Matthew 16:21-17:9

Jesus is preparing his disciples to be the church, and so he starts to tell them about what is going to happen to him on the cross, and God's plan through it all.  Then he takes three of them to the top of a mountain and shows them who he truly is, being transfigured before them and shining with the glory of God.  God doesn't leave us to follow him blindly, he wants to reveal himself to you and show you who he is!
