St. Paul shows the integrity with which he had preached the Gospel of Christ, Co2 4:1, Co2 4:2. And that, if it was unprofitable to any who had heard it, it was because their unbelieving hearts were blinded, Co2 4:3, Co2 4:4. How he preached, and how he was qualified for the work, Co2 4:5-7. The troubles and difficulties he met with in his labors, and the hope and consolations by which he was supported, Co2 4:8-15. And the prospect he had of eternal blessedness, Co2 4:16-18.
