If you accept the mark of the beast, you
cannot be saved. It is an act of rebellion
against God.
So you have a choice: believe the religion
of the beast, and accept his mark; or believe
the Gospel of the Kingdom.
If you believe the Gospel of the Kingdom,
you will be saved, brought into the Kingdom
of Heaven, but you may have to give your
physical life. You may be beheaded for the
witness of Jesus, put to death because you
refuse to worship the beast.
