For the majority of this Chapter Paul has a central theme; you’re body is important to God. Its purpose is to honor God, its the temple of the Holy Spirit and its not for us to use up for our own enjoyment. Verse 20 takes it from the narrow application to the much more broad principle: You are not your own! I forget that constantly. Its not just limited to our physical body; it extends to our time, our talent, our money…. we are not our own. What part do you hold back?
