Don't call Left Behind Games Christian. At least the book series they're based off focuses far too heavily on an unsupported version of the apocalypse and vengeance than God and his message.

Also, @Kaymish, don't worry you're allowed your opinion and it's, sadly, an opinion probably held by a lot of people and I'm not going to hold it against you, particularly not considering the stories you here.
And I hope you realise, it's mainly a bad case of only bad news making the press. The majority of Christians dedicate their lives to loving God and prioritise helping other people over their own comfort in a small way which doesn't bring attention to themselves (naturally it doesn't always turn out like that). Just idiots make news and in the case of Left Behind, sell books.
Isaac Newton and Gregor Mendel (father of genetics) were Christian. I became Christian a couple of years ago after reading the bible a few times and being amazed at the cohesiveness and moral teachings and I've got okayish grades and study maths at a decent Uni and several people in my church run companies, are engineers, are important managers in the NHS, although you tend to get a large focus on teachers and it's wrong to judge or reject anyone in accepting them into a church value because of something stupid like intelligence. We are all born with different gifts and it's learning the humbleness to use them as best suits others that counts
