You understand that even under Rome's framework that God must gift the cooperation needed to ultimately qualify for salvation? That even the choice to cooperate with grace must be provided by the grace of God? And that God does not provide this grace based on performance but based on His own sovereign purpose? Why does God gift some Rome Catholics enough cooperation to enter heaven while passing over others, leaving them to be (rightfully) condemned to hell? Because salvation is a work of God alone, and zero credit is owed to the creature. None.
