An essential reply...and something about a rock.

What's that about?

"Who do you say that I am?" Jesus asked.

Before that crucial question, there were dozens of clues: the rock that sheltered Moses when he asked to see the face of God, the rock that gushed water for a million thirsty migrants, the rock that formed a solid foundation, and the rock that trips people.

Simon Peter got the answer out.

"You are the Christ, the Son of the Living God!"

And on this great rock, this great realization, Jesus said, "I will build my church."

And there it is, the Shekinah--the glory of God!
