I have often pondered that myself but keep coming back to the fact that it has to be something seen and verifiable or how do they keep people from buying and selling?
I usually come back around to the concept that the Mark of the Beast is a symbol (visible or not) of one's commitment to Satan. And any actions that follow (like supporting Obama) would have benefits...just as a commitment to God (as evidenced by actions) would have consequences (like being investigated by the IRS).;-)
From my studying and revelation, God’s calendar is truly different from the Gregorian calendar... His calendar as scripture detailed was using both the moon and the sun... the calendars today only use the sun.... if you can’t find the start of His months, you can’t find his sabbath.... or the feast days...
His calendar is not a five day work week and two days off..
If you follow His timekeeepng, days like thanksgiving and Christmas and easter are holy days that have been man made,... and it is now easier to buy and sell on eastter and thanksgiving but hard on Christmas... it may be a future time when all things will be closed so no one can buy and sell less you buy into these days .....
Life altering to say the least when I was studying passion week and Leviticus 23 and moses and the wilderness....
Someone wanting to observe His calendar has to use vacation days for His sabbath as His calendar doesn’t tie into the Gregorian..that calendar floats into His.... new moon and month same word in scripture in a number of passage... and you cont from then... He never named days, He numbered them...
Spiritual mark is a calendar, maybe time itself as a counterfeit to God’s timekeeping... who doesn’t use it? More confirmation when I studied Jericho and the seven day march and he fact they didn’t violate a sabbath.someday the world may call on one sabbath universal or maybe take three day off where you can’t buy or sell.. I know again, it is difficult to buy or sell on Christmas... and before this study and prayer, I thought Christmas should have stuff closed... not anymore.. the more things open, the better...
Of course, this doesn't identify the Beast, but it does provide a huge clue (if true) as to the Mark itself.
