Ephesians as a Missionary Blueprint.

Ephesians 3:8  – To me, who am less than the least of all the saints, this grace was given, that I should preach among the Gentiles the unsearchable riches of Christ,  ⁹ and to make all see what is the fellowship of the mystery, which from the beginning of the ages has been hidden in God who created all things through Jesus Christ; ¹⁰ to the intent that now the manifold wisdom of God might be made known by the church to the principalities and powers in the heavenly places, ¹¹ according to the eternal purpose which He accomplished in Christ Jesus our Lord, ¹² in whom we have boldness and access with confidence through faith in Him. ¹

This economy, or household rule, is a divinely designed system for the dispensing of God’s multifaceted wisdom and for the display of that wisdom to powers and principalities in the heavenly realms (3:10). Simply put, this self-disclosure of God is the church.  That doesn’t mean the building or the structure but the gathered community of believers.  According to Paul the whole point of his missionary calling was to establish churches that would make known the “manifold wisdom of God”.
