We're living stones, being built up into a spiritual house...
I grew up in New England. When the farmers cleared the field, they dug up a lot of rocks. Rocks, rocks, everywhere. What to do with the rocks? Make a border wall out of them.
Our house was a small Cape Cod, a 100 year old cottage. The front of our house had a very long rock wall of old rocks that had been unearthed from the fields. By the 1960s the wall was falling down and it needed to be rebuilt
The old guys had the rocks strewn all around. One of them would pick up a rock and test it, and look at it closely, turning it over and over. Feeling it all around with his hands, brushing off the sand and dirt, he'd put it next to the rock on the wall, and see if it fit. Nope. He'd pull it out and talk to the other Italian guy for a while, and after some talk, and laughter, taking their time, he would pick up another rock, and test it all over again.
Gradually, slowly, the wall took shape. Long and straight, it stands to this day.
He is the Rock, the Chief Cornerstone...
"As you looked, a stone was cut out by no human hand, and it struck the image on its feet of iron and clay, and broke them in pieces." (Daniel 2:35)
"For it stands in Scripture: “Behold, I am laying in Zion a stone, a cornerstone chosen and precious, and whoever believes in him will not be put to shame.”" (1 Peter 2:6).
He is the chief cornerstone, but having the Spirit in us, our souls are so intimately tied with Him that we also are stones. Little stones from the Rock. And here comes the pun: we are chips off the old block.
Bishop of Lincoln Robert Sanderson is said to have said it first in a 1637 sermon:
"Am not I a child of the same Adam ... a chip of the same block, with him?"
We are of Adam, but our precious Lord didn't leave us on the stone quarry floor. He picked us up, adopted us, polished us, built us up "to be a holy priesthood," and set us in His spiritual House. Praise His merciful name, His grace is so generous!
