Your reading that word in where it’s not stated in Romans 9. Predestination has to do with the already saved believer. Predestination has nothing to do with the lost. I am predestined for the future adoption because I’m in Christ. I’m in Christ because I believed the gospel of Jesus Christ. That is my destination now that I’m in Christ. It hasn’t happened yet.
Explain away this from Isaiah. I prefer what the Bible says says instead of man.
Isaiah 46:8 to 10 NIV
8 “Remember this, keep it in mind,
take it to heart, you rebels.
9 Remember the former things, those of long ago;
I am God, and there is no other;
I am God, and there is none like me.
10 I make known the end from the beginning,
from ancient times, what is still to come.
I say, ‘My purpose will stand,
and I will do all that I please.’
