2 Corinthians 9:15

For his unspeakable gift. Such is the conclusion, which the apostle puts to the subject upon alms-deeds. In the following chapter he proceeds to a new subject; but first thanks the Almighty, that he has enriched the Corinthians with so charitable a disposition. St. John Chrysostom, Theo., and some other commentators think, that by the expression, his unspeakable gift, is meant the incarnation of Christ. The fruit of alms-deeds is the increase of grace in all justice and good works to life everlasting; God granting these blessings for a reward and recompense of charitable works, which therefore are called the seed, (ver. 10. above) or meritorious cause of these spiritual fruits.
