Christianity and Politics

What do you think about how Christians should respond to the political world? Well I can tell you in a perfect world we should all think the same, and vote the same as Christians. God has planned a way for us to run a world thus in the bible and we as Christians should stride to follow his rules. Tell me what you think about this issue???? What's your view on abortion?? Gay Marriage???? Etc. feel free to tell me what you think, please know that any inappropiate responses will be DELETED AND NOT RESPONDED TO. Thanks!
