Peddlers of a false Gospel had, among other things, accused Paul to the Corinthian church of preaching for reward. In this letter Paul reminds the church of how he ministered among them when he was there. He took no money from them and neither did they provide for him in other ways. He writes in this letter that he either provided for by himself or he was provided for by other churches. He chose to forgo the right to their providing him so that he would not be accused in this way. Ending his response to the accusation he leaves his readers with these two primary motivations for ministry; he doesn’t want their money but he does want to edify the church.
His accusers were likely doing the very thing of which they accused him. This is a common ruse of Satan and those who serve him. Before they are rightly accused of some wrong doing they falsely accuse those they wish to discredit. We observe this in politics and business; in fact in any sphere of life including, sadly, the church. When a person thinks they are about to be exposed they accuse the other of the very thing so as to create confusion and attempt to divert attention from themselves.
Paul had been accused of using religion to manipulate people to serve him and gain reward when in fact this was the motivation of those who accused him. They were jealous of the people’s affection for Paul. In his reluctant defense Paul explains his motivation is not to manipulate to receive but to minister by giving and building up the church.
In 1 John 3:1 John encourages his readers to take time to seriously consider the kind of love that God has lavished on us. His kind of love is one that gives, not takes, and that is the kind of love that Paul had shown to the Christians at Corinth. He was saddened that they were so easily deceived by the peddlers of false teaching when they could easily have seen through their ruse.
His motivation for ministry is the only motivation that is faithful to the Lord Jesus Christ, that is, love expressed in these two things: desiring the eternal benefit of others (v 14) expressed in building up other believers through personal sacrifice (v 19; 13:10).
