'Slaves of God' in the Bible

“No one can be a slave of two masters, since either he will hate one and love the other, or be devoted to one and despise the other. You cannot be slaves of God and of money.

But now since you have been set free from sin and have become [willing] slaves to God, you have your benefit, resulting in sanctification [being made holy and set apart for God’s purpose], and the outcome [of this] is eternal life.

[Live] as free [persons], and not using your freedom as a covering for evil, but as slaves of God.
