Paul declares in First Corinthians 9:19-23, “Though I am free and belong to no one, I have made myself a slave to everyone, to win as many as possible. 20 To the Jews I became like a Jew, to win the Jews. To those under the law I became like one under the law (though I myself am not under the law), so as to win those under the law. 21 To those not having the law I became like one not having the law (though I am not free from God’s law but am under Christ’s law), so as to win those not having the law. 22 To the weak I became weak, to win the weak. I have become all things to all people so that by all possible means I might save some. 23 I do all this for the sake of the gospel, that I may share in its blessings.”

It is radical to imagine that a Jew would have to become a Jew to Jewish people.  You need to take a moment to take that in.  It demonstrates how Paul did not allow the gospel to be enslaved by culture.  He did not allow his own background and upbringing to be synonymous with the gospel.  The gospel is to transform culture not be defined by it.  Today we often allow our culture to define how we practice our faith.  We should study and comprehend our faith and let it transform the society in which we live.
