parallels and book-ends in Jn 21

I had caught two of these previously, but picked up two more:

1.) The first miracle of Jesus' ministry: Jn 2:1-11's water into wine. The last: Jn 21:2-11's fish out of water.

2.) The command/offer/exhortation to "follow me" begins and closes out the ministry of Jesus.

3.) The very interesting back-and-forth between Jesus and Paul in Jn 21:15-17-- Christ using agape the first two times, and all other references to love as phileo-- beautifully parallels the three-time denial of Jesus by Peter just before the crucifixion.

4.) The only two uses of the term translated "charcoal fire" are in Jn 18:18 and Jn 21:9.
