Reassurance That the Drink Isn't Poisoned

What do you do to reassure someone that the drink you're offering contains no poison? You drink it yourself first, in their presence. This is what God did for humanity. God drank from the bitter cup of suffering in the Passion. If, before our eyes, God himself chose to drink it, human suffering cannot be a cup of poison; it must be more than just negativity, loss, and absurdity. At the bottom of the cup, there must be a pearl. We know the name of that pearl: resurrection!

This is an interesting answer to the question of human suffering.
