b. revealed to us

Key Scripture (Ephesians 3:5-6): which was not made known to people in other generations as it has now been revealed by the Spirit to God’s holy apostles and prophets. This mystery is that through the gospel the Gentiles are heirs together with Israel, members together of one body, and sharers together in the promise in Christ Jesus.

Key Scripture (Ephesians 3:7-10): I became a servant of this gospel by the gift of God’s grace given me through the working of his power. Although I am less than the least of all the Lord’s people, this grace was given me: to preach to the Gentiles the boundless riches of Christ, and to make plain to everyone the administration of this mystery, which for ages past was kept hidden in God, who created all things. 10 His intent was that now, through the church, the manifold wisdom of God should be made known to the rulers and authorities in the heavenly realms,

b. Requests made

Key Scripture (Ephesians 3:16-19):  I pray that out of his glorious riches he may strengthen you with power through his Spirit in your inner being, 17 so that Christ may dwell in your hearts through faith. And I pray that you, being rooted and established in love, 18 may have power, together with all the Lord’s holy people, to grasp how wide and long and high and deep is the love of Christ, 19 and to know this love that surpasses knowledge—that you may be filled to the measure of all the fullness of God.
