Here the apostle answers an objection, which without any just cause was made against him by some: it was suggested, "that though he was not burdensome to the Corinthians himself, nor took any thing of them for preaching the gospel, yet that he cunningly and craftily sent others to them, and set them at work to take money for him."
Now, to wipe off this aspersion, the apostle appeals to themselves, whether any person he ever sent to them received any thing of them for his use? Neither Titus nor Luke made a gain of them, but with the same generosity and freedom preached the gospel, and communicated the riches of grace to their souls.
When the ministers of the gospel at any time call in the assistance of others to help them in their work, their care is to employ such, as near as they can judge, who are of the same spirit, and walk in the same steps, with themselves.
St. Paul, Titus, and Luke, all agree together in carrying on a generous design for the preaching the gospel to the Corinthians freely, and are of the same mind and practice in every thing.
