The main thing to grasp about our current situation in the world is that it is essentially unprecedented.
Is that so hard to understand?
OK - there are always similarities to be drawn between any two complex things - but the current situation in unprecedented in so many ways (spiritually especially, but even more obviously the physical-material) - that Now needs to be regarded as essentially different from anything that ever happened at any point in history.
Of course, this entails that we cannot predict what will happen - except in broad outline and without a clear timescale - but surely that is obvious anyway?
What we ought to be doing as Christians is to try (it's difficult!) to detach from large-scale and abstract speculation (which is the level at which evil is operating) - which implicitly encourages us as individuals to fit-in with some worldly-grouping...
And instead focus on the personal, spiritual, experiential perspective.
Which is also, potentially, the perspective of hope.
