He doesn't need to because he sees every instance every outcome every situation and his understanding of eternity is far beyond oursCan God choose not to know the outcome of every event?
He doesn't understand time or the out come of things like we do we will never be able to comprehend his way of doing things. think of this say that there is a person before God and God is showing them every outcome for every choice they ever made or didn't make thousands of different outcomes would be shown if not millions because every choice we do or don't make has a different outcome and then that outcome is also based on the choices others made as well it is like a ripple effect
God sees and knows all period and we never know or understand the small choices we make or don't make and how far they go. this is why we must consider how eternity works because with our human understanding we see only what our limited view can but he sees and knows all
