Note 16 at Eph. 2:21: The saints as the "household of God" (v. 19) are built upon the foundation of the teachings of the apostles and prophets. We are told that the early church "continued steadfastly in the apostle's doctrine and fellowship, and in breaking of bread, and in prayers" (Acts 2:42). Christ Himself is called the chief corner stone in which every structure is aligned perfectly on Him. This metaphor depicts believers as a carefully joined, constantly growing temple inhabited by God. The Jews and Gentiles are now an ever growing spiritual structure indwelt by God. Whereas a church building is sometimes called the house of God, in reality believers are the temple of God (1 Cor. 3:9; 6:19; see note 7 at 1 Cor. 3:16, p. 873). "For ye are the temple of the living God; as God hath said, I will dwell in them, and walk in them; and I will be their God, and they shall be my people" (2 Cor. 6:16).
