Walls …
Here’s what the Apostle Paul wrote about dividing walls (Eph. 214):
For [Christ] himself is our peace, who has made the two one and has destroyed the barrier, the dividing wall of hostility … His purpose was to create in himself one new humanity out of the two, thus making peace, and in this one body to reconcile both of them to God through the cross, by which he put to death their hostility. He came and preached peace to you who were far away and peace to those who were near.
