Those who are "born in sins" can still become a believer. The inclusiveness of the Gospel frightens me sometimes, yet I see other religions as inclusive with a different message.
Jesus seemed to never be where His persecutors wanted Him to be until the Cross. I do not know if this was natural (running) or supernatural.
Paul, as a Jew, makes a convincing argument late in our Romans passage about the Jews and their not being rejected. That is true, even if they are immediately blinded until later.
