The Bible also says “cast not your pearls before swine lest they turn and rend you” ..so NO I don’t have to tell you anything, you fall into the pious category of a ‘know it all’.
You run the risk of judgement, since you are warned, "Judge not lest you be judged".
I am a "know it all" in the respect that I know that Faith in Christ protects me from ALL evils, including Satin himself. The "Mark of the Beast" is completely immaterial under the power of the Cross. I know this for certain. It is all you need to know. You cannot save yourself by what you do or do not do. Faith in Christ is a gift of Grace. If you don't see this as an obvious truth, then you need to examine your Faith.
So, I remind you of your Salvation through Christ and that Christ's death and resurrection totally defeated Satin, and you call be a swine? You have no problem with this, as a Christian?
