More and more I am recognizing that my book on cynicism (see the icon in to the right) is ultimately a pastoral exercise in applying Christian eschatology to our daily reality.
Cynicism arises from disillusionment. When the rug gets jerked form beneath our feet and we find ourselves breathless staring up at the ceiling, wondering what hit us, only to remember, oh yeah, it was REALITY that hit. Idealism cannot thrive in an ex-Eden world. But cynicism is just as untenable in a world into which Christ has come, from which He has ascended, and to which He will return.
Eschatology is why cynicism is not valid… at least not for Christians.
If there is an open hole in the ground of this earth—the empty tomb of Jesus—then something cataclysmic has taken place. The resurrection of the dead, implied in a few places in the OT (Isa 25, Dan 12, Ezek 37) and discussed more openly in the literature of Early Judaism, has been jump-started into our present sphere by the “first fruits” (1 Cor 15) of Christ’s own resurrection. The New Age to Come (this is language found in Early Judaism and throughout the NT) has lurched backward from the future into our current time, overlapping with the Present Evil Age.
In Faith Without Illusions, I cite George Eldon Ladd near the end. Here is a wonderful quote I just reread this afternoon:
Christ’s resurrection is not an isolated event; it is in fact an eschatological occurrence which has been transplanted into the midst of history. We are living already on the heavenward side of the first stage of the resurrection. This puts a whole new light on the whole human predicament. 
You can click on the About the Blog section for more on “hopeful realism,” the perspective alternative to cynicism and idealism I am calling for in the book. Ultimately, hopeful realism is both eschatological (“hopeful”—appreciating the work of God in the overlap of the Ages and anticipating Christ’s return) and cosmological (“realism”—recognizing the full brunt of fallenness that has plagued our world and our own hearts so disastrously).
The Kingdom is in our midst… and still yet to come.
