I realize many people like to believe they are in control of their future. But, to me at least, it seems much, if not all of life, is a gamble.
Hi .. I don't think we can say it is "a gamble".
Quite obviously, there are a lot of things that we have no control over, as an individual, such as so-called "acts of God".
However, some of these "acts of God", such as floods and earthquakes, are happening due to something that we, collectively, are really responsible for.
i.e. climate-change
..so it is not just about our individual choices, but is about the choices we make as a community .. as a nation ... ...
"free-will" as given to us by God, refers to the individual choices that ARE in our control.
The decisions that we make every day, which affect us physically and spiritually.
Yes, our future is known by Almighty God, as He does not "live" in His created universe [ space-time continuum ].
Our free-will is not affected by the future being known by God .. the future is shaped by our choices.
..it is that God knows what we will choose.
