Matthew 10:34-39
34 “Do not think that I have come to bring peace on the earth; I have not come to bring peace, but a sword [of division between belief and unbelief]. 35 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; 36 and a man’s enemies will be the members of his [own] household [when one believes and another does not].
37 “He who loves father or mother more than Me is not worthy of Me; and he who loves son or daughter more than Me is not worthy of Me. 38 And he who does not take his cross [expressing a willingness to endure whatever may come] and follow Me [believing in Me, conforming to My example in living and, if need be, suffering or perhaps dying because of faith in Me] is not worthy of Me. 39 Whoever finds his life [in this world] will [eventually] lose it [through death], and whoever loses his life [in this world] for My sake will find it [that is, life with Me for all eternity].
Luke 12:49-53
49 “I have come to cast fire (judgment) on the earth; and how I wish that it were already kindled! 50 I have a baptism [of great suffering] with which to be baptized, and how [greatly] I am distressed until it is accomplished! 51 Do you suppose that I came to grant peace on earth? No, I tell you, but rather division [between believers and unbelievers]; 52 for from now on five in one household will be divided [over Me], three against two and two against three.
53 They will be divided, father against son and son against father, mother against daughter and daughter against mother, mother-in-law against daughter-in-law and daughter-in-law against mother-in-law.”
