1 Corinthians 7:18-19
18-19Were you Jewish at the time God called you? Don't try to remove the evidence. Were you non-Jewish at the time of your call? Don't become a Jew. Being Jewish isn't the point. The really important thing is obeying God's call, following his commands.
20-22Stay where you were when God called your name. Were you a slave? Slavery is no roadblock to obeying and believing. I don't mean you're stuck and can't leave. If you have a chance at freedom, go ahead and take it. I'm simply trying to point out that under your new Master you're going to experience a marvelous freedom you would never have dreamed of. On the other hand, if you were free when Christ called you, you'll experience a delightful "enslavement to God" you would never have dreamed of.
