The lifeguard who prevents me from swimming where there is a dangerous rip tide save my life every bit as much as the lifeguard who paddles out on a surf board to rescue me from that rip tide. Mary was saved by Jesus when she was preserved from sin. Mary was saved because of Her complete and unconditional faith and cooperation, not by it.
Peace be with you
If she was compelled from without it wasn’t faith and cooperation, Natural Law. It was predestination on an individual level.
