Phil. 2:20 For I have no man likeminded, who will naturally care for your state.
21 For all seek their own, not the things which are Jesus Christ’s.
2 Cor. 12:14 – for I seek not yours, but you
1 Cor. 9:15 But I have used none of these things: neither have I written these things, that it should be so done unto me: for it were better for me to die, than that any man should make my glorying void.
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!
from the apostle Paul, the non-mercenary!
