Follow the Lamb

those who have received the mark of the beast on their foreheads

persecution and threat of martyrdom

the incompleteness of 666

the dragon and his first beast whose habitat is the unruly sea
the Lamb who stands on firm and holy ground

the completeness of 144,000  

security in Mount Zion

those who have the name of the Lamb and of his Father written on their foreheads

I really like how John Stott writes about the contrasts between Revelation 13 and 14 in the Bible study book we are using.   These are all his phrases, I just rearranged them.
