Jesus is recorded as having said many beautiful things about love, but those are not the only sort of things he is recorded as having said.
“Do not think that I have come to bring peace to the earth; I have not come to bring peace, but a sword. For I have come to set a man against his father, and a daughter against her mother, and a daughter-in-law against her mother-in-law; and one’s foes will be members of one’s own household. Whoever loves father or mother more than me is not worthy of me; and whoever loves son or daughter more than me is not worthy of me; and whoever does not take up the cross and follow me is not worthy of me. Those who find their life will lose it, and those who lose their life for my sake will find it."1
(other versions read, whoever does not hate his father and mother is unworthy of me)
"But as for these enemies of mine who did not want me to be king over them—bring them here and slaughter them in my presence.”
Mark 4:11-12; see also Matthew 13:13-15
And he said to them, “To you has been given the secret of the kingdom of God, but for those outside, everything comes in parables; in order that ‘they may indeed look, but not perceive, and may indeed listen, but not understand; so that they may not turn again and be forgiven.’ ” [Emphasis added.]
