For indeed he accepted the exhortation; but being more earnest, of his own accord he went unto you.
All Commentaries on 2 Corinthians 8:17 Go To 2 Corinthians 8
John Chrysostom
AD 407
Observe how he also represents him as fulfilling his own part, and needing no prompting from others. And having mentioned the grace of God, he does not leave the whole to be God's; again, that by this also he may win them unto greater love, having said that he was stirred up from himself also. For, being very earnest, he went forth of his own accord, 'he seized at the thing, he rushed upon the treasure, he considered your service to be his own advantage; and because he loved you exceedingly, he needed not the exhortation I gave; but though he was exhorted by me also, yet it was not by that he was stirred up; but from himself and by the grace of God.'
