the above sounds more like it is suggesting indifference on God's part rather than love - god makes his sun rise on the evil and the good.
Not sure how telling one to love those that are hardest to love is indifference but ok...
The perfection recommended in the verses above seem to foster a sort of detachment from real life imo. The emotions of love and hate are both healthy emotions - it is what we do with our hate that can result in badness. Furthermore there is much reward in loving those who love you and in hating your enemy. It means that one can break off from an unhealthy relationship and start a fresh. Also if one does not hate where does one find the impetus to act in self preservation or in perservation of those weaker than oneself?
I don't see it that way but lets look ta it from a purely "selfish" stand point:
Hate begets hate, violence begets violene, living with hate and unforgiveness in our lives is a horrible way to go through life, any trauma counsellor will tell you that.
You can never get closure on anything "unhealty" if you keep it "unhealty" and the best way to do that is to feed it with unforgiveness.
But, to each their own of course.
perahps a verses like the above can be contemplated as a remote ideal rather than applicable in real life. Sometimes the ideal may come closer whereas at other times it can seem far off. And as we contemplate we can notice the inherent errors and problems in the applocation of these ideals
All values start with ideals and we can see THESE ideals in, most recently, the legacy of MLK jr.
Fact is that Christ made it clear for those that follow His Word that we are to forgive and to pray for those that persecute and hate us.
Hate that leads to hate can only be broken by the power of love and forgiveness, the vicious circle of hate and violence that we see in our everyday lives have not been broken because the answers that we give are: Hate, violence, intolerance, arrogance, etc, etc.
If we see with out won eyes how THAT way doesn't work and has ever worked and we see with out own eyes how love and forgiveness HAVE changed the world for the better, then...well...there you have it.
Be the change you want to see, right?
