Paul's words here are a reflection of his commitment to the mission of spreading the Gospel. By saying he "robbed" other churches, he uses strong language to emphasize that he accepted financial support from other congregations to ensure that the Corinthians would not be burdened by his needs. This choice of words is not literal but rather a rhetorical device to stress the sacrifice and dedication involved in his ministry.
Paul's approach demonstrates his desire to remove any obstacles that might hinder the Corinthians from receiving the message of Christ. By not asking for financial support from them, he ensures that their focus remains on spiritual matters rather than material concerns. This also illustrates the early church's practice of mutual support, where different communities would aid one another to further the mission of spreading the Gospel. Paul's actions highlight the importance of selflessness and the willingness to make personal sacrifices for the benefit of others, a core principle in Christian teachings.
