Yes, I get what you're saying, and that's a very good point (especially since it has some Biblical backing. )
But what I'm saying is this-
It's not a secret that multiple companies, organizations, etc. are working for, "pledged their alliance", etc. in that way. However, it's not literally every company that shows just a slight indication or has a weird logo.
Let's be honest. Some are really convincing, but others really just show that (not you specifically, but whoever did) are just fishing around for 6's. I'm not saying that they aren't out there. They really are, and that's the scary truth. But when you try to find trouble in everything, you will find it, and sometimes it won't even be what you're looking for.
It's smart to be vigilant, it's good. Yes, the Bible tells us to do it. But to me, there is a fine line between staying away from evil and looking for it in fast-food chain signs.
Looking for 666 in things doesn't make you a bad person, but I can tell you that looking for it in everything and accusing them of serving/being the devil with little to no evidence makes you look crazy. I, as a friend, don't want that for you. Which is why I just really ask you to consider toning it down for a bit.
It's pretty obvious that some companies and people are for 666, and I would most definitely say that there is evidence. But what about when there isn't? Are you going to poke at them too? And what if you're wrong? What if people were watching you expectantly, Hanna the Christian claims that this company or so is serving the Devil and she will prove it, and then what happens when you don't? What happens when or if it just turns out to be a false alarm? Would your work have been to expose something that may or may not have been there? Or would it have been showing the light to others and bringing them to Christ as is our mission? Will it be, Hanna the Christian was right, maybe I should consider her faith, or, Hanna the Christian was barking up the wrong tree, I knew that Christians were fools.
I really really don't want that for you, or anyone else. I'm not trying to be mean, I'm not trying to be rude, but whenever I play it out in my head that's what happens. You get hurt. And that is what happens to be who do it in real life. I get what you're saying, I get your mission. I think that it's a special burden that God has put on your heart. But, please, carefully consider what you do, what you let influence you. Maybe you're doing what God wants you to, but are you doing it the way God wants you to?
My last question is this-
You feel burdened to expose 666 and those who support it yes? You believe in staying away from evil, you believe in all that, and what you do, what you support, is what you think is the way to do that? The main question is this, have you prayed about it? Have you really taken a moment to ask God if this is how He wants you doing what he wants you to? There are things He wants us to do, but different ways to do. And speaking from personal experience, you want to do it the way He has in plan. Not your own, not what you think is best. Not even how you interpret the Bible for yourself, but through prayer. So, have you done that? Have you? Or is what you are doing right now, how you think you're following the word of God, the way that you have chosen for yourself. Is it the right way?
If it is, well, raises hands in surrender, real surrender, then I don't have any authority to tell you that God's path for you is wrong.
