I overheard a conversation in Asia. One asked about how a certain work was going to be done. The reply was, “That is not our headache. It is the contractor’s responsibility; let him take care of it.” On one level, that is not an unreasonable response. We might have better stated it, “It is not really our business, let him do the job his way.” But in the context of the conversation the attitude of the responder was basically, “I don’t care – let them handle their own problems without my help.
Although Paul did not please men, he sought to remove all barriers to the gospel. At times, he refused to receive financial help, so others would not think ill. He commended himself as God’s servant, v. 4.
