When we are dissatisfied with things as they are, or suffer and know pain, we begin to imagine what the world would be like if things were different--if there were no hunger or thirst and all tears were wiped away (Rev. 7:14). Creative imagination reaches toward God, and glimpses a new heaven and new earth. The new reality has nothing to do with the present order. In fact, the one who responds to call seeks to put something more beautiful in the place of what she sees. This is where the friction and fight begin.
Martin Luther King was not killed because he had a dream. Dreamers are easily dismissed. He was killed because he sought to introduce into the political arena what he saw with his heart and mind. The same was true of Gandhi and of our Lord.
As Jesus made clear his solidarity with the poor and his vocation to engage them in a liberating process, he came into confrontation with entrenched political and religious powers.

Peter immediately took Jesus aside to protest his continuing on what was surely a collision course....
Those who say yes to the perilous vocation of implementing vision at each stage will find new resistances emerging in themselves as well as in the society. Opposition to the new is very natural and should not cause any of us to be taken by surprise. The best way to understand it in one's contemporaries is to have named and owned it in one's self. That process is also some protection against the self-righteousness that plagues too many reformers as well as the pious.
