God wants the best for us in every sphere of our lives, even concerning our health. It takes good health to serve God efficiently. One of the things the devil does to prevent us to serve God as effectively as we ought to is by going after our health. Our well-being and physical health should be of great concern to us.
Prosperity does not only had to do with finances. There's also the kind of prosperity that concerns our health. We should not be too busy that we forget to look after our health. The real wealth is not just money but also being healthy, that is why people often say "Health is wealth".
Our walk with God should not be an excuse to why we should say we cannot take care and pay quality attention to our health. We do not have any excuses. Taking care of ourselves and maintaining a healthy lifestyle is not just for the good of ourselves, it's also for the benefit of our family and those close to us.
If we love truly love them we'll take care of ourselves so that at no point in time will they have a reason to worry about us or as a result of the poor state of our health.
