For I take no special pride in the fact that I preach the Gospel. I feel compelled to do so; I should be utterly miserable if I failed to preach it. If I do this work because I choose to do so then I am entitled to a reward. But if it is no choice of mine, but a sacred responsibility put upon me, what can I expect in the way of reward? This, that when I preach the Gospel, I can make it absolutely free of charge, and need not claim what is my rightful due as a preacher. For though I am no man’s slave, yet I have made myself everyone’s slave, that I might win more men to Christ. To the Jews I was a Jew that I might win the Jews. To those who were under the Law I put myself in the position of being under the Law (although in fact I stand free of it), that I might win those who are under the Law. To those who had no Law I myself became like a man without the Law (even though in fact I cannot be a lawless man for I am bound by the law of Christ), so that I might win the men who have no Law. To the weak I became a weak man, that I might win the weak. I have, in short, been all things to all sorts of men that by every possible means I might win some to God. I do all this for the sake of the Gospel; I want to play my part in it properly.
Even though I am free of the demands and expectations of everyone, I have voluntarily become a servant to any and all in order to reach a wide range of people: religious, nonreligious, meticulous moralists, loose-living immoralists, the defeated, the demoralized—whoever. I didn’t take on their way of life. I kept my bearings in Christ—but I entered their world and tried to experience things from their point of view. I’ve become just about every sort of servant there is in my attempts to lead those I meet into a God-saved life. I did all this because of the Message. I didn’t just want to talk about it; I wanted to be in on it!
that also means that I am free of obligations to all people. And, even though no one (except Jesus) owns me, I have become a slave by my own free will to everyone in hopes that I would gather more believers.
