Eph 1.5 . Paul is telling already saved believers in Christ that along with all the blessings that come in christ , is also that they are predestined to the adoption . This is not Paul telling those in christ that they were predestined to be converted . But rather to the Adoption ,WHICH HAS NOT HAPPENED YET .
Likewise in Romans . Even inspite of a tenuous connection to " oh were gradually being conformed to the image of christ day ,by day ,a little like Jesus every day " ..No the ' being conformed to his image is also referring to a future occurance . The Adoption. The blessed hope . whilst those who think they have been elected to be saved are spending their lives wondering if they are ( by their works ,) Those that understand the bible saying that Election is to service and purpose . Predestination is to the future Adoption have scripture for this ,and are resting on the promises of predestination being the Guranteed future glorification.
But where does it say predestination is after conversion
To say that...
A. because what we are predestined to is largely yet future,
B. that it necessarily follows that God’s act of predestining us follows/comes after our faith
is a grand non-sequitur
Here is your argument
A. Paul is writing to people already saved
B. He is telling them that they are predestined to something that is future
C. Therefore they were not predestined until they believed.
A and b are correct,but c does not necessarily follow from them. It is a non sequiturs argument.
It looks at the doctrine of predestination SOLELY from man’s side, and doesn’t say anything about when God predestinated them.
There is nothing in a and b that answers the question of when.
Suppose I intended to adopt a infant son and give all my wealth to him when He grew up. This purpose of mine did not necessarily pop into my mind after I adopted him. I first intended to adopt him and then I had to actively adopt him. And I may have purposed the whole thing before I adopted him.
The plan and intention existed before the actions
Seeing that God knows all things, He knows who He will adopt before they are saved
And seeing that He is not so imperfect in knowledge that things must happen before He can know them, He always knew. Otherwise, you have God learning and increasing in knowledge.
Your view of God is of a God who is wholly dependent on man.
