Here's a concept; we all lived with God and have existed forever. God did not create us ex nihilo; we became His children by accepting His leadership, and He taught us.
Eventually, we learned allt hat could be learned in an environment where the truth was always in front of us. God said, OK the next step is you are going to have to leave me. We will see what you are truly made of with your own ability to discern and choose between good and evil. I will give you instructions on how to live a happy, productive, life - and if universally followed (not by coersion but by each individual's free choice) these rules will create a heaven condition on earth. To the degree that they are not followed, condtiions will worsen. To the degree that one person tries to dominate or control another thru force ore deception, this will be in opposition to the correct way. Oh and by the way, everyone is going to screw up, and since unclean thinks cannot abide my presence, I will provide a savior, who being both perfectly clean and also by taking all of the suffering associated with every sin ever committed - by those who will accept Him all may return to my presence.
Then another being said he had a better idea that would allow all to return to God's presence. We would just have to sacrifice some freedom, but all would share the same outcome (outcome based education?) - this plan should sound familiar and shows the roots of socialist ideas - they appear to be compassionate but of NECESSITY require that freedom be sacrificed. There was a pretty big argument about which plan was better, and eventually 1/3 of everybody went with the latter plan and sought to take the leadership position. They thus failed the first test, and lost the opportunity to further progress. Becoming an enemy to God, he also provided the opposition so that a choice other than God would exist.
For those that say that God cannot be both omnipotent, good, and for bad things to happen - that is just lack of understanding of God's plan, it is like with broken window theory where Bastiat talks about the seen and the unseen. Those who feel that war helps the economy, fall into this fallacy. In the eternal perspective, those who say there cannot be a God really mean "Because if I were God, and I were omnipotent, I would do things differently!" This is because they focus on the seen, but do not understand or comprehend the unseen. None of us do, fully, if we did it would be no more of a second trial than if we had remained in His presence.
Now of course, this raises countless questions, such as "What about people who never even heard of this?" What was the point of their lives? What about the horrors of mass starvation, or the millions killed by tyranny, etc?" To the latter I would say that largely, part of our test is to see what WE will do about it, not for us to complain that God does nothing about it. Much of the suffering is completely due to disobedience to the rules of happiness. That is other thing - those who consider only the seen tend to think of the rule book as coersive, loss of freedom, because if they follow the rules they can no longer "do what they want". Which is hogwash - of course there is not a single thing that I cannot do that a non-believer can. I can have all the sex I want with anyone I want - asumming I can entice them or have the physical strength to force them. What constrains me is the same thing that constrains a car owner from pouring sugar in his gas tank - the rules aren't there for the sake of restriction, they are a guide to true happiness and not the counterfeit happiness which is offered by the enemy. Certainly I would not suggest that the countereit doesn;t "feel good" even exhilerating, fun, enjoyable. Much as a diet of soda, ice cream, candy, fast food, etc. provides a pleasurable "sugar rush", and are even acceptable and good within proper bounds, there is harm when indulged in beyond the proper bounds. And while a child might prefer a meal of cotton candy, cake, ice cream, etc. an adult properly enjoys a good steak, salad, and also knows the long term benefit of eating properly.
No ill will for the atheists/agnostics. One of the greatest theologians of modern times was one, and fought tooth and nail against being converted to Christianity. For the poster who said that if God would allow such things he would "rape God when he sees him...." you will repent of that when your eyes have been opened. And they will be, in this life or the next, you will see. Of course, it will be far to your benefit if you choose to see sooner rather than later.
