The book of Deuteronomy as we have it is a reshaping of Moses' words in light of the later experience of exile. We read of the hope that Moses was sharing and realize that, even after failure and loss, we are still offered hope.
The passage begins, "When you have come into the land that the Lord your God is giving you..." We aren't where we want to be, but Moses says that we're going to be.
A second point that was true for Moses' first audience, for the readers of the compiled Deuteronomy, and then for us as well: we won't get there by ourselves--we are going as a congregation, and the achievement is not due solely to our own efforts; rather, the Lord God is making a gift.
Now, what are we supposed to do with this gift? Not hide it or hoard it. Rather than ownership, we have assumed something more like trusteeship. We are supposed to use this gift to continue God's work.
In Moses' time, the distribution was through the priests. We still use the church as one of our conduits.
And not just do it--Moses commands us to say what we are doing, and why.
I'm trying to imagine a church service at offering time when all of us sitting in the pews might say something--either individually or together--as we put our money in the plate. Once again, I am grateful for the choir who takes care of this part for us. Yet, I can't quit wondering what I would say to help me remember that it is God's gift to me that I am sharing with others that day.
And who are these others? Moses reminds them that they themselves were immigrants in somebody else's country and that now that they are at home they need to celebrate with the immigrants who are now living among them. How do we celebrate our gifts with people we might consider to be not like us?
