See my 186 post. The odds of you choosing Tahiti are X, the odds of what you eat based on what you like are X, the odds of how you shop for gas are based on X. You DNA code directs 1/2 of your behavior at conception. The rest is the variables (weather, people, animals etc.) which we cannot control. But that is what freewill means, at least with people. The perspective from God’s point of view is that you had a 99% chance of going to Tahiti, eating fluffernutters and using a car on your travel. It is still my decision to buck the variables (predictions) and I could choose to go to Mexico, eat nachos and stare at the sunset from a boat.
There is no such thing as “chance”. To suggest otherwise is to deny God’s soveriegnty.
