John Calvin Commentary 2 Corinthians 11:29

"Who is weak, and I am not weak? who is caused to stumble, and I burn not?" — 2 Corinthians 11:29 (ASV)

Who is weak. How many there are who allow all offenses to pass by unheeded — who either despise the weaknesses of fellow believers or trample them underfoot! This, however, arises from their lack of concern for the Church. For concern undoubtedly produces συμπάθειαν (sympathy,) which leads the Minister of Christ to share in the feelings of all, and to put himself in the place of all, so that he may adapt himself to all.
