God is familiar with those, "fore-knowing" whom He intends to redeem to Himself because God created them for His purpose, not because God reviewed their actions and determined them worthy.
None of Man's actions are worthy of God, and no man is able to come to Christ without God first transforming them.
Therefor, God foreknew them in intimate familiarity because they belong to Him, not because God likes who they became in themselves, but because God has a purpose unto Himself.
