Just joking! But it's to make this point: I don't think either evangelism or worship necessarily qualifies as the number one reason for being for the church, and therefore for the Assemblies of God. I think the central reason for being is as this age's chief manifestation of the "Immanuel" principle, the promise of "God with us."
It seems like the core Scriptural promise is this: "I will live among you, and I will not despise you. I will walk among you, I will be your God, and you will be my people" (Lev 26:11-12, also Exod 29:45). In the Old Testament this was first manifested in divine fellowship with humanity in the Garden, but sin interrupted that. After that, a few walked with God, such as Enoch, Noah, and Abraham (Gen 5:24; 6:9; 48:15). But it was really with the building of the wilderness tabernacle and then the temple in Jerusalem that humanity might once again experience the Immanuel principle, "I will live among you" (Exod 40:34-38; 1 Kings 8:10-11; 2 Chron 7:1-3).
Even in the Old Testament, Isreal knew that the earth couldn't contain the LORD (1 Kings 8:27; Ps 11:4, cf. Acts 7:49-50). Indeed, the prophets promised a greater temple (Hag 2:7-9; Ezek 36:26-28; Zech 14). And Isaiah promised a child named "Immanuel" (Isa 7:14). When Jesus came as the incarnate Logos, God was "tabernacling" among his people (John 1:14); indeed, he is the one in whom the fullness of God dwelt bodily (Col 1:19; 2:9).
In turn, Jesus promised an extension of the Immanuel principle when he promised a new temple to replace the one that Roman crucifixion destroyed (John 2:19ff). This made the stone temple obsolete (Luke 23:34; Acts 7:49-50; Heb 9). It had been only a shadow of the true heavenly temple that followed the resurrection. Eternally replacing the former shadowing human-made temple, the Body of Christ fulfilled all the promise that God lives with his people. Indeed, individual believers are God's temple (1 Cor 6:15-20; Eph 2:21-22) and the corporate body is the temple (1 Cor 3:16-17; 1 Pet 2:5). The church exists as the fulfillment of the Immanuel principle.
Of course, we still live in the tension between New Testament fulfillment in Christ's finished work and final consummation in the eschaton. John's visions promise further fulfillment (Rev 11:19; 15:5, 8; 21:3). So the New Jerusalem has no temple building, because the Lord God Almighty himself and the Lamb are the temple (Rev 21:22; cf. 1 Kings 8:27; 2 Chron 2:6; 6:8; Isa 66:1).
God dwelling with his people is the whole point--it never was about stone and timber, any more than atonement was about the blood of bulls and goats being offered by faulty priests.
So, we the Church exists as God's temple, as the end times manifestation of the Immanuel principle. That's our most basic and over-riding reason for being. And in that temple, worship rises to God, and from that temple, works of mercy should flow, and from that temple should issue the clarion call of evangelism.
DISCUSSION STARTER:
What does this line of thought imply for the all-too common hope that there will somehow again by a stone and timber temple made with human hands?
