Rev 13:1 And I stood upon the sand of the sea, and saw a beast rise up out of the sea, having seven heads and ten horns, and upon his horns ten crowns, and upon his heads the name of blasphemy.
The world’s version of unity is compromise of many belief systems. Notice that their mantra, COEXIST, has seven letters, the beast has 7 heads.
Unity for Christians is that they are members of the body of Christ, a body that has one head and one authority, Jesus.
