{The world would love its own} (ho kosmos an to idion
ephilei). Conclusion of second-class condition (determined as
unfulfilled), regular idiom with an and imperfect indicative in
present time. {But because ye are not of the world} (hoti de ek
tou kosmou ouk este). Definite and specific reason for the
world's hatred of real Christians whose very existence is a
reproach to the sinful world. Cf.  7:7  17:14  1Jo 3:13 . Does
the world hate us? If not, why not? Has the world become more
Christian or Christians more worldly?
