To all atheists,
What are your favourite or go-to arguments against religion. One that I find myself coming back to takes the form of basically a cross-examination. I am denoted with an M for Me, and they are denoted with a T for Them. Full disclosure, my responses for "them" are self-generated and are not a representation of one conversation with a believer, but an amalgamation of many general responses to my questions.

M: It is your belief that God is omniscient and omnipotent, is it not?

T: Yes.

M: Therefore, if God created the universe, He would have known of your eventual existence?

T: I suppose.

M: If God is omniscient how can you have free will? If God knows everything that has happened, is happening, and ever will happen, He knows what you will do in any given scenario. It is impossible to surprise God. Therefore, how can you have the freedom to choose option A over B when God knows you will choose B, because God is omniscient?

T: I don't know. The scripture says He gave us free will.

M: What, then, is the purpose of judgment? If God is unable to be surprised, because God knows exactly what you are going to do, and you cannot do anything to the contrary because if so, God is not omniscient, how can God judge you for your actions? They are not your own. You have the illusion that they are your own, but if God already knew that they were going to happen, and he did nothing to stop them, it is as though he prescribed and endorsed them. How can God judge you for something you have no control over? You have no control over your actions, because if you did, God would not be omniscient since he would not know what you were going to do. It is unethical for a god to judge someone over actions that they could not help, and dare I say almost forced to partake in, since at any point God could have decided not to allow you to make that decision.

T: God doesn't need to know what you will do. God could instead know of every single possible hypothetical outcome depending on which hypothetical decision you make.

M: But that's not true omniscience is it? If He truly knew everything wouldn't He know which of these outcomes was going to occur? And he would therefore know the result of that outcome as the only true outcome?

T: I suppose it's not true omniscience, no.

M: Then God, having full knowledge of the course of your life and all your actions, must want them to happen, or at the very least, does not care either way, or He would stop them from happening. How then, can he punish you for eternity in Hell or laud you in Heaven when it was by His hand you acted and could not stray from the path that He formed in his head?

T: I don't know how he can do that...He's God. He can do whatever he wants or thinks is right.

M I refuse to submit to a being who demands my respect when he as already decided millennia before my existence what I will do and where I will be for eternity after I die. He does not know me, he does not know how I will act in a certain scenario. I can only act in the manner in which God dictates I should. Why then, should I be condemned to Hell for acting in the way in which God intended me to? How is that in any way ethical?

T: You shouldn't. It's not. But the scripture doesn't really say that, it says (insert quote here).

M: I also turn to a quote from Epicurus, "Is God willing to prevent evil, but not able? Then he is not omnipotent.
Is he able, but not willing? Then he is malevolent.
Is he both able and willing? Then whence cometh evil?
Is he neither able nor willing? Then why call him God?"

That's usually the end of the conversation. As soon as I raise the ethical dilemma of judgment of one's actions when one has no control I can see the confusion in their eyes as they rack their brain to figure out an answer that works with their world view rather than amend their world view. Some have lashed out at me. Others have come to me later saying that they are now atheists. I don't actively campaign against religion. But if people want to debate, I will. What do you all think of this argument? How can I make it stronger?

Thanks,
Brian
