Are We Elect Slash Chosen by God?

Are we elected slash chosen by God is our salvation all by grace or do we have to make a choice? How can that be grace? I'm very confused says Devon. Let's open up another massive can of worms then. This is of course a classic theological problem, though it actually goes back way behind Augustin and Aquinas and so on. They believe very clearly that some people were chosen by God and some people seemed not to be part of the problem.
