Why Did Jesus Say What He Said?

Why did Jesus teach the way he taught? Why did he say the things he said? I'm sure there are lots of answers to those questions.

This morning I found three reasons, in close proximity, that were pretty thrilling. They combine to paint a beautiful portrait of our Savior's love and goodness. Who wouldn't want to listen to this man?!

John 15:11:

These things I have spoken to you, that my joy may be in you, and that your joy may be full.

John 16:1:

I have said all these things to you to keep you from falling away.

John 16:33: 

I have said these things to you, that in me you may have peace. In the world you will have tribulation. But take heart; I have overcome the world.
