Matt 10:34; "Do not think that I came to bring peace on the earth; I did not come to bring peace, but a sword.
Matt 10:35; "For I came to SET A MAN AGAINST HIS FATHER, AND A DAUGHTER AGAINST HER MOTHER, AND A DAUGHTER-IN-LAW AGAINST HER MOTHER-IN-LAW;
Luke 12:51; "Do you suppose that I came to grant peace on earth? I tell you, no, but rather division;
John 9:39; And Jesus said, "For judgment I came into this world, so that those who do not see may see, and that those who see may become blind."
John 10:10; "The thief comes only to steal and kill and destroy; I came that they may have life, and have it abundantly.
John 12:27; "Now My soul has become troubled; and what shall I say, 'Father, save Me from this hour'? But for this purpose I came to this hour.
John 18:37; Therefore Pilate said to Him, "So You are a king?" Jesus answered, "You say correctly that I am a king. For this I have been born, and for this I have come into the world, to testify to the truth. Everyone who is of the truth hears My voice."
1 Jn 3:8; the one who practices sin is of the devil; for the devil has sinned from the beginning. The Son of God appeared for this purpose, to destroy the works of the devil.
