I Corinthians 9

“For though I am free from all, I have made myself a servant to all, that I might win more of them” (v19).  Paul was so secure in his identity in Christ and his calling – to preach the gospel – that he could give up his “rights” and “become all things to all people” (v22).  As a minister of the gospel, he had the right to be supported financially and to even have a family (v5, 14), yet he willingly gave up those rights when necessary.  

“I do all for the sake of the gospel” (v23).  Being truly free means that we are not controlled by our desires or “rights” (v27) but are motivated by love for Christ and others.
