What might be the grammatically indicated substantive being modified or described by the "nominative singular neuter" adjective "all." The spiritual mindedness of the ones loving God!! What aspect of that "spiritual mindedness?" Their trust and devotion for God!!!
Romans 8:28 (Interpretive translation)
"And we see that to the ones loving God, all
their trust and devotion is working together for good, for the ones being called according to His purpose."
Here "their trust and devotion" has been added to clarify the scope of the word "all" in the verse.
The concept that sin accomplishes good is a fiction and a destructive heresy in my opinion. Paul would say, "God forbid."
Clearly when we ask the question, "to what are "all these" referring?" The answer is to the aspects of their love of God. And those are trust and devotion. And what good is said to come from these? They are being called into God's kingdom according to God's purpose!!!
Thus once again traditional but ambiguous translation allows speculators to manufacture false doctrine.
This view meshes with
James 2:5 which teaches God chooses those who love God
James 2:5 (Interpretive translation)
Listen, my beloved
siblings in Christ, did God not choose the poor to this world
yet rich in faith and heirs of the kingdom which He promised to
those who love Him?
