Religion has inspired and driven people to do truly horrible things to others, and for what? Basically because they think their invisible friend wanted them to and that he'd eternally reward or hurt them based on if they obeyed him or not.
....But that Peace on Earth is only for 7 years. It is an artificial peace brought to the world by the Antichrist and the False Prophet yet to be revealed. Jesus Christ is the True One Who will bring permanent peace to His believers.
