According to Ephesians 1:5 we are adopted by God the son/Jesus Christ unto himself. Is God the Son the same Person as God the Father?
God the Son/Jesus adopts us mortals into his family. You cannot be predestinated, unless you preexisted.
Since God the Father is the Father of our spirits (Romans 8:16, Numbers 27:16,
Hebrews 12:9) we preexisted.
Therefore, we were predestined to come to earth and be adopted by God the Son/Jesus Christ unto himself, and we become his sons and daughters too.
It all fits.
No, you should know that the subject of the sentence is the Father.
Eph. 1 KJV
3 Blessed
be the God and Father of our Lord Jesus Christ, who hath blessed us with all spiritual blessings in heavenly
places in Christ:
4 According as he hath chosen us in him before the foundation of the world, that we should be holy and without blame before him in love:
5 Having predestinated us unto the adoption of children by Jesus Christ to himself, according to the good pleasure of his will,
6 To 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;
8 Wherein he hath abounded toward us in all wisdom and prudence;
9 Having made known unto us the mystery of his will, according to his good pleasure which he hath purposed in himself:
10 That in the dispensation of the fulness of times he might gather together in one all things in Christ, both which are in heaven, and which are on earth;
even in him:
11 In whom also we have obtained an inheritance, being predestinated according to the purpose of him who worketh all things after the counsel of his own will:
12 That we should be to the praise of his glory, who first trusted in Christ.
13 In whom ye also
trusted, after that ye heard the word of truth, the gospel of your salvation: in whom also after that ye believed, ye were sealed with that holy Spirit of promise,
14 Which is the earnest of our inheritance until the redemption of the purchased possession, unto the praise of his glory.
Ephesians 1 ESV
3 Praise be to the God and Father of our Lord Jesus Christ, who has blessed us in the heavenly realms with every spiritual blessing in Christ.
4 For he chose us in him before the creation of the world to be holy and blameless in his sight. In love
5 [the Father]he predestined us for adoption to sonship through Jesus Christ, in accordance with his pleasure and will—
6 to the praise of his glorious grace, which [the Father]
he has freely given us in the One he loves. (the one he loves is his beloved Son)
7 In him we have redemption through his blood, the forgiveness of sins, in accordance with the riches of God’s grace
8 that he lavished on us. With all wisdom and understanding,
9 [the Father]
he made known to us the mystery of his will according to his good pleasure, which [the Father]
he purposed in Christ,
10 to be put into effect when the times reach their fulfillment—to bring unity to all things in heaven and on earth under Christ.
Romans 8
… you have received the Spirit of adoption as sons, by whom we cry, “Abba! Father!” The Spirit himself bears witness with our spirit that we are children of God,
You non-trinitarians don't get it.
