Musclar Atrophy and Christianity

Kinda brain fried right now so this might not make a lot of sense. I'm sitting here in the library reading about muscular tissue in my anatomy textbook. The book talks a little bit about muscular conditions such as muscular atrophy and hypertrophy in the section regarding muscle fibers. In the case of muscular atrophy, muscles waste away from disuse. It often happens to patients that are bed or cast ridden for an extended period of time. Myofibrils waste away and the size of muscle fibers decreases as a result. I couldn't help but think that our faith is very much the same.
In James 2 (of which I already blogged about), the idea "faith without deeds is dead" comes about. When we don't apply our faith to our lives, our faith is pretty much useless. We we are not constantly walking with the Lord, seeking Him in every situation, and stepping out in our faith, it begins to wither. When we rely on ourselves rather than God in tough situations, our faith is little and no where to be found. Don't let your knowledge that Jesus is Lord waste away. Even demons know that Jesus is Lord. What sets us apart is the faith that we have. Our faith in God, His word, and His promises should lead to a changed lifestyle.
