+III. Ever rising to a higher perfection+ (ver. 21).--The image is that of an extensive pile of buildings, such as the ancient temples commonly were, in process of construction at different points over a wide area. The builders work in concert upon a common plan. The several parts of the work are adjusted to each other, and the various operations in process are so harmonised that the entire construction preserves the unity of the architect's design. Such an edifice was the apostolic Church--one but of many parts--in the diverse gifts and multiplied activities animated by one Spirit and directed towards one Divine purpose (_Findlay_). Since the Day of Pentecost, when three thousand living stones were laid on the foundation, the Church has been growing in symmetry, beauty, and vastness, and it is constantly advancing towards perfection. The building, though apparently disjoined and working in separate parts, is growing into a final unity. +IV. Made by the Spirit His glorious dwelling-place+ (ver. 22).--The Holy Spirit is the supreme Builder as He is the supreme Witness to Jesus Christ (John xv. 26, 27). The words "in the Spirit" denote not the mode of God's habitation--that is self-evident--but the agency engaged in building this new house of God. With one chief corner-stone to rest upon, and one Spirit to inspire and control them, the apostles and prophets laid their foundation, and the Church was builded together for a habitation of God. Hence its unity. But for this sovereign influence the primitive founders of Christianity, the later Church leaders, would have fallen into fatal discord (_Findlay_). The Church is a spiritual organisation, pervaded and made vital and progressive by the presence and operation of the Spirit of God. An organ is composed of several instruments--the choir, the swell, the pedal, the great; and many stops--the diapason, the flute, the trumpet; and yet it is one. And the Church of God is one. One Spirit--one breath of wind turned on by one living Hand--makes all the organ vocal. +Lessons.+--1. _The Church is the depositary of great religious privileges._ 2. _God dwells in the Church by dwelling in the heart of every member of it._ 3. _The Church provides every facility for worship and service._ _GERM NOTES ON THE VERSES._ Vers. 19-22. _The Church of God a Spiritual Building._
