WILL THE REAL CHRISTIAN PLEASE STAND UP

So many claiming to be Christians are standing.... But; Christian's are the only religion that believe an "eye for an eye", or "getting revenge" is a sin; because Jesus said no to it, and "when slapped on the right cheek" show also the other to be struck. If told to go a mile go three times that, and you are to be used and abused by all people and nations and not complain about it. Any Christian supporting or teaching an eye for an eye as being a Christian belief is committing blasphemy. And the last chapter of rev explains blasphemy. and the book of mark says there is no forgiveness for blasphemy. Not very many are still standing!
