John Calvin Commentary 2 Corinthians 12:15

"And I will most gladly spend and be spent for your souls. If I love you more abundantly, am I loved the less?" — 2 Corinthians 12:15 (ASV)

And I will most gladly spend—this, certainly, was evidence of a more than fatherly affection—that he was prepared to expend on their behalf not merely his efforts and everything in his power to do, but even life itself. Moreover, while they regard him with coldness, he nevertheless continues to cherish this affection. What heart, even if as hard as iron, would such ardor of love not soften or break, especially with such constancy? Paul, however, does not speak here of himself merely that we may admire him, but also that we may imitate him. Let all Pastors, therefore, learn from this what they owe to their Churches.
