Thoughts
For me, the predestination/free-will question is answered like so: humans have free-will and agency, but we don't have any power or merit.
We can screw around and make our own decisions down on Earth during our life time and some of those decisions are better than others, but there's only one decision that matters and that's allowing God save us. God takes complete responsibility for our salvation, we just let him in the door.
The distinction that I make that is very different from the distinction that Calvinists make, is that my inclination would be that even saved Christians don't have any meaningful power or merit.
The only thing that I want to keep, that I want to take into heaven, is my faith in God. When God redeems the Earth he will destroy all sinful things and if that includes everything I've ever made and every relationship I've ever had I would be okay with that. And I shouldn't be, maybe, but God won't. God will redeem many things and many relationships.
