The apostle apologizes for expressing his jealousy relative to the true state of the Corinthians; still fearing lest their minds should have been drawn aside from the simplicity of the Gospel, Co2 11:1-3; From this he takes occasion to extol his own ministry, which had been without charge to them, having been supported by the Churches of Macedonia while he preached the Gospel at Corinth, Co2 11:4-11. Gives the character of the false apostles, Co2 11:12-16. Shows what reasons he has to boast of secular advantages of birth, education, Divine call to the ministry, labors in that ministry, grievous persecutions, great sufferings, and extraordinary hazards, vv. 16-33.
