Therefore, remember that at one time you Gentiles by birth, who are called “Uncircumcision” by those who called themselves “Circumcision,” [itself a mere mark] which is made in the flesh by human hands—

and [that you may come] to know [practically, through personal experience] the love of Christ which far surpasses [mere] knowledge [without experience], that you may be filled up [throughout your being] to all the fullness of God [so that you may have the richest experience of God’s presence in your lives, completely filled and flooded with God Himself].

You are therefore no longer mere foreigners or persons excluded from civil rights. On the contrary you share citizenship with God's people and are members of His family.

For ours is not a conflict with mere flesh and blood, but with the despotisms, the empires, the forces that control and govern this dark world--the spiritual hosts of evil arrayed against us in the heavenly warfare.

not with mere external service, as though you had only men to please, but like slaves of Christ, carrying out the will of God.
