The lectionary pairs this psalm with the reading from 2 Kings (and by extension, then, with the gospel lesson for this week).
It's a reminder, one that we may well need, that we're living in God's kingdom and that we should be living according to God's intentions for us. The Lord's desire is for all to be fed and attended to. Those who care what the Lord wants will work toward these goals.
