During my life time their have been around a hundred predictions of when the world will end and all those dates have come and gone and we are still here.  .https://en.wikipedia.org/wiki/List_of_dates_predic...

So Chuck why would I believe you?  

Said every nutter for the last several thousand years...

Let's first make certain we know precisely what it is before we get our collective panties all knotted up.

The biblical mark of the beast transpired during the dark/middle ages. It wasnt anything as you imagine. So relax. 

That which is ASSerted without evidence IS dismissed without evidence.

I don't think I will worry much about "your" beliefs.

We all will face bad things ahead (so eventually we are all in this together), and it looks like those who get out of here the earlier the better. Though mainstream pastors are lying to their congregations, telling them that they will be raptured away, before anything bad happens, this is not what the Bible says. There is a persecution against God's people, however, the New World Order is a system lasting less than 10 years, and things get worse and worse as time goes on.... and those who side with the system, will experience worse things than what they put the children of God through - as God will pour out on that system double for her evil.

There is one plague that lasts 5 months long, and people will cry out to die, but God will not let them. What is worse than death.... living and wanting to die. As time goes on, hearts will grow colder towards one another, and people will betray each other.... it will be troublesome times -- though there be promises of peace and security, though when people think they are finally safe and secure, then destruction will come, even for those who are in their prosperity. Those who do not live according to peace cannot give and provide peace, for they are its destroyers.

The righteous perisheth, and no man layeth it to heart: and merciful men are taken away, none considering that the righteous is taken away from the evil to come. - Isaiah 57:1, KJV

“And I heard a voice from heaven saying unto me, Write, Blessed are the dead which die in the Lord from henceforth: Yea, saith the Spirit, that they may rest from their labours; and their works do follow them.”  - Revelation 14:13, KJV

“There is no peace, saith the LORD, unto the wicked.”  - Isaiah 48:22, KJV

8 The way of peace they know not; and there is no judgment in their goings: they have made them crooked paths: whosoever goeth therein shall not know peace. - Isaiah 59:8, KJV

3 For when they shall say, Peace and safety; then sudden destruction cometh upon them, as travail upon a woman with child; and they shall not escape. - 1 Thessalonians 5:3, KJV

The "mark of the beast" was in Emperor Nero's time.  You are a bit late - over 1900 years in fact.
