Ok, the title is a temptation to get you to read the post.
1Co 9:12 If others be partakers of this power over you, are not we rather? Nevertheless we have not used this power; but suffer all things, lest we should hinder the gospel of Christ.
1Co 9:14 Even so hath the Lord ordained that they which preach the gospel should live of the gospel.
1Co 9:16 For though I preach the gospel, I have nothing to glory of: for necessity is laid upon me; yea, woe is unto me, if I preach not the gospel!
1Co 9:17 For if I do this thing willingly, I have a reward: but if against my will, a dispensation of the gospel is committed unto me.
1Co 9:18 What is my reward then? Verily that, when I preach the gospel, I may make the gospel of Christ without charge, that I abuse not my power in the gospel.
1Co 9:23 And this I do for the gospel‘s sake, that I might be partaker thereof with you.
