I find a few things about John 7 to be interesting.
Timing. Note the reference in v.6 "My time is not yet here." That's familiar. Jesus said in John 2, regarding his mother's request for a miracle, "My hour has not yet come." (2:4). And later, the authorities were somehow restrained from seizing Jesus because 'his hour had not yet come." (v.30) John is concerned about timing and wants us to know not only who Jesus is, but also that God has a plan worked out and a timing schematic laid out for that plan.
Living Water. Note the reference in v.37-38 and how similar the symbolic meaning of water is to 4:10-14.
The World's View of Christ Followers. I find Jesus' statement in v.7 to be somewhat perplexing. Speaking to his disciples, he says, "the world cannot hate you..." Really?
Not Going Public. The disciples want Jesus to 'go public'. But Jesus isn't ready. He avoids Judea, goes to the Festival 'in secret' (v.10). How, exactly, an electrifying figure like Jesus 'secretly' goes to a party is worth pondering. And why? That's worth asking, too.
Who Is Jesus? John 7 has a recurring question throughout: Who is Jesus? Is he a good man (v.12)? Is he demon possessed (v.20)? Messiah (v.26, 41)? The Prophet (v.40)? This is THE question that John deals with in his Gospel, and it is underneath of the entire writing. From the very beginning of Chapter 1, John wants to tell us who Jesus is, and he wants us to know that people are divided over the question of identity.
Who do YOU believe Jesus is? That's the question.
Note the ending of Chapter 7 as Nicodemus shows up again. He was in chapter 3 creeping around in the dark and we will see him again.
