ISB ~ 2 Corinthians 7 v8

my letter:The severe letter that Paul had sent to Corinth by the hand of Titus. Although Paul wrote it with great anxiety (2:4), he was genuinely concerned for the well-being of the Corinthians and used this written form of correction as a loving means to elicit their repentance. He wanted to test their loyalty and see whether they would be “obedient” (2:9) to his fatherly authority by showing “zeal” (7:12) for him again. See note on 2 Cor 2:3.
