"It needs to change", we might say or embody. But the world can't change forever. Someday it must reach a really good state.
Complacency is a bad in itself. Being complacent is being closed on a deep level. So how can we stay open?
Should we love the world? That may mean that we love the status quo. Both the good and the bad come from the status quo. Sometimes you can separate the bad from the good, but the default assumption is that it's a package deal. A system is one thing, is what it is with all its parts. So if we love any one existing thing, maybe we have to keep the status quo. If we love (or "love") any one thing enough, we can't risk changing the system, at the risk of losing that thing. Does this mean that people who want to see change can't love? Can't trust?
Perhaps this is why the world is so messed up (in part). People can't sustain "it needs to change". They crave to love, can't refrain from loving, though refraining might make things better in the long run. Maybe to make things better, you need to hate some specific thing. Hate evil -- but then, hate can be evil, and is definitely unbearable in the end, a maintaining of lack of trust. So the hate that brings about good comes intermittently. And refraining from love is hard to sustain as well.
I think it's good to say "this world is not all there is", which is akin to "this world as it is not as it should be". Both say "the world, everything that adds up to my own satisfactions, my own wealth, is insufficient."
God exists outside this world. The love we have for God is not the love we have for the world, the love for all the gifts that give us satisfaction and security. We can love and trust God, and thus take weight off of seeing the world as it is as a good thing, which we might feel is necessary to keep from cutting ourselves off from loving and trusting as activities that are good for us.
Hate and alienation are akin. We are sometimes alien in ways that are natural and familiar to us. But God's alienness is not our alienness. God is a father (a familiar image), but also an alien. To love an alien as its child requires that you become an alien yourself.
