I have been reminded recently of this truth—that our body is the temple of the Holy Spirit. And because of this fact, we ought to flee from all that defiles this temple, mainly sexual immorality.
Flee immorality. Every other sin that a man commits is outside the body, but the immoral man sins against his own body. 19 Or do you not know that your body is a temple of the Holy Spirit who is in you, whom you have from God, and that you are not your own? 20 For you have been bought with a price: therefore glorify God in your body.I Corinthians 6:18-20
If any man is serious about his own purity, this passage is one of the best to memorize and take it to heart. I found that it helps in my studying of it to go over it backwards. Let me show you.
From verse 20. God bought me with the price of His own blood. So, He owns me. I am His property. Hence, He has given me access to this body, and I am its steward. And when I am found to be a good steward, I am honoring Him.
From verse 19. Here is more about this body: I can call it my body because God has purchased it for me and given it to me. The purpose of this body is to house God’s Spirit. My body is called a temple, the temple where His Holy Spirit dwells. He lives in me.
From verse 18. Now in light of this truth, I must do all I can to take care of this body. But there is a grave danger to it that I must be aware of and guard against. It is sexual sin. All other sins are outside of the body, but immorality is a sin against the body (and who knows how many ways it goes against my body). Therefore, I must flee from this sin. It is the only way to fight against it. I cannot try to fight with it and overcome it. If I try that, it will always deceive me and trap me. No, nothing I do will work to destroy this sin. I must run from it. That is the only way of escape. It is the only way to keep my body (the body that God gave me) clean and pure and honoring to Him.
