If God has created the Universe and everything in it, this means that God has also created every choice that a person makes, every action a person performs.
If God has created the Universe and everything in it, this means that everything that happens is up to God.
If God is transcendant and controlling. If God is immanent or also immanent and we are a part of God, then perhaps it is not like that.
Tell me more.
I think that once a First Cause is postulated, everything eventually boils down to it.
Some people argue that this isn't so, and postulate a kind of a break of this causal chain at the point of creation of a person/soul - as if from that point on, God had nothing to do with his creations anymore, except on Judgment Day.
Both in Christianity and in Hinduism, I have heard of the notion that "We are God's", that God says "You are Mine". This could, of course, be interpreted in several ways. But it can also be interpreted to mean that everything is somehow connected to God, either in affection or disaffection, but definitely connected.
Just because the connection is complex, doesn't mean there isn't one or that we should do as if there weren't one.
