The church of God below is one with the church of God above. Believers on the earth and the beings in heaven who have never fallen constitute one church. Every heavenly intelligence is interested in the assemblies of the saints who on earth meet to worship God. In the inner court of heaven they listen to the testimony of the witnesses for Christ in the outer court on earth, and the praise and thanksgiving from the worshipers below is taken up in the heavenly anthem, and praise and rejoicing sound through the heavenly courts because Christ has not died in vain for the fallen sons of Adam. While angels drink from the fountainhead, the saints on earth drink of the pure streams flowing from the throne, the streams that make glad the city of our God. CCh 240.5
Oh, that we could all realize the nearness of heaven to earth! When the earthborn children know it not, they have angels of light as their companions. A silent witness guards every soul that lives, seeking to draw that soul to Christ. As long as there is hope, until men resist the Holy Spirit to their eternal ruin, they are guarded by heavenly intelligences. Let us all bear in mind that in every assembly of the saints below are angels of God, listening to the testimonies, songs, and prayers. Let us remember that our praises are supplemented by the choirs of the angelic host above. CCh 241.1
Then as you meet from Sabbath to Sabbath, sing praises to Him who has called you out of darkness into His marvelous light. “Unto Him that loved us, and washed us from our sins in His own blood” let the heart's adoration be given. Let the love of Christ be the burden of the speaker's utterance. Let it be expressed in simple language in every song of praise. Let the inspiration of the Spirit of God dictate your prayers. As the word of life is spoken, let your heartfelt response testify that you receive the message as from heaven. CCh 241.2
God teaches that we should assemble in His house to cultivate the attributes of perfect love. This will fit the dwellers of earth for the mansions that Christ has gone to prepare for all who love Him. There they will assemble in the sanctuary from Sabbath to Sabbath, from one new moon to another, to unite in loftiest strains of song, in praise and thanksgiving to Him who sits upon the throne, and to the Lamb for ever and ever.430Testimonies for the Church 6:366-368 CCh 241.3
