All of God's elect are born into this world, by natural birth, dead in their sins, and full of wrath, even as others, until God quickens them to a new spiritual life (Eph 2:1-5).
The elect, the chosen ones, are always those who are in Christ (Eph. 1:4). God does not determine who will be saved and who will be condemned. Actually, we do.
