2:19-22 The church is compared to a city, and every converted sinner is free of it. It is also compared to a house, and every converted sinner is one of the family; a servant, and a child in God's house. The church is also compared to a building, founded on the doctrine of Christ; delivered by the prophets of the Old Testament, and the apostles of the New. God dwells in all believers now; they become the temple of God through the working of the blessed Spirit. Let us then ask if our hopes are fixed on Christ, according to the doctrine of his word? Have we devoted ourselves as holy temples to God through him? Are we habitations of God by the Spirit, are we spiritually-minded, and do we bring forth the fruits of the Spirit? Let us take heed not to grieve the holy Comforter. Let us desire his gracious presence, and his influences upon our hearts. Let us seek to discharge the duties allotted to us, to the glory of God.

groweth—"is growing" continually. Here an additional thought is added to the image; the Church has the growth of a living organism, not the mere increase of a building. Compare 1Pe 2:5; "lively stones … built up a spiritual house." Compare Eph 4:16; Zec 6:12, "The Branch shall build the temple of the Lord," where similarly the growth of a branch, and the building of a temple, are joined.
holy—as being the "habitation of God" (Eph 2:22). So "in the Lord" (Christ) answers to "through the Spirit" (Eph 2:22; compare Eph 3:16, 17). "Christ is the inclusive Head of all the building, the element in which it has its being and now its growth" [Alford].
