watch the video "what is the mark of the beast" by impact video ministries on yt.

here are some facts of it

1. it is NOT "666" but it CACULATES, to "666".
2. it is not for believers
3. believers will be persecuted for not getting it
4. it should not be feared

do NOT worry about this, and do not worry about being persecuted for it, for those who are persecuted for Jesus have the Kingdom of Heaven, but do NOT worry about the future, but instead work on your relationship with Jesus Christ.

but do NOT fear this, if you TRULY turn to Christ and give up your old ways, then He will save you.
