The mark of the beast in revelation can be found on many things in the modern world. Most of us have taken them unknowingly and in ignorance. We are surrounded by them. You may find them in your home, office, car, and on your clothing. It is important to recognize and root them out of our lives as much as possible to survive what is coming. While the ultimate, final mark of the beast may be some form of implanted microchip or other technology that is forthcoming, make no mistake, his mark is all over our lives, but we can take steps to remove them. The Lord tells us that His people are not to compromise with evil in any way.
Deuteronomy 7:26 Neither shalt thou bring an abomination into thine house, lest thou be a cursed thing like it: but thou shalt utterly detest it, and thou shalt utterly abhor it; for it is a cursed thing.
