Romans 2:28-29 New Life Version (NLV)
28 A man is not a Jew just because he goes through the religious act of becoming a Jew. 29 The true Jew is one whose heart is right with God. The religious act of becoming a Jew must be done in the heart. That is the work of the Holy Spirit. The Law does not do that kind of work. The true Jew gets his thanks from God, not from men.
