Can you hate a tree for crushing your car in a storm?
The gospel in part is saying we are all blind, we live by our desires and own understanding and this just leads to pain and death. Now however the people around you are driven, it is as a consequence of their hearts and lostness.
Jesus accepted death, while preaching love and hope, with the power to defend himself, yet he let things go, to show how much He loved us all, and to give us a way out, not of struggling to gain what we cannot keep but to gain what we cannot loose.
What helped me love my enemy, was when I realised how we are victims of who we are, not nice people who choose to be nasty, but lost souls awash with dispair, loneliness and bitterness who put to the world as nice picture, but are eaten up with the confusion within.
