To begin with, here is a link to the blessing we read at the start of last week's bible study meeting, entitled, "Blessing When the World Is Ending" by Jan Richardson. As we get deeper into the weeds of the sermon on the mount, I think Richardson's blessing is a great place to return to for orientation. In Matthew's Gospel, the unthinkable has already happened (the loss of the temple, the murder of the infants, etc.), so that this blessing aligns well, I think, with what Matthew is aiming at articulating in the Gospel.
This week we'll move on to Matthew 5:17-37. It might be helpful to read the entire Sermon on the Mount if you haven't done so already. That would mean starting at chapter 5:1 and ending at 7:29. As any literary unit, a sermon is difficult to take piece by piece, so that returning to a broader reading can be helpful as we look at individual pieces of the sermon.
If you're interested in other reading, check out Luke's Sermon on the Plain (Luke 6:17-49). As we've seen before, Luke and Matthew share a lot of material, and the sermon is one place where they head in different directions.
