'Service' in the Bible

So I, the prisoner for the Lord, appeal to you to live a life worthy of the calling to which you have been called [that is, to live a life that exhibits godly character, moral courage, personal integrity, and mature behavior—a life that expresses gratitude to God for your salvation],

Wives, be subject to your own husbands, as [a service] to the Lord.

Slaves, be obedient to those who are your earthly masters, with respect for authority, and with a sincere heart [seeking to please them], as [service] to Christ—

rendering service with goodwill, as to the Lord, and not [only] to men,

Now, so that you may know how I am and what I am doing, Tychicus, the beloved brother and faithful minister in the Lord, will tell you everything.
