Verse 18. What is my reward then? What is the source of my reward? or what is there in my conduct that will show that I am entitled to reward? What is there that will demonstrate that my heart is in the work of the ministry; that I am free and voluntary, and that I am not urged by mere necessity? Though I have been called by miracle, and though necessity is laid upon me, so that I cannot but preach the gospel, yet how shall I so do it as to make it proper for God to reward me as a voluntary agent? Paul immediately states the circumstance that showed that he was entitled to the reward; and that was, that he denied himself, and was willing to forego his lawful enjoyments, and even his rights, that he might make the gospel without charge.

I may make the gospel of Christ without charge. Without expense to those who hear it. I will support myself by my own labour, and will thus show that I am not urged to preaching by mere "necessity," but that I love it. Observe here,

(1.) that Paul did not give up a support because he was not entitled to it.

(2.) He does not say that it would be well or advisable for others to do it.

(3.) It is right, and well for a man, if he chooses, and can do it, to make the gospel without charge, and to support himself.

(4.) All that this case proves is, that it would be proper only where a "necessity" was laid on a man, as it was on Paul; when he could not otherwise show that his heart was in the work, and that he was voluntary and loved it.

(5.) This passage cannot be urged by a people to prove that ministers ought not to have a support. Paul says they have a right to it. A man may forego a right if he pleases. He may choose not to urge it; but no one can demand of him that he should not urge it; much less have they a right to demand that he should give up his rights.

(6.) It is best in general that those who hear the gospel should contribute to its support. It is not only equal and right, but it is best for them. We generally set very little value on that which costs us nothing; and the very way to make the gospel contemptible, is to have it preached by those who are supported by the state, or by their own labour in some other department; or by men who neither by their talents, their learning, nor their industry, have any claim to a support. All ministers are not like Paul. They have neither been called as he was, nor have they his talent, his zeal, or his eloquence. Paul's example, then, should not be urged as an authority for a people to withhold from their pastor what is his due; nor, because Paul chose to forego his rights, should people now demand that a minister should devote his time, and health, and life to their welfare for naught.

That I abuse not my power in the gospel. Paul had a right to a support. This power he might urge. But to urge it in his circumstances would be a hinderance of the gospel. And to do that would be to abuse his power, or to pervert it to purposes for which it was never designed.
