[CHRYSOSTOM] (Co2 1:11; Co2 9:11-12). The Greek is susceptible also of this translation, "That grace, being made the greater (multiplied) on account of the thanksgiving of the greater number (for grace already received), may abound (abundantly redound) to," &c. Thus the Greek for "abound" has not to be taken in an active sense, but in its ordinary neuter sense, and so the other Greek words. Thanksgiving invites more abundant grace (Ch2 20:19-22; Psa 18:3; Psa 50:23).
