The Stricture says that your body is the temple of the Holy Sprit “Don’t you realize that your body is the temple of the Holy Spirit, who lives in you and was given to you by God? You do not belong to yourself,” (1 Corinthians 6:19). We are commanded to honor the Lord with our bodies. How do you do that? You take care of it. You respect it. You treat it as valuable. You use your body to bring Him glory “They were made for the Lord, and the Lord cares about our bodies” (1 Corinthians 6:13) “Don’t you realize that your bodies are actually parts of Christ?” (1 Corinthians 6:15). When you stand strong against temptation, you are honoring the Lord with your body. When you take care of yourself by eating properly and getting enough sleep, you are honoring the Lord with your body.  There is no doubt that being in shape spiritually is the most important kind of fitness.
