When it comes to the book of Ephesians, we can quickly, and often errantly, jump to the commands of chapters 4-6 without first being informed, equipped, challenged, and comforted with the works of Christ on our behalf that enable us to rise in obedience to the commands of chapters 4-6.

It is perfectly obvious that not everyone submits to everyone else, and it is foolish to imagine it so. Elders do not submit themselves to parishioners, police do not submit themselves to citizens, and husbands do not submit themselves to wives. What Paul is indicating here is that, although not all people submit to each other, all people do submit to someone.
