Well Teddy, first of all do you really want me to answer all those questions or did you just want to shove it in my face?? Well, for whatever reason I'll answer them for you. First to most of your "How do you know" Questions I need scripture to give it to ya word for word and I don't have time for that. Lookit up in the Bible or ask your preacher. And have you ever heard that old hymn "Jesus loves me this I know, FOR THE BIBLE TELLS ME SO" Okay, you said you already know the ten commandments and there are so many other rules to follow! You are right on target, but the ten commandments were just an example for geminiangel!!
Your first question: Are you saying to follow God's nd if we don't we are dissobeying God and God will be upset.
Well, here's an example: If your parents specifically told you not to be out at night past 12:00 and you stayed past 1 would they be upset?? The point is YES God will be upset. But you can ask for forgiveness and not do it again and you will be forgiven.
Next question: What happens if we dissobey God?
Hmmm well, I guess that's between you and God!! He sort of talkes to you in your self concious you just have to listen.
What if we don't beleive in the Bible but believe in God???
Well, if you don't believe in the Bible than you don't believe in God, because the Bible is God'd word. Everything in the Bible was written by people who God told them what to write or in the New testament wittnessed it(because most of them were deciples.)
What happens to people who don't believe in God?
They do not get to spend eternal life in Heaven.They go to Hell. I know this because the Bible says

this isn't exact wording just the point) They who follow Christ shall spend eternall life in heaven but they who do not shall be cast in to the fires of Hell.
Because THE BIBLE SAYS. Do you really think that the Bible is just some scam that a loser a really really long time ago wrote to amuse people???? The Bible was written by people who God sent dreams to.he told them SPECIFICALLY what to write. Most of the New Testament is written by deciples.
If we are not Christain but another religion do we go to Hell?It all depends if you are talking about Jewish people or Unitarianism. Jews believe in God they are really like Christains. On the other hand others do not follow Christ sooooo what do you think?? Duh! And Oh BECAUSE THE BIBLE SAYS SO. Thank you for all the questions. They made me think about what a christain really is and if you have any more questions just holla!!If I didn't answer all of them ask again!! And Oh!!! I almost forgot, YOu asked how is God helping with the war. Think about this really you have to answer this question yourself if you honestly do not know. God Bless you!!!
