1 Corinthians 3:8; 1 Corinthians 9:17-18
Now he that planteth and he that watereth are one: and every man shall receive his own reward according to his own labour.
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 .
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.
