There are some things theists don't have answers to. While a few might have it all figured out, other believers struggle with questions like:
Did Adam have a bellybutton?
If disease was created when Adam and Eve left the garden, does that mean Noah and his family were carrying all hereditary human diseases?
When the Earth stopped spinning for Joshua to win a battle (Joshua 10:12-14), why did no one else keep a record of an unusually long day or night?
If God isn't sexist, why does He say women are unclean for longer after giving birth to a girl
rather than a boy? (Leviticus 12:1-5)
Why did God wait 13.7 billion years to get around to creating His favourite species?
If Earth is much younger than scientists say, does that mean the continents split and went rushing away from each other, only to screech to a near crawl just before humans started taking notice of their speed?
Is there free will in heaven? If there is, and we'll be perfect (or at least not sin), how can sins on Earth be blamed on our free will?
Why did God create a planet with earthquakes, tsunamis, hurricanes and other factors designed to cause suffering?
It can't be blamed on us if these things existed before humans even came on the scene.
If God is the grand architect of billions upon billions of stars, planets and galaxies, with unlimited power to do anything, why do some of His demands seem so immature and petty by comparison? For example, demanding people burn animals so He could enjoy the smell, and insisting they put their heads under some water to prevent damnation.
If God already has a grand plan, what is the point in us praying for Him to do things? He'd do it or not regardless.
If God designed our brains to believe whatever we're told as children by our parents, doesn't this give an unfair advantage to those who happen to be born in the right time and place to be taught His true religion?
When a theist does become stumped by something (doesn't have to be something in that list, think of something you'd want to ask God if you met Him), often enough they'll say 'We can't be expected to know everything, we'll have to wait to find out. Perhaps I can ask God when I go to heaven, but it's okay not knowing everything now.'
Is it really okay for people to think that way when they come across a gap in their knowledge? There is a solution to this. The solution is Jod. Jod is a time travelling Japanese man, born in the year 4444. He travels through time and space in his anti-aging time capsule, interfering or helping God out, depending on his mood. His existence answers everything we ever wanted to know.
Nobody else on Earth kept a record of the sun appearing to halt for a whole day because Jod of the Japs was using the time capsule's all encompassing neuro modifier beam to give everyone normal day delusions.
God waited nine billion years before making our planet because Jod of the Japs had convinced Him to have the longest cosmic chess game ever. It took God another 4.7 billion years to make humans because Jod challenged Him to a rematch.
The Biblical verses showing God as sexist were snuck in by Jod of the Japs. God got tired of taking them out all the time so He left it in the end.
It was Jod of the Japs who used the time capsule's telepathic communication ray to convince some humans to burn animals because he missed the smell of barbeques (a fire hazard on time capsules).
I don't know why, but I find most God believers aren't convinced. They say things like 'Nobody knows, not even you. You're making stuff up because you can't live with not knowing. It would be stupid to think we should know as much as our descendants. The early Jews didn't know Jesus' blood and flesh was going to be represented by wine and bread, or that he'd be returning anytime now. It all had to be revealed. Knowledge comes with time, why can't you be patient?'
That's right. They can't disprove Jod of the Japs, and it even answers every question we can have, but they'd rather stick to their ignorance than accept he exists. They demand proof, when proof is all around us. How else can these mysteries be explained? That's proof enough.
They're always changing their minds too. First they think God made everything exactly as the Genesis account says, now they think it was just an easier way to understand things because humans were less knowledgeable in Biblical times. How can the waiting for God method ever be trusted when God's answers keep changing?
At least some of us are willing to use common sense in accepting Jod of the Japs has done all these things. It appears others would rather be stubborn and cling to unanswered mysteries.
