A sound body

I think that when we neglect our bodies, under the mistaken impression that they have no role in spiritual warfare, it’s like an F-1 driver deciding that he’s too good a driver to need a well maintained car. Recognizing that we should break any of these rules when charity demands, I’d still say that the following seem about as fundamental as oil changes:
1. Sufficient, but not excessive sleep.
2. Daily exercise, even for just a few minutes.
3. Healthy meals.
I don’t know how fundamental this one is, but I do think it helps:
4. Independence from caffeine. (NOT complete abstinence!)
God certainly exempts some of his saints from some of these requirements, sleep for example, but it’s pride to presume that he’ll do the same for us.
