God's Family Purpose.
The purpose of the community of the redeemed is given to Paul in Eph. 3:8-12; Unto me, who am less than the least of all saints, is this grace given, that I should preach among the Gentiles the unsearchable riches of Christ; And to make all men see what is the fellowship of the mystery, which from the beginning of the world hath been hid in God, who created all things by Jesus Christ: To the intent that now unto the principalities and powers in heavenly places might be known by the church the manifold wisdom of God, According to the eternal purpose which he purposed in Christ Jesus our Lord: In whom we have boldness and access with confidence by the faith of him.
It is God's family, that is living proof of God's gracious provision in Christ, not institutionalism. This provision contains His plan for the community of the redeemed to live His life vicariously in the community of humanity for the purpose of their becoming a part of His redeemed community.
For people to think that "church buildings" and the Sunday event-driven-meetings that take place in them, is the community of the redeemed living life while demonstrating the wisdom and power of God in the kingdom of humanity, is a mistake in location and identity.
