Ephesians 1:1-2.

According to the purpose of His will God predestined us for adoption into His family. As God’s gospel people we have new life in Christ! And then, when God’s gospel people learn how to live out this new life in Christ we live in that sweet spot where gopsel belief results in gospel behavior. This is what Paul writes about in Ephesians. He writes so God’s new community will shine as a beacon of living hope as they visibly demonstrate the work of redemption which God has done in them.
