Initially there was only God. After a while he got bored of talking to himself and created some companions, demigods called angels. Unfortunately, God is rather a bumbling creator. Hence His creation was flawed, and some of the angels decided they wanted to rule heaven themselves. There was an almighty fight, but God won and the angels, now called devils, were cast into hell.
Some time later, God got bored again and decided to create a world called Earth. On it He created plants, animals, and people, in that order. Or, depending on which Genesis story you believe, He created Adam, then the animals to keep him company and, when that was not enough, a female companion, Eve.
Not being much good at creation, God made the people flawed. The devil saw that and decided to have some fun. God, who must have noticed this, decided not to take any action, and decided to sit on the sidelines while this demigod had a go at Eve and Adam. Predictably, considering the flaws that were built-into people, and the power of their adversary, Adam & Eve failed the test.
Now God, who in his omnipotence had created a flawed design and, being omniscient, would have known what was going to happen, did not decide to fix people up properly. Instead he become enraged at them and damned not only them, but all their descendants as well. Then, to show that He could be merciful as well, He decided to give people a way out of the damnation. He did this by sending Himself, in the guise of His son, to earth, there to be crucified by the descendants of Adam. After 3 days He had enough of being cooped up in a grave, got up, said hello to his friends and returned to heaven.
On earth people were led to believe that the death and resurrection of God would fix the damnation problem they had. Unfortunately (I did say God is a bungler), that did not work very well either. Before the death of Christ, the damned people would go to heaven or hell, depending on how they lived (except, one supposes, those that God massacred in Noah's flood). After Christ, people have not changed in any way, they are still just as flawd, and they are still told that their fate after death will depend on their behaviour in life.
So here's my question: what's the point of Easter? What difference has it made to humans, in the way they live or are expected to live?
