Being spiritually well off includes realizing and fully accepting the fact that our body is the temple of the Holy Ghost, and we are no longer our own. This means that the first criterion in our decisions is to choose things that are pleasing to God. We are told to glorify God in our body, which includes taking care of its physical well being. Making bad choices can make you sick. Choosing destructive habits and behaviors are among the bad choices that make people sick. God has power to heal supernaturally, and He certainly has a track record of doing so, but we have to wonder how it sounds to God when we pray for physical wellness, while at the same time, abuse our body through foolish behaviors. If it’s raining in your house, the first thing to do is close the window!
