"And every spirit that confesseth not that
Jesus Christ is come in the flesh is not of
God: and this is that spirit of antichrist,
whereof ye have heard that it should come;
and even now already is it in the world."
1 John 4:3

According to the bible, a perverse spirit of the
wicked one, a spirit of antichrist, is already in
the world. So we have a good idea what this
person will try to bring about.
