'Enslaved' in the Bible

For we know that our old self was crucified with Him in order that sin’s dominion over the body may be abolished, so that we may no longer be enslaved to sin,

and having been liberated from sin, you became enslaved to righteousness.

But now, since you have been liberated from sin and have become enslaved to God, you have your fruit, which results in sanctification—and the end is eternal life!
