in the quarry

Week 17  Psalm 118

Near the end of the psalm it says: the stone rejected by the builders has now become the cornerstone. This is the Lord’s doing, and it is marvelous to see.
If I’m reading psalm 118 for the very first time this is one of those “what’s-this-all-about?” verses. But I’ve read psalm 118 before. I decide to check a couple of the cross references to the NT.
In Matthew the Lord’s talking to some (unfriendly) people and he asks them about this exact verse. Asks them if they’d read it. Quoted it: the stone rejected by the builders has now become the cornerstone.
The same story’s in Mark: the stone rejected by the builders has now become the cornerstone.
And Luke: the stone rejected by the builders has now become the cornerstone.
Peter quotes it this way: the stone that you builders rejected has now become the cornerstone.
So the NT expands on the OT. Fills-in a blank.
But even if the only thing I’ve got is psalm 118 I can still catch the drift. Some stone masons went to a quarryman. They combed through the quarry searching for a cornerstone. Which one? Block A or Block B? They decided to reject Block A. Chose Block B to build on.
From psalm 118 I can dope-out that they made a bad choice in taking Block B and discarding Block A. But it’s from the NT that I see how huge their gaff was.
