I Am Jealous For You With Godly Jealous

To preserve the Corinthians from being corrupted by the insinuations of the false apostles, he tells them he was jealous over them with godly jealousy; he was afraid lest their faith should be weakened by hearkening to such suggestions as tended to lessen their regard to his ministry, by which they were brought to the Christian faith. He had espoused them to one husband, that is, converted them to Christianity (and the conversion of a soul is its marriage to the Lord Jesus); and he was desirous to present them as a chaste virgin-pure, and spotless, and faithful, not having their minds corrupted with false doctrines by false teachers, as Eve was beguiled by the subtlety of the serpent. This godly jealousy in the apostle was a mixture of love and fear; and faithful ministers cannot but be afraid and concerned for their people, lest they should lose that which they have received, and turn from what they have embraced, especially when deceivers have gone abroad, or have crept in among them. - Matthew Henry
