Jesus had a nickname for the apostle John, and so do I.
To Jesus, he was a Son of Thunder. But to me, he's Johnny One Note. That's because he repeats himself more than any other New Testament writer. In fact, sometimes the book of 1 John sounds like a broken record.
The question is, why did the Spirit of God inspire John to keep repeating himself? Might it be because He knew how thick the skulls of his readers would be? No doubt you have already heard what John will be repeating to us in 1 John 4:7-12. But how well have you been listening? I pray you'll come with ears to hear, again, Johnny's one note.
