Oh?
Just WHO were the others that were NOT chosen??
A&E were CREATED by GOD.
Besides; they did NOT 'reject' GOD; but did not BELIEVE God.
For many are called, but few are chosen (Matt. 22:14).
Read the wedding feast Matthew 22.
Then you may understand that many were called but they rejected Jesus. I believe that we are all called to hear the good news of the Gospel and be baptized. We can follow the path of Jesus and His Church or be led astray.
What do you call sin other than the rejection of God?
Not believing or only partially believing is the rejection of God.
