Yes, scripture does speak of "on your hand and on your forehead" when referring to the "mark" of the beast. But, scripture lends out the fact that the mark of the beast is not a physical mark, but it's a mental mark. The forehead symbolizes what you think about "the world". The world meaning the people, societies, governments, desires, machinations, etc. Jesus taught his followers to be "no part of the world". Being part of it means you have the mark. Obeying all of God's commands, and being no part of the world, just living IN the world, as an alien resident, is what Jesus taught us to do. The "hand" part of it refers to your actions. What you do. Disobey any of God's commands, and you have the mark, and you are God's enemy. You have no chance at being saved, no matter what any religion (all of which are false according to God) says. They ALL lie about everything, no matter what you think. If you participate in nationalism, religion, showing off your income, immorality, dishonesty, and on and on, then you're part of the world, and you are toast.
