Luke 14:26

26 "If anyone comes to me and does not hate his father and mother, his wife and children, his brothers and sisters-yes, even his own life — he cannot be my disciple.
NIV

The word hate does not suggest positive antagonism but rather "to love less" (see Gen 29:30-31; Mal 1:2-3; and Matt 10:37). Our love for Christ must be so strong that all other love is Like hatred in comparison. In fact, we must hate our own lives and be willing to bear the cross after Him.
