As Ephesians comes to a close, Paul brings us as Christians to the realization that in all of these things that he's spoken about we are in a spiritual battle.
Paul addresses himself to slaves and masters but if what he says is true for slaves and masters how much more so for us who are freely contracted to work.
Spirit-filled people are thankful always and for everything. Such people submit to one another out of reverence for Christ.
Paul's command to be filled with the Spirit means to continually abide and to walk under the influence of the Spirit's power and authority.
To preserve the quality of our conversation, we're to fill our talk with thanksgiving. This raises the bar and keeps us from immoral conversation.
Paul's metric of church growth is Christ himself. We are to grow up into the fullness of Christ by walking with and wearing Christ. These are metaphors for repentance.
God is uniting all things in heaven and on earth through the church and making a new humanity composed of Jews and Gentiles united.
