For free will to exist, we must belive in a non-deterministic point of view of reality, in which the universe is not predictable nor chaoticly random, but somehow choices can be made. If God gives us weakness, free will and dosen't let us know of what is going on and the porpouse of our lifes, and dosen't let himself know of his holy existance, then why does God punish man for doing what is wrong?
The child, learning how to ride a bike, KNOWS she is on the bike to learn it. The parents didn't just bought a bike and had the child seat on it and told her nothing, being completely absent.
Of course, one could say that God cannot let menkind know of such divine existance because that would interfere on people's judgment, but if there is no point in the lesson given, is there a point in the teaching of the lesson?
It's all too complicated, and I've given up finding an answer and decided to let the experts handle this. I will live my life the best way I can, not doing harm to other people, and when I die, I'll expect nothingness. If anything else happens, oh well, surprise.
