Think about it. He was hated, tortured and executed while he was on earth. Why? What did he do that caused (and causes) so many to hate him?I have not come to call the righteous but sinners to repentance. (Luke 5:32)
He shows us what we really are, and it's not "righteous". I hate it when He does that.
Of course, admitting our sins, and being repentent, requires us to subject ourselves to God. Pride often battles against that -- which is why pridefulness is such a grave sin.
Believers know why he is hated-- but it shouldn't make any sense for the unbeliever. They don't believe he is God (so they say), they don't believe he arose, he was only a good teacher who taught love and tolerance and peace and flowers. In hating him, therefore, they acknowledge (perhaps not consciously) that
He is alive
He is God
They are not reconciled with him
They reject him
They will be judged by him.
