In chapters 1 to 3, Paul has been laying out a great theology concerning our salvation in Christ. Now based upon this strong theology Paul starts in on hard-hitting life application.

Based upon the truth He discussed, Paul launches into how we are expected to live in response to that powerful Gospel truth. Paul is urging the Ephesians and all those reading this letter to Walk the Talk! He is saying that we need to do what we preach, never being hypocrites. 

We need to walk in a manner worthy of God’s call on our lives by pursuing unity in the body.
