No, someone does not believe in the Christian religion because it doesn't make sense. It is self-contradictory, it has so many contradictions that it's impossible to accept it without feeling like an idiot. You could probably find zillions of contradictions, here are some of my favorites:
If god is almighty and sees the future, how come he didn't think of that on damn tree in the middle of paradise?
If god is perfect, how come he failed at making man perfect too?
If god is almighty and the enemy of Satan, how come he doesn't just kill Satan?
If god is good and almighty how come there are so much innocents suffering in the world? Probable answer: because he tests people. But if he sees the future it's needless.
And so on, you get the picture, when the clerics are done sorting these questions out drop me a note.
The tree was a test for mankind which Satan made Adam and Eve fail. God had to stick to his rules and the consequences ensued. The tree was neccessary because Men are to have free will. God wants them to love him and that's not possible when there's no alternative.
There's a whole set of rules, that's why he won't kill Satan just now. Christians believe mankind isn't innocent per definition since they were cast out of Eden. All the bad we see in this world is because of that and because Men has free will and Satan keeps pulling strings to keep them away from God. In this sense, Satan tempts People and makes them sin which in turn can't make them come to God.
God's final answer is Jesus who presents Men with a solution to escape Satan's grip and position themself with God.
That's what christians who want to make sense of it all believe anyway ;-)
The only real contradiction I see is that God says he's perfect but still created mankind and wants people to love him.
Here is another plot hole, if god is indeed almighty he could simple strike down all foes instantly. And what are the other angels doing? don't they have free will are they just robots? If Satan is indeed a fallen angel than God, really screwed up, which is again a problem because he is almighty and all knowing.
> The tree was a test for mankind which Satan made Adam and Eve fail.
If god is almighty and all knowing and have created man, and even sees the future, he would have known the outcome in advance, so basically there would have been no reason to do it.
> There's a whole set of rules, that's why he won't kill Satan just now.
Then God is probably not that almighty if he has to stick to rules, instead of hurling a lighting bolt or a ball of fire at Satan.
I am not saying that God can't exist, I am saying that the Christian definition is impossible, a god can't be all of these at once:
- all knowing(could see even the future)
- be good/nice whatever
- be perfect
- have free will
And I don't even want to get into Jesus, that would be a huge topic by itself.
>If god is almighty and sees the future, how come he didn't think of that on damn tree in the middle of paradise?
He made that tree. So, I'd say He thought of it. He made it for the precise purpose of giving mankind the ability to choose. If we didn't have the ability ability to choose God, then our serving Him would be pointless, since we'd essentially be mindless drones. God wanted people to have the ability to love Him of their own free will.
>If god is perfect, how come he failed at making man perfect too?
Adam and Eve were perfect. Then they chose not to be perfect.
>If god is almighty and the enemy of Satan, how come he doesn't just kill Satan?
Because Satan still serves a purpose. I'm not entirely sure of all of it, but the main purpose seems to be to provide an obvious choice for us. God or Satan, who do you want to serve?
>If god is good and almighty how come there are so much innocents suffering in the world? Probable answer: because he tests people. But if he sees the future it's needless.
Testing is part of it. But testing is for our benefit, not His. Like you said, He knows the future, so He already knows what we will do.
The larger part is that humans can make choices, see my first answer. And thus, humans make choices that hurt others. The airplane mechanic who missed the problem that cause random flight to crash made the choice not to be thorough. The criminal chose to rob that bank and shoot the teller.
So, bad things happen to good people because good and bad people make bad choices.
As for natural disasters, they happen because humanities choices effect more than just humanity. The entire world was perfect before Adam sinned. When he sinned, the entire world broke.
You can always find something that is not right.
> Adam and Eve were perfect. Then they chose not to be perfect.
According to the bible, they didn't know exactly what will happen if they eat from the tree, hence they didn't chose, they were tricked. If they were perfect they should have asked God before they tasted it. The story kind of makes me feel that humans were created to be fools according to the bible.
The story condemns curiosity which is one of the best human traits, without it, we'd be still in the stone age. And of course a hood 'nerd' has to be curious.
> God wanted people to have the ability to love Him of their own free will.
Why not just create love, it would save a lot of time, I know love is not a substance to us... but someone almighty could surely create it.
> Because Satan still serves a purpose. I'm not entirely sure of all of it, but the main purpose seems to be to provide an obvious choice for us. God or Satan, who do you want to serve?
This sounds like God is playing a game with Satan, a very cruel game if you ask me and pointless too, because God knows how it will end anyway. And it also seems that he doesn't kill Satan because then he'd be bored.
About the free will thing:
Let's say you create robots and program them slightly differently. And let then interact with each other. In their view they have free will, in your context however you know exactly what they gonna do, you could calculate it all in advance. So in the end we may not even have free will, we are just complicated.
Se my other comments here, I am not saying that God does not exist, I am saying that the Christian religion is probably wrong about it, it can't be that way.
