1 Corinthians 9:15-18
15But I have aused none of these things. And I am not writing these things so that it will be done so in my case, for it would be better for me to die than have anyone make bmy boast an empty one. 16For if I proclaim the gospel, I have nothing to boast, for aI am under compulsion. For woe is me if I do not proclaim bthe gospel. 17For if I do this voluntarily, I have a areward; but if against my will, I have a bstewardship entrusted to me. 18What then is my areward? That, when I proclaim the gospel, I may offer the gospel bwithout charge, so as cnot to make full use of my authority in the gospel.
