Sounds like a strange question for a minister to ask, but I'd really like to know. We get a glimpse from the gospels as to what he was like (i.e. loving, compassionate, full of grace, accepting, etc.), but I want to know more. Did he have a sense of humor? I would think he would have to, because if he didn't, he would have killed his disciples after about a year with them. Was he nice? We generally like to think of Jesus as nice, but frankly, some of the stories of him in the gospels show a man who said scathing things against the Roman Empire and against the hypocrisy of the religious leaders of Israel. Did he do stuff as a kid to earn the anger of his parents? Probably.
I've been thinking about all of this recently because I've been reading a book by Christopher Moore entitled, Lamb: The Gospel According to Biff, Christ's Childhood Pal. It's a fictional retelling of Jesus' life as told by his friend Levi, who is called Biff. Firstly, if you're a stuffy Christian concerned with correct doctrine, don't read the book. You'll miss the humor in it (of which there is plenty), and just get mad. I've read the book twice now and I like it because it causes me to think about what Jesus was like, especially as a kid. My guess is that he was mischievous like any other kid. He probably pulled pranks on his friends, had a boyhood crush, etc. Thinking of Jesus in this way only makes me love him more. I love to contemplate the human side of Jesus; the side that struggled with temptation, got into trouble as a kid, had his heart broken by his friends, that kind of stuff.
Don't get me wrong, I'm impressed by the healer Jesus, the Jesus who could walk on water, the Jesus who could rise from the grave, but I'm more impressed with the Jesus who touched lepers because he loved them and ate in the homes of those who were hated by society. Think about Jesus as a human being, not just as divine, and I think you'll find a Jesus that you never knew.
