The prophet Isaiah says, “Your iniquities have separated you from your God; and your sins have hidden His face from you.” This is the separation that has been removed for us by our Lord. This is the wall of enmity that has disappeared – the wall of our sins.
"(You are) built upon the foundation of the apostles and prophets, Christ Jesus Himself being the cornerstone, in whom the whole structure is joined together and grows into a holy temple in the Lord; in whom you also are built into it for a dwelling place of God in the Spirit." By breaking down the wall, the Lord reuses us, the bricks, in a new structure. He creates from us a temple for the Holy Spirit, Whom we know, Who is our Comforter, Who lives in and among us, to Whom we pray always that He will "come and abide in us," we who are held together, made fast by the Cornerstone, Jesus Christ!
