Who is Jesus: Who gets to answer this question in our day?

This is the first time I've used this site to solicit sermon insights. Yours are welcomed!

I'm working on a sermon for this weekend. Nicodemus comes to Jesus observing that Jesus must be from God, for no one could do the stuff Jesus is doing if God weren't with him.

I'm thinking of the many ways that people come to explore the person of Jesus today. How would they begin their exploration? To whom would they turn?

I'm also wondering about the responses people get to their questions about Jesus.

Any comments?
