But that's only half the equation, the bad half. What's also true, what the resurrection teaches, is that, while nothing that is of God can avoid crucifixion, no body of Christ ever stays in the tomb for long either. God always rolls back the stone and, soon enough, new life bursts forth and we see why that original life had to be crucified. Resurrection follows crucifixion. Every crucified body will rise again.
Scripture is subtle, but clear.
It is, first of all, a place in the heart. Galilee is the dream, the road of discipleship that they had once walked with Jesus, and that place and time when their hearts had most burned with hope and enthusiasm. And they do go back, to Galilee, to that special place in their hearts, to the dream, to their discipleship. Sure enough, Jesus appears to them there. He doesn't appear exactly as they remember him, nor as often as they would like him to, but he does appear as more than a ghost or a mere idea.
