See EGW comment on Revelation 19:7-9.

 Christ “loved the church, and gave himself for it.” It is the purchase of His blood. The divine Son of God is seen walking amid the seven golden candlesticks. Jesus Himself supplies the oil to these burning lamps. He it is that kindles the flame. “In him was life; and the life was the light of men.”
 No candlestick, no church, shines of itself. From Christ emanates all its light. The church in heaven today is only the complement of the church on earth; but it is higher, grander—perfect. The same divine illumination is to continue through eternal ages. The Lord God Almighty and the Lamb are the light thereof. No church can have light if it fails to diffuse the glory it receives from the throne of God (Manuscript 1a, 1890).

 The church of Christ is very precious in His sight. It is the case which contains His jewels, the fold which encloses His flock (Manuscript 115, 1899).
