In Ephesians 1 We have been Chosen in Him for what ( that's the question to ask ) ? to be Holy and blameless ect.
All those that have believed the Gospel FOR ?
that we should be holy and without blame before him in love:
5Having predestinated us unto the adoption of children by Jesus Christ to himself, according to the good pleasure of his will,
6To the praise of the glory of his grace, wherein he hath made us accepted in the beloved.
7¶In whom we have redemption through his blood, the forgiveness of sins, according to the riches of his grace;
Ok According to Ephesians 1.5 what are we predestined to ? to the Adoption . When is the Adoption ? this is the error most folks make . They think this Adoption is when we first are saved . But read Roman's 8 .23 and ask when is the adoption?
23And not only
they, but ourselves also, which have the firstfruits of the Spirit, even we ourselves groan within ourselves, waiting for the adoption,
to wit, the redemption of our body.
So ephesians 1 is not about being Gnostically hand picked before we are even born , to be saved later by being zapped awake ( frozen chosen ) . The predestination here is believers after they are saved ( in real time ) are guaranteed future Adoption. But this is not granted to lost uncreated people before they are born in a mysterious secret gnostic unconditional election in the mind of God but a blessing given to those who are alive who believed the truth so as to be saved.
