That's the shortest verse in the Bible, and in many ways, the most astonishing. Think of it. Christians worship a God who cries. I don't think any other religion in the history of the world has done that. The Roman world must've been dumbstruck by such a notion; the biggest going philosophy of the time was Stoicism, which maintained among other things, that the wise man is immune to strong emotions. "Be in control of your emotions, or your emotions are in control of you," sort of thing, and here's Jesus. Weeping. God, philosophers have argued since time immemorial, would be above suffering, impassible: to have passions meant one was subject to outside forces. When people talk about the Passion of Christ, they aren't talking about his love, but his suffering. Outside forces worked him around like a rag doll in a tornado.
It is an odd thing, but to a Christian the concept of God is not complete unless God has known all things, experienced all things, felt all things - including the shedding of futile tears.
Today we celebrate the Resurrection which is a pretty remarkable event, but lots of religions have worshipped gods that died and came back to life: The Golden Bough is chock full of such examples. But no religion besides Christianity ever had a god that wept.
