(“BSO” stands for Bible study outline. For an explanation of what I mean by that, see here.)
Do you recognize the same two ideas present in each of these five verses?
2 John 1:9
In each verse there is a reference 1) to Jesus’ teaching and 2) to His authority (e.g. “Lord” and “shepherd”). Thus Jesus relates to us as an authoritative teacher. Or we could say that He exercises His lordship through His teaching.
Look for themes when you read the Bible and let a verse here be commentary on a verse there.
