An astounding summary of a certain worldview given in Miroslav Volf's Free of Charge. This is not his worldview, and he doesn't leave it at this, but this description really got me with the profound sadness of the human condition if Christ has not died and come back to life:
I do wake up sometimes in the middle of the night, surrounded by the darkness, and think, "We're all a bunch of egoists, some more pleasant than others, some smart enough to be short-term altruists, but we're just stuffing ourselves and puffing ourselves up. Maybe no love has created us, no love dwells in our deceitful hearts, and no world of love will ever be given to us. We come out of inchoate darkness, and we return to inchoate darkness, and in the brief period we are alive, we are black holes of self-absorption."
