All that quote means is that God has knowledge of the future, or the ability to manipulate it to his desired outcome. At most, I believe it too mean Heaven(the phase) is outside "time" due to being a separate dimension from the universe. But when Gabriel fell into the universe they obviously became beholden to time. Basically, Gabriels home is acausual not Gabriel themself. Not sure how it applies to Accel either. Cause Accel ain't a phase being lol, Sure he's technically a angel now. But he isn't a Christian angel like Gabriel. But a thelemic angel who are explicitly not a part of the Christian phase. And like he lives in the universe, within time
