. Don’t think about exercising anymore—just do it!
Lord, I acknowledge that my body is Your temple, and I want it to rightly reflect You. Help me to discipline myself and give my body the exercise it needs. Amen.
