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. (Ephesians 3:8–12, NKJV)
The gospel Paul preached reveals the “unsearchable riches of Christ” for all the world to see. In it, salvation from sin is available to all “by grace…through faith” (v. 8; Eph. 2:8). The gospel Paul preached reveals God’s purposes for the redemption of sinners in Christ (v. 9). The gospel Paul preached reveals the importance of the church (v. 10-11). First, because “by the church,” God’s many-sided wisdom is made known to the unseen realms (v. 10; 1 Pet. 1:10-12). Second, because it is crucial to God’s “eternal purpose” fulfilled in Christ (v. 11). The church is not an afterthought of God. The gospel Paul preached reveals our bold and confident access through faith in Christ into every spiritual blessing of God (v. 12, Eph. 1:3). The gospel is truly the wisdom and power of God (1 Cor. 1:24). The church (the redeemed) is the product of the gospel (Acts 2:47). The church is important to God. It must be important to us.
