1Pe 1:2 Elect according to the foreknowledge of God the Father, through sanctification of the Spirit, unto obedience and sprinkling of the blood of Jesus Christ: Grace unto you, and peace, be multiplied.

Election and predestination are based upon the foreknowledge of Elohim.

He knows those that are His from the very beginning.

Everyone has free will, and some will accept and some will refuse the GIFT of Elohim. The point is, YHVH knew way ahead of time.
