Jesus took Peter, James, and John up on a mountain with him, and there, Jesus was transfigured before them. Moses and Elijah even appeared and spoke with Him. Peter, though terrified, recognized that this was a good moment, and wanted to set up camp, but Jesus told them not to tell anyone what they had seen and heard until after He had risen from the dead. Why keep the transfiguration a secret? Why not "set up camp" here in this moment? Because Jesus' glory is revealed on the cross. We don't get the God of the transfiguration without the God of the cross. We "set up camp" at the cross and the empty tomb.
