1 Corinthians 9:17

For if I do this of my own will , I have a reward , but if not of my own will , I am still entrusted with a stewardship .

If I preach voluntarily, I have a reward; if not voluntarily, I am simply discharging the trust committed to me.

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.
