It looks like you have got the whole thing backwards you must be listening to the 101 soteriology podcast. You don't read Eph.1 from verse 14Exactly so the predestination is not something that happened before the foundation of the world. When and after we believe the Gospel and then we are sealed by the Holy spirit until the day of redemption. Then we are predestined . This predestination does not happen in eternity past for individuals or groups .
Down to one and read 1 to verse 14 just exactly the opposite of what you post a look.
