1 Corinthians 9:12-15

9:12 If others receive this right from you, are we not more deserving?

But we have not made use of this right. Instead we endure everything so that we may not be a hindrance to the gospel of Christ. 9:13 Don’t you know that those who serve in the temple eat food from the temple, and those who serve at the altar receive a part of the offerings? 9:14 In the same way the Lord commanded those who proclaim the gospel to receive their living by the gospel. 9:15 But I have not used any of these rights. And I am not writing these things so that something will be done for me. In fact, it would be better for me to die than – no one will deprive me of my reason for boasting!

1 Corinthians 9:18

9:18 What then is my reward? That when I preach the gospel I may offer the gospel free of charge, and so not make full use of my rights in the gospel.
