ISB ~ 2 John 1 v4

some of your children:The implication of this statement is uncertain. Either John had made contact with only “some” of his readers, and these he found obeying the gospel, or else he implies that only “some” of those he encountered were doing well, while others were not. The absence of any rebuke in the letter, along with the general affirmation in verse 8, seems to favor the former interpretation.
