“Take a lesson from the fig tree. From the moment you notice its buds form, the merest hint of green, you know summer’s just around the corner. So it is with you: When you see all these things, you’ll know he’s at the door. Don’t take this lightly. I’m not just saying this for some future generation, but for all of you. This age continues until all these things take place. Sky and earth will wear out; my words won’t wear out.
