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

Read 1 Corinthians 9:17 Using Other Translations

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.
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 were doing this on my own initiative, I would deserve payment. But I have no choice, for God has given me this sacred trust.
