Does'nt the concept of free will contradict gods omnipotence cos in the end he knows the choices i will make?

It is not about what God knows. It is about what we know. If we knew for sure that God exists, that hell is truly a place we could go to forever, that eternal life is incredibly wonderful and also knew we that we would make the wrong decisions all through this life, do you think you could even enjoy the few pleasures that we have now? No, it would be hell every day. All of the above are true, except for knowing our decisions. Think about it!

You have to remember that there's no proof that God knows the future.

God may not know the future.

And just because you know the future has nothing to do with free will.

If I have a time machine and can travel into the future and return, I can know what's going to happen, but that does not change anything. We all still are free to do whatever we want.

Of course! But how else is the Church going to make sure you behave if you dont know you are being watched 24/7......A person is so much easier to control if they think they are being constantly watched by their ultimate Judge.

Wow eat the whole "forbidden tree." Where did you get that from?

Humans know they do foolish things but still do them anyway.

Shhh, you aren't allowed to ask questions.

you have a point there
