I believe that everything has already been determined by God to the smallest and finest detail. We get to live an adventure because we don't know how each day goes until it is over. But the future is just as set in stone as the past, and this should be a comfort to you.
We live in the relative, we rest in the absolute.
Proverbs 16:9
A man’s heart plans his course, but the LORD determines his steps.
Isaiah 46:9-11
Remember the former things of old; for I [am] God, and there is none else; [I am] God, and there is none like me;
declaring the end from the beginning, and from ancient times the things that are not yet done, saying, My counsel shall stand, and I will do all my pleasure; calling a bird of prey from the east, the man of my counsel from a far country. Yea, I have spoken, I will also bring it to pass; I have purposed it, I will also do it.
Psalm 139:16
Your eyes saw my unformed substance; in your book were written, every one of them, the days that were formed for me, when as yet there was none of them.
There are more verses, but I think that these sum it up succinctly. This is an important realization to come to in faith because curchianity doesn't believe these as they don't believe that Christ died for sins. If God is responsible for everything then it takes away the ability to save ourselves by "making a descision for Christ" that they hold so dear. They believe that Christ died for everything except for the sin of unbelief, which it turns out is the only one that really matters. Their "0.0001%" contribution to the equation is effectively greater than Christ’s "99.9999%" because without it they believe they aren't saved despite the "99.9999%". I assert that God is 100% responsible for everything, good and evil, and that Christ’s work is 100% effective whether someone realizes that it worked or not. And I wouldn't want it any other way.

@rockfox's comment that:
"There are times when God has been surprised by peoples actions. Time's when God has regretted doing things. Times when God has had his mind changed. I don't see reality as a predetermined play where God is both playwright and actor and nothing can change."
I would say that God condescends (i.e.
with-descends) to our level to speak in temporal, relatable terms. Sometimes He chooses to speak like a mortal human to be better understood, and create a greater emotional connection. This isn't an alteration of His nature any more than when any of us talk to a baby in an entirely ridiculous manner that we would never use with another adult – we do it to connect with the baby.
The timing for all events, including those
@steve listed, are predetermined regardless of what we do or think.
There is no way we can bugger up God's plan, and that's a good thing. The beauty of it all is that we get to have that peace while still experiencing the excitement of discovering what God has written for our lives, one page at a time.
