Our apostle having commemorated the goodness and power of God in former deliverances, and expressed his assurance of present and future deliverances, doth in this verse excite and exhort the faithful at Corinth to help and further him with their prayers. You also helping together by prayer for us.
Where observe, The humility of the apostle in desiring the people's prayers for himself. Such as are most eminent in gifts and office, yea, and in grace too, do really want, and heartily desire, the help and benefits of their prayers who are far inferior to them in the church of God. And verily the people do owe unto their spiritual guides, as a debt of service, their earnest prayers for them; herein they are not only serviceable to them, but kind to themselves.
Observe farther, The great reason why St. Paul was so desirous of the Corinthians prayers; that deliverance and mercy being obtained by us, it is our duty by praise and thanksgiving to acknowledge the same to God. What is obtained by prayer, should be owned by thankfulness; God forbid we should be clamorous in asking favours, and dumb and tongue-tied in returning thanks.
