Charles Ellicott Commentary 2 Corinthians 6:13

"Now for a recompense in like kind (I speak as unto [my] children), be ye also enlarged." — 2 Corinthians 6:13 (ASV)

Now for a recompence in the same.—Better, perhaps, as a return, as expressing the idea of reciprocity. Children should requite the care and love of parents. (Compare to 2 Corinthians 12:14.) They, the Corinthians, are his spiritual children. (Compare to 1 Corinthians 4:15.) What does he demand of them, but that they should love him in return for his love? What they needed in their spiritual life was breadth and expansiveness of affection.
