Have only started reading, but I have a question that I hope can be answered... When did God create Gentiles? I have read the Bible several times from start to finish,and granted, the wording can be tricky ,to me, but as far as I know. He only created 2 and through them the earth became populated. Doesn't that make us all Jews?? At least to some degree?? Would love to get an answer to this please. Thank you. Blessings
