I always imagined God, back when I was a theist (so very long ago), as a kind of bestial force. Kind of like Golding’s ‘Lord of the Flies’, you know, the big monster all of the little kids ran away from and the big kids built a totem to (sow’s head on a stick attracting flies is the imagry here). I think that describes the mythos all deities sprang from. When I hear of somebody describing god as beautiful, I think of Jack the Ripper. If one thinks there is a god, which I do not, how can one think of a peaceful god when people like Jack the Ripper can exist? Anyway, it is a force. A hungry, beast-like force.
It is amusing, I must say! 
Oh, the hubris of beings who, unable to find meaning within themselves, invent deities to validate their existence. Oh, it is wonderful.
Unable to provide evidence for their faith, they declare the lack to be ultimate proof. Unable to define their hypothesis, they deduce volumes from their innocence.
God is so _______

There ya go! You got it! 
It is always a stalement. Reason is an insufficient epistemology for knowing Truth.
I don’t need to prove my existence, Lib. (What point would such a proof even encompass?) I only need to experience it, which I do, daily. And if you say that’s all I need to do with God’s, I’m going to poke you in the eye with something pointy. A carrot, at least.
Of course.
It is, however, the most reliable tool we have for detecting Falsehood.
God makes everything turn out all right…
…eventually. Until then, we’re on our own.
Reading the Gospels, Jesus’ dominant personality trait appears to be his compassion. Where you take that depends on what you already believe, I suppose.
A comment for the atheists who’ve posted here: with all due respect, if someone started a “who was the greatest baseball manager ever?” thread, for instance, and people who thought baseball was deadly boring repeatedly posted on the thread to that effect, I would consider that to be rather rude.
I think you can draw the analogy.
God is whatever a person wants Him (or Her) to be.
Read into this what you will…

And daily, I experience God.
I’m not saying what you need to do, Phil. You have your own journey. I cannot see from your reference frame; that is, I cannot experience your consciousness.
Satan
That is exactly right. You have said in one sentence what I have been trying to say for months!
With all due returned respect, Rufus, the question was asked of all posters, not merely theists. You can argue that it is implicit in the question, but my opinion is as valid as anyone else’s on the topic. I do not believe deities exist, therefore I believe their personalities also do not exist.
All very interesting responses so far. Some I expected, some I didn’t.
Just to clarify my question one more time for anyone else who chooses to respond: I’m not asking about traits of God like omnipotence. I’m asking about personality. Does He laugh and tell jokes? Is He fun to be around? Is He harsh and antagonistic? Is He mean? That kind of stuff.
Let me also clarify where I’m coming from as I share. I am not describing God’s personality in the abstract. I am describing a God that I have known personally for the past 26 years. I have seen His personality in action. I am also contantly amazed at how vast He is! I learn new things about God’s personality each year, and I suspect that I always will. I am not claiming that I or anyone can know all of God’s personality. That’s why I am only asking for the one or two things that stand out to you.
I would like to inject into this discussion another aspect of God that you might not have thought of before.
God loves you. You’ve probably heard that all your life to the point that it’s become trite. But have you ever stopped to think about the ramifications of that statement?
When you love someone, you make yourself vulnerable to them. You especially make yourself vulnerable if you declare your love. Remember the Seinfeld episode where George was going to say “I love you” to his girlfriend because “everyone else gets to say it, why don’t I get to say it?!?” Jerry asked, “Are you confident in the ‘I love you, too’ return?” George wasn’t so confident. Yes it was silly comedy but we remember that scene because we can relate. Declaring your love for someone makes you vulnerable … because what if they don’t love you back?
I was about to say “God is a lot like us” but really I’ve got it backwards. We are a lot like God! Remember, He made US in HIS image. God, also, makes Himself vulnerable when He declares to you personally …
“lucie, I love you so much that I want to have a personal relationship with you”
“DavidB, I love you so much that I want to walk with you through the trials of life and help you through them”
“Satan (the poster that is!), I love you so much that I sacrificed the life of my own Son just so you could know me”
God declares His love for each one of you reading this individually. The vulnerability comes because God gave you a choice as far as your response, which only makes sense. What kind of love would it be if He forced Himself on you? You have a choice to receive His love.
So the character trait I want to bring up in this post is … sadness. There is a large part of God that is terribly sad. He regularly throws His arms out to those who are needy and hurting and says “I love you!” In response, many times, He gets cursed at and spit upon, just like when He was on the earth. I know this is true, because I’ve felt God’s sadness in my own heart as I’ve seen people who just outright rejected Him.
Don’t be one of those. Receive God’s unconditional love!
No thanks. I prefer my illusions to be more original. 
RTF:
I understand your position, and I respect hat I believe you are trying to say. If you simply assure me that you will likewise admonish any who bring the subject of “baseball managers” into threads which do not specifically address them then I will accept your rebuke and depart forthwith.
FriendofGod, are you trying to express an opinion or convert people? If the former, feel free. Nobody wants to stop you. If the latter, you are showing tremendous hubris and little sense. I’m a tolerant man. But this is a debate, not a church. Express an opinion or get out.
Utopia is correct.
If God exists, in the sense of an all powerfull creator of life, the universe, and everything; he is a being beyond human comprehension. Anything so vast and powerful would not have a “personality” in any meaningful sense. An ameoba has a better chance of understanding Hegel than we would of understanding God.
Also, Derleth, I’m not particularly upset by Friend of God’s attempts to convert anyone. Everybody here is trying to “convert” others to their way of thinking. What’s the point of discussion otherwise?
I bet God is a smartass. Although, if your were omnipotent wouldn’t you be?
“God is gay.” -Jesse Ventura, Late Night with Conan O’Brien
Okay, okay, I’m sorry, I’m sorry! I couldn’t resist putting that in when I read the OP (and, incidently, Jesse Ventura didn’t really say that, it was part of a comedy sketch).
Anyway, to be serious…
I would imagine that whatever higher power exists-- God, if you will-- would want to keep any sort of influence on our lives to a minimum, lest he (or He) cause us to lose our free agency. I would imagine, if our existence was meant to allow us to grow spiritually, he’d want us to get by on our own as much as possible. The only times he’d intercede would be to stop other outside forces from interfering with our development.
Whoa, I’m having a spiritual moment… better go drink some Josta and count to ten…

Of course, free will is not equivalent to God existing. So I’m not totally sure what you’re point it (or if you even have one).
RTF: FoG asked a question. There were no qualifiers saying that only believers could answer.
FoG said:
I doubt you will get many answers like this from people who actually believe in God. I mean, if you believe, you probably don’t believe he is mean and antagonistic. I suspect that you expected people like me to answer in this way. The problem is that first I would have to believe in him. I have explained to you in other threads that if your God actually existed, as you described him, I would say he is mean and antagonistic and the like. But, again, I don’t think he actually exists – especially as you describe him.
My point was the point I made, namely that “God’s unprovable nature is the clearest proof that we have free-will.” I did not make the point that free-will is equivalent to God existing.
Oh. OK. Well, then, I guess that’s that.
(I’m just so used to you having a hidden meaning behind what you say… )

Consider the “-” sign in math. It can mean a negative number; it can mean an additive inverse; or it can mean a subtraction operation. Context is everything.
