Today BibleWorm reads from the Markan apocalypse, Mark 13:1-8 and 24-37 - a vision of the thorough undoing of the world as we have come to know it. The most grand of buildings will fall. The weather patterns that sustain our food and water will falter. Even heaven and earth will not endure.   My persistent question reading these texts was – for better and for worse, is - what do people do when they think the world is going to end? How can this knowledge root us in the teachings of the Torah, or the word of Jesus, without prompting us to shrink back from a world that still needs us?
