 Think about what you were at first. You were not Jews, so you didnt belong to the special mob called Israel. And at that time you were not friends with Jesus Christ. You didnt know that God promised to send him to save us. And before, when God promised to look after the Israel mob if they agreed to keep his law, he didnt promise that to you. You didnt know anything about those things. You were living without God, and there was nothing good for you in this world. You didnt know anything about the young man operation that God told the Jewish people to do on all their boys. Thats the reason why the Jewish people rubbish you. But dont worry about that. They are only talking about the operation that people do to their bodies. They are not talking about the job that God does inside us.
