Ephesians 2:21

In whom. That is, in Jesus Christ. This expression, the key phrase of the epistle (see on ch. 1:1), expresses a mystic but real experience, as does the phrase “in the Lord” at the end of the verse. Christian growth takes place by our being “in him.”

Fitly framed together. Gr. sunarmologeo, or, “to join together fitly.” The word is translated “fitly joined together” in ch. 4:16, its only other occurrence in the NT. The church is not a pile of stones come together by accident; it has form and coherence. Each stone has its proper place. The stability of the structure depends on careful planning.

Groweth. As new members are added to the church.

An holy temple. Or, “a holy sanctuary.” As the sanctuary was peculiarly the place of God’s presence and manifestation, so the church of God is the temple in which He dwells. Everything that is touched by the hand and presence of God is hallowed, so that His sanctuary, or “holy temple,” is wherever He is.
