no, dear, its not. not that god is gonna pay any attention to. the marks are already there. its in what people think and do and say.
want to avoid the mark? do this:
Romans 12:2
And be not conformed to this world: but be ye transformed by the renewing of your mind, that ye may prove what is that good, and acceptable, and perfect, will of God.
throw the electronics away.
spend the next year in solitude, reading the bible, prayer and fasting and meditation. your questions will be answered by god then, instead of men, WHO LIE.
