What?
Only those drawn are saved (ie: adopted to be sons of god) and those who are adopted are predestined to be.
Being saved is Not equated with being adopted. In fact, Scripture is very clear that ONLY believers are adopted.
John 1:12
But as many as received Him, to them He gave the right to become children of God, even to those who believe in His name,
Seriously, lose the jargon and just read the book.
Sure, let's be serious. Here's what Eph 1:5 actually SAYS:
Ephesians 1:5
He predestined us to be adopted as his sons through Jesus Christ, in accordance with his pleasure and will
Again, note who He predestined: "us". Defined in 1:19 as BELIEVERS. Why won't you deal with that fact?
Next, note what believers are predestined to be: adopted as His sons. I'll repeat: believers are adopted as sons.
Finally, we read about the means of this adoption, which is "through Jesus Christ". This simply cements the FACT that God adopts ONLY believers to be His sons.
Because one becomes a believer ONLY "through Jesus Christ".
I've repeatedly exegeted these verses, compared to your eisegesis of the verses.
So, I don't need to lose any "jargon", since I've directly dealt with the text and what is SAYS. I suggest losing your eisegetical approach to the verses.
