“Jesus didn’t choose him TO fail.
Jesus chose him knowing what he would do.”
Which was fail. He failed because he was chosen to fail. If he hadn’t been chosen, he would not have failed.
That’s why it is a self-fulfilling prophesy. It is speculation.
The text says “He was chosen and then he failed”. It just says, at some point, Jesus was aware Judas was going to fall. It doesn’t say when but we are made aware of it at the Last Supper.
God hardened Pharoah’s heart.
Because Pharoah chose to have a hard heart.
We think in human terms and think God does, too - but God says:
"These things you have done, and I kept silent; You thought that I was altogether like you..." (Psalm 50:21a)
But He is not like us.
He is God - there is no other.
Jesus chose Judas, knowing he would betray Him.
He had already failed.
Jesus didn’t set him up to fail and I suspect that if Judas had repented as Peter did, that Jesus would have welcomed him back.
