The prior post touched 1 Corinthians 3. Ephesians 2 is another chapter about God’s New Testament building; verses 19-22 have many rich points about this building:
So then you are no longer strangers and sojourners, but you are fellow citizens with the saints and members of the household of God, being built upon the foundation of the apostles and prophets, Christ Jesus Himself being the cornerstone; in whom all the building, being fitted together, is growing into a holy temple in the Lord; in whom you also are being built together into a dwelling place of God in spirit.
“In whom” (twice) and “in the Lord” tell us that the building is in Christ Jesus Himself and the building work takes place in Him. The dwelling place of God is in Christ Jesus, who is the embodiment of God (Colossians 2:9).
It is of God (not of ourselves) that we also are in Him (1 Corinthians 1:30) and fellow citizens and members of His household.
Christ Jesus Himself is also the cornerstone and He is the foundation laid by the apostles.
“You also are being built together” reminds us that the building work involves us as members of Christ’s Body. “Being built” (twice) and “being fitted together” show that the building work is in progress now.
“Growing” declares that the temple in the Lord is a living building. It is composed of the living God and all who have been made alive with eternal life by receiving Jesus Christ.
We are being built together “in spirit.” This is our human spirit regenerated (John 3:6) and indwelt by the Spirit of God. It is in this mingled Spirit/spirit that we live and walk (e.g. Galatians 5:25). For more, see Living in the Mingled Spirit.
