God alone is good - so who's Jesus?

I recently received this question:

Jesus said only God is good. Doesn't that mean that he isn't God? (The question refers to Mark 10:18 and following.)

Here's the answer:

No - it means Jesus was asking his questioner who he thought he was. In other words, Jesus was saying something like, "Only God is good - so who do you think I am?"

Then, Jesus tells this guy that eternal life will be received by following him. Think about that. If you want to get to heaven, follow me, I'm on my way. Or in other words, if you want to get to heaven, you have to submit to my teaching.

He goes even further when he says that so many good things must be given up to have him when he says that everyone who has left things for his sake, and for the gospel's, gets eternal life.

So he's saying, if you count gaining me as worthy of losing everything, you'll get eternal life.

So Jesus is our reward, our treasure, the life-giver, and the one whose teaching is pure and good.

And this man was left with the question, "Who is he?"

This passage doesn't explicitly teach that Jesus is God. But it only works if he is.

And we're all left with the same question: who is Jesus? And is he worth following?
