He came not to send peace, but a sword...

Matthew 10:32-40, KJV

32Whosoever therefore shall confess me before men, him will I confess also before my Father which is in heaven.

33But whosoever shall deny me before men, him will I also deny before my Father which is in heaven.

34Think not that I am come to send peace on earth: I came not to send peace, but a sword.

35For I am come to set a man at variance against his father, and the daughter against her mother, and the daughter in law against her mother in law.

36And a man's foes shall be they of his own household.

37He that loveth father or mother more than me is not worthy of me: and he that loveth son or daughter more than me is not worthy of me.

38And he that taketh not his cross, and followeth after me, is not worthy of me.

39He that findeth his life shall lose it: and he that loseth his life for my sake shall find it.

40He that receiveth you receiveth me, and he that receiveth me receiveth him that sent me.
