A question for you to contemplate: If there is “free will” now, as you define it, will there be the same “free will” in Heaven?
I can’t answer that authoritatively. I am not sure what heaven will be like, except that we will be in the presence of God. I think at that point free will is no longer an issue. For example, if God made His presence absolutely known to us today, where would faith go? Faith only exists when we cannot fully know. That’s what faith is. In heaven, faith will no longer be needed because we will be in the presence of God.
Of course there is free will in Heaven...just as there was in the Garden of Eden.
That's the way God works.
