Scripture to Meditate On: Ephesians 3:1-13
For this reason I, Paul, a prisoner for Christ Jesus on behalf of you Gentiles—assuming that you have heard of the stewardship of God's grace that was given to me for you, how the mystery was made known to me by revelation, as I have written briefly. When you read this, you can perceive my insight into the mystery of Christ, which was not made known to the sons of men in other generations as it has now been revealed to his holy apostles and prophets by the Spirit. This mystery is that the Gentiles are fellow heirs, members of the same body, and partakers of the promise in Christ Jesus through the gospel.

Of this gospel I was made a minister according to the gift of God's grace, which was given me by the working of his power. To me, though I am the very least of all the saints, this grace was given, to preach to the Gentiles the unsearchable riches of Christ, and to bring to light for everyone what is the plan of the mystery hidden for ages in God who created all things, so that through the church the manifold wisdom of God might now be made known to the rulers and authorities in the heavenly places. This was according to the eternal purpose that he has realized in Christ Jesus our Lord, in whom we have boldness and access with confidence through our faith in him. So I ask you not to lose heart over what I am suffering for you, which is your glory.

Thoughts to Ponder:
Regarding Ecclesiology...
The church is the community of all true believers for all time. This definition understands the church to be made of all those who are truly saved. Paul says, "Christ loved the church and gave himself up for her" (Eph 2:25). Here the term "the church" is used to apply to all those whom Christ died to redeem, all those who are saved by the death of Christ. But that must include all true believers for all time, both believers in the New Testament age and believers in the Old Testament age as well. ~Wayne Grudem

The starting point in ecclesiology is the ontological connection between Christ and the church. The church exists as church only insofar as it is Christ’s body, in union with him, meaning also our union in him, both of which are a matter of his free and gracious choice. The church has no other ground of being than Jesus Christ. This means in a primary way that the church is not the church as institution, or a voluntary collection of free, religiously and ethically motivated individuals, or, with its episcopate, as an historically ordered hierarchy that determines what it is and what it does. It is Christ alone who determines the “that” and the “what” of the church, who loves the church and calls and forms it according to his own purpose. The church is what he is in that he is Lord of the church in whom and from whom alone it has life. As such, the church belongs to Christ, not to itself. The church is not self-referenced. In a primary sense, its being is iconic, not institutional, as it points away from itself to Christ. ~Andrew Purves Reconstructing Pastoral Theology (pg. 97)

[T]he church in Scripture is composed of all the redeemed in every age who are saved by grace through personal faith in the sacrificial work of Jesus Christ, “the seed of the woman” (Gen. 3:15) and suffering Messiah (Isa. 53:5–10). ~Robert L. Reymond A New Systematic Theology of the Christian Faith (pg. 805)
