'Servants' in the Bible

And having been set free from sin, you have become the slaves of righteousness [of conformity to God’s will and purpose].

I am speaking in [familiar] human terms because of your natural limitations [your spiritual immaturity]. For just as you presented your bodily members as slaves to impurity and to [moral] lawlessness, leading to further lawlessness, so now offer your members [your abilities, your talents] as slaves to righteousness, leading to sanctification [that is, being set apart for God’s purpose].

For this same reason you pay taxes, for civil authorities are God’s servants, devoting themselves to governance.
