The Antichrist will imitate God and mark
his followers Revelation 13:16-17 :
"And he causeth all, both small and great,

rich and poor, free and bond, to receive a
mark in their right hand, or in their
foreheads:
And that no man

might buy or sell,
save
he that had the
mark, or the
name of the
beast,
or the number of his name."

It is a mark of doom!
