HOW were they predestined?
To be conformed to the image of the Son.
The PERSON wasn't predestined...
The predestinating was to make that person into the image of His Son.
So that Jesus, being the first-born, would have many brothers.
And yes, God foreknew who would come to believe in Him...
He foreknew WHO would be saved....
but God did not CHOOSE who would be saved...
only
HOW and for PURPOSE.
You concentrate on the words HE CHOSE.....
But no...
God chose us IN HIM bebore the foundation of the world......
that we should be holy.
We are In Christ at salvation.
We are saved by Christ
We are IN HIM.
God predestined His elect....those that believe and obey him.
He predestined us FOR ADOPTION....you concentrate on the words HE PREDESTINED US.
According to the purpose of His will.
The purpose of His will is to adopt us as sons THROUGH JESUS CHRIST...
This was God's plan all along...beginning in Genesis 3.15.
In Christ we have our inheritance.
God predestined for us a future in Jesus.
See Ephesians 1:13
13In Him, you also, after listening to the message of truth, the gospel of your salvation—having also believed,,,
Paul is teaching the same as in Romans....
1. We listen to the message.
2. We believe.
We listen...we believe.
No predestination.
Romans 1:16-17
16For I am not ashamed of the gospel, for it is the power of God for salvation to everyone who believes, to the Jew first and also to the Greek.
17For in it the righteousness of God is revealed from faith to faith; as it is written, “BUT THE RIGHTEOUS man SHALL LIVE BY FAITH.”
Paul teaches how to be saved:
Romans 1:6-8
6who WILL RENDER TO EACH PERSON ACCORDING TO HIS DEEDS:
7to those who by perseverance in doing good seek for glory and honor and immortality, eternal life;
8but to those who are selfishly ambitious and do not obey the truth, but obey unrighteousness, wrath and indignation.
The context does not include God predestinating, from before time, WHO will be saved and who will be lost.
Acts 16:31 What must I do to be saved?
31and they said, Believe in the Lord Jesus and you shall be saved.
