The Exodus event defined a people of God. God continues to lead us on, despite our resistance and revolt:
The exodus event, Israel’s journey towards the promised land, is also reflected in the spirituality of pilgrimage: the pilgrim is well aware that “there is no eternal city for us in this life” (Hb 14, 14), and that beyond the immediate objective of a particular shrine and across the desert of life, we find our true Promised Land, in heaven.
I think I’ve mentioned this before: a friend once said that everything in the Bible is either a Creation or an Exodus. That is why those readings are so central to the Easter Vigil. I wonder if every event of a Christian life can be boiled down as such. I don’t know, but I do look for Creation or Exodus, especially the latter in the various adventures God gives.
