Mike,
As I understand you, you assert that the reason humans suffer in this life, is because God wants to test us. If we pass the test (that is, do our best to live 'rightous' lives), then we will be perfect in the next life.
Obviously, you have then rejected the "free will" defence for the existence of God in the face of evil.
The "this life is only a test"-theory is also faulty, for a number of reasons. Nobody has demonstrated what exactly is being tested. Humans live under very different circumstances. Those who are born in a Buddhist, Hindu or Muslem country almost invariably end up in these traditions. Do they go to hell by default? Most people have also been born in utmost poverty, without any life that can be considered a test of anything, except dying. What exactly was it God wanted to test, given that he created humans so at least half of all children dies shortly after birth? Did he want to test how effective the bacteria and virus he had created was at killing humans?
If God wanted to test anything, the present world is almost the worst testing grounds imaginable. Most people die and suffer from random causes: natural disasters, illness, epidemics, violence from outsiders. Surely, it would be much better for God to test humans in an envirionemtn where the playing field is even, and when people have the time and energy to do anything else than survive (and, rather, failing at survival).
Naturally, sooner or later all Christian apologetics falls into the Last Restort theory of ethics (more commonly known as the Divine Command Theory of Ethics):
God cannot act unrighteously because God decides what is right and wrong.
This may seem like a clever defence, but it has an in-built trap, and this is the reason almost no serious theologists resort to it. In fact, Plato (or Socrates) demolished this argument around 2400 years ago, so those who use it today are very badly updated on philosophy and ethics.
Let’s look at the Divine Command theory of ethics. It holds that "morally good" means "commanded by God" and that "morally wrong" means "forbidden by God." It’s that simple. There are many objections to this theory, and this is the reason Christians generally don’t really hold it. Some, like you, appeal to it when they are faced with tough questions, but that’s just a convenient ad hoc position.
If this theory is true, it follows that God’s moral choices are arbitrary. By that I mean that there is no outside definition or judgment of good or evil that can be used to evaluate God’s decision. So, if God had decided that murder, rape and torture was morally good, then it was good. Theists cannot possibly deny the possibility that God could have so ordained, because then they would have to admit that their moral judgments are really independent of God’s. At this point, practically everyone understands that the Divine Command theory of ethics is totally absurd.
Christians generally hold that God commands certain things because these are good. But under this theory, it’s the other way around. Before God commands that helping old ladies over a street is good, it is not good. Before God says that raping young girls is wrong, it is not wrong. Further, it follows from this theory that God cannot justify his moral decisions. If God gives a reason for moral decisions, then there are objective reasons beyond God’s arbitrary decisions (ie. they are not arbitrary at all), and there are standards beyond God’s command on which His moral decisions are founded.
A refutation of this argument can be found in Plato's Euthyphro, where Socrates asks a question that is an effective refutation of the Divine Command theory. Expressed in monotheistic terms, it could be summarized: "Are certain actions good because God commands them, or does God command them because they are good?" Michael S. Valle, in the essay "A Critique of the Divine Command Theory of Ethics," (I have downloaded it from the Net, but now that URL is invalid) and referring to Baruch Bordy, lists the argument like this:
1. Let us suppose that it is the case that there is some action A that is right (wrong) only because God wants us to do (refrain from doing) it.
2. There must be some reason for God's wanting us to do (refrain from doing) A, some reason that does not involve God's wanting us to do (refrain from doing) it.
3. Therefore, that reason must also be a reason why A is right (wrong).
4. So we have a contradiction, (1) is false, and either there are no actions that are right (wrong) because God wants us to do (refrain from doing) them or, if there are such actions, that is not the only reason why those actions are right (wrong)
The attempts made to refute this argument have not, to put it mildly, been convincing.
The Bible itself also clearly refutes the Divine Command theory. When God explained his punishment over Sodom, Abraham demonstrated that he believed that right and wrong existed apart from God:
Ge 18:23,25 "Then Abraham approached and began to say: "Will you really sweep away the righteous with the wicked? … It is unthinkable of you that you are acting in this manner to put to death the righteous man with the wicked one so that it has to occur with the righteous man as it does with the wicked! It is unthinkable of you. Is the Judge of all the earth not going to do what is right?""
Is it not indeed? And from the existence of suffering and evil, something that would be unthinkable if there were an all-powerful, all-benevolent Judge and God, we can conclude that such a God does not exist.
Lastly, let me tell you exactly what I mean when I say that the existence of evil, in particular natural evil, is impossible to harmonize with the existence of the God of classical theism. I have quoted this example earlier on H2O, from a famous Usenet article that really nailed the issues, but it bears repeating at this point:
Let me quote a real-world example just to put this in perspective. I don't know if you know this, but there are viruses in the world that make AIDS look just like a picnic. They're called hot viruses, and these things are nasty. There was a story on them that ran in the Seattle Post Intelligencer on December 26th, 1994. I'm going to quote an excerpt from it. This is the description of someone coming down with this virus:=======
The headache begins typically on the seventh day after exposure to the viral agent. On the seventh day after his visit to Kittiam Cave in January 1980, Monet felt a throbbing pain behind his eyeballs. The pain begin to circle around the inside of his head. It would not go away with Aspirin. And then he got a severe backache.
On the third day after his headeache started, he became nauseated, spiked a fever and began to vomit. At the same time he became strangely passive. His face lost all appearance of life. and set itself into a motionless mass, with the eyeballs fixed, paralytically staring. The eyelids were slightly droopy, and the eyeballs seemed almost frozen in their sockets where they turned bright red. The skin of his face turned yellowish, with brilliant starlike red speckles. He began to look like a zombie. His personality changed and became sullen, resentful, angry. His memory seemed to be blown away.
When a hot virus multiplies in its host, it can center the body of the virus particles from the brain to the skin. Experts then say the virus undergoes, extreme amplification. By the time extreme amplification peaks out, an eyedropper of the victim's blood may contain a hundred million particles of virus.
In a waiting area at the Casualty Department, Nairobi Hospital, Monet appeared to hold himself rigid, as if any movement would rupture something inside him. His blood was clotting up, and the clots were lodging everywhere: his liver, kidneys, lungs, hands, feet, and head. In effect, he was having a stroke throughout his whole body.
Clots were accumulating in his intestinal muscles, cutting up the blood supply to his intestines. The intestinal muscles were beginning to die. The intestines were starting to go slack.
His personality was being wiped away by brain damage. Monet sat silently, waiting to receive attention. Suddenly, it went into the last phase. The human virus bomb exploded. Military biohazard specialists say that the victim is crashed and bled.
Monet became dizzy and utterly weak, and his spine went limp. He is going into shock. He leaned over, head on his knees, and brought up an incredible quantity of blood from his stomach. and spilled it onto the floor, with a gasping moan. He lost consciousness, and pitched forward. When he pitched foreward onto the floor, the only sound was the choking in his throat, as he continued to vomit while unconscious. Then came a sound like a bed sheet being torn in half, the sound of his bowels opening and venting blood from his anus, those mixed with intestinal lining, he sloffed his gut, Monet had crashed was bleeding out.
Having destroyed its host, the virus was now coming out of every orifice, trying to find a new host.
=======
Now, I ask you, isn't is possible that God could have made this guy suffer just a little bit less? Maybe just bled out of his nose? Of course He could have. This means that there could be less harm in the world than there actually is. But this should not be possible if God were omniscient, omnibenevolent, and omniponent. So, He must lack at least one of these characteristics. However, all of these characteristics are essential to God. A being is not God if it lacks one of them. Hence, God does not exist.
