Elbib» Fall is not a one-time event nor a universal event. It happens with many, and it does not happen with many. Feeling more important than others is the fall and this is the root cause of all problems. If one refuses to feel more important than others, he would remain as firm as a mountain against fall. And refusal to feel more important than others is very much possible "if one wants to" even now.
Fine, but you're approaching a very complex topic very superficially. According to Christian theology, if you're subject to death, you're burdened by the fall (as are we all). So if we're to discuss it, we must first define our terms. I don't feel more important than others, nor do many people I know. We try to use Jesus as our guide, and he, in the view of most Christians, was Yahweh in premortality. Yet he never snubbed anyone. He operated under the saying he gave his followers, namely, that the greatest of all is the servant of all. One of my favorite New Testament stories is the one of Jesus and the woman at the well. It was, as far as we know, the first announcement by Jesus of his identity as the Messiah.
The law given by God to Israel was very detailed and doesn't at all smack of self importance on God's part at all. Because the people had rejected God, even refusing to see him in his glory, and because they returned to the gods of the Egyptians, the law became a curriculum for a more primitive people; however, it directed people to love each other, to care for their animals and the poor. There were no other gods or theologies before or after, East or West, North or South, that were as compassionate, thoughtful or beneficial to the people than the God of Israel. The gods created by men either served men's lusts or greed or they were only distantly associated with their creations. The God of Israel sought to make people better; to make them conscious of the needs of other. It wasn't perfect, because the people weren't perfect, but it shouldn't be underappreciated. It was never based on the self importance of God but on lifting people up, making them more better and ultimately bringing them back into his presence.
