1 Corinthians 7:20-23

Each one of you should stay the way you were when God called you. If you were a slave when God called you, do not let that bother you. But if you can be free, then make good use of your freedom. Those who were slaves when the Lord called them are free persons who belong to the Lord. In the same way, those who were free when they were called are now Christ’s slaves. You all were bought at a great price, so do not become slaves of people.
