Ephesians 3 v 1 - 13 - Open Secret

Ephesians 3v1-13
The big picture is that God's mystery is being revealed and we will be united as one church as equals. Paul is revealing God's administrative plan for the church that Paul knows through divine revelation. There's a continuity from the day before's verse, repeating the word together emphasising that Jews and Gentiles really are united now and this unity hadn't previously existed. The eternal purpose is to create a church where people are united under the headship of Christ. 
Paul is under house arrest here because he spoke out about Christ, and even he thinks he is unworthy. We're lucky to live in a country where there is opposition, but not much persecution, but yet how much do we talk about Christ and speak out?
