At least I know what I believe. You,on the other hand, have no idea what you believe.
You are like a piece of paper tossed in the air that just blows about.
You do have free will. You just don't know how to use it.
Because one is not predestinated doesn't mean that they can't have a r/s with God. It just means that they have not been called to be in the first resurrection.
The second resurrection is a resurrection to judgement. It is not a resurrection to sentencing.
In the second resurrection the "books of life" are opened. Rev. 20.
Read the other two chapters of Revelations. One will clearly see that eternal life is being offered
So yes, you will have to make a choice. You will have the free will to do that.
