Everything you’ve posted is right on target, and speaks about the spirit of antichrist as it relates to anyone who denies Jesus.
But there will be a “big-A” Antichrist in the last days. Daniel and John had visions about him, and those visions agree. Both said that he will be a man of enormous worldwide power who will blaspheme God and persecute His people. They said he will suffer a fatal wound, but will be healed of it, and the world will worship him.
Obama is a nothing, a zero, a joke. But to many of his lunatic devotees, he’s a savior. I never thought I would see the day when an American president would be worshiped, but then I saw the portrayals of Obama as Jesus those nuts put up on the web.
However, I believe he, along with other factors and individuals, is being utilized to soften people up, to ready them for the “man of lawlessness”, as Paul referred to him in 2 Thessalonians. Americans, and others, exist only for their own momentary pleasure. When the state of the world becomes dire enough and a man comes along who says he can fix it all, they’ll be too eager to fall to their knees and worship him as a god. Especially when he provides “miraculous” evidence that he can rise from the dead.
Reread those verses. The “last days” were 2,000 years ago. And yes, there will be a man of sin that deceives . . . that “OLD MAN.” He’s inside all of us.
