"Or do you not know that your body is the temple of the Holy Spirit who is in you, whom you have from God, and you are not your own? 20 For you were bought at a price; therefore glorify God in your body and in your spirit, which are God’s." 1Corinthians 6:19-20
Gods desire for you is to be strong physically! He paid a high price for you spirit soul and body. When you realize you are Gods dwelling place, you get a revelation of the fact that you bring Glory to God when you are healthy. Take care of your body! Do all you can to honor your temple and trust God to do the rest.
