The saying about health everyone is most familiar with is “health is wealth.” That is indeed true, and the Bible has a few verses that talk about health in relation to service. If we look at things from a certain perspective, health is simply the condition of our human body.
Even in the Book of Genesis, God made it clear that there should be a day to rest, not just for the land, but also for the body. When the Israelites failed to rest in farming the land, they were forced out of the Promised Land.
In the New Testament, health is needed in order to be used mightily by God in a specific ministry. While there were a few Bible characters who had problems with their health, they continued on with the task God called them to do. If we want to please God, let us take care of our bodies.
