The money (or heaven) is already in the box. Omega (or God) can not change the outcome.
What makes this kind of reasoning work in the real (natural) world is the growth of entropy involved in putting money in boxes, deciding to do so, or thinking about whether the money is there. If we’re taking theology seriously though—or maybe even when we posit an “Omega” with magical sounding powers—we need to wonder whether the usual rules still apply.
When dealing with theology, you need to be careful about invoking common sense. According to https://www.thegospelcoalition.org/themelios/article/tensions-in-calvins-idea-of-predestination/ , Calvin held that God’s destiny for a human being is decided eternally, not within time and prior to that person’s prayer, hard work, etc.
