Luke 13:29-30
And people will come from east and west, and from north and south, and recline at table in the kingdom of God. And behold, some are last who will be first, and some are first who will be last.
Some are last who will be first,
and some are first who will be last.
This lesson is one which I find extraordinarily deep. Particularly the application in Matthew 20:16, which always confused me as a child.
Faith; not works.
