Luke 12:51-53

Evidently Jesus meant that He did not just come to bring peace on earth but also division. Jesus’ earthly ministry began this division. From the time Jesus appeared preaching publicly, even households, the tightest social units, began to experience division. The difference of opinion that divided people was their beliefs about Jesus’ person and work. This situation would continue. No physical relationship would escape the possibility of this division (cf. Micah 7:6). This situation posed a crisis for the future. Historically division in the Tribulation will precede peace in the Millennium.

"Since detachment from family is another repeated theme in Jesus’ teaching about discipleship (see Luke 9:57-62; Luke 11:27-28; Luke 14:26; Luke 18:28-30), the inclusion of Luke 12:51-53 helps to make Luke 12 a comprehensive discourse on central themes of Jesus’ teaching to his disciples."
