“You don't know what you're asking,” Jesus told them. “Are you able to drink the cup I'm about to drink?” “Yes, we are able to do that,” they told him.
Wake up, wake up! Get up, Jerusalem! You have drunk from the cup of the Lord's anger he handed to you. You have drained it down to the bottom of the cup, the drink that makes people stagger around.
This is what your Lord God says, your God, who defends his people's cause: Look! I have taken away from you the cup that made you stagger around. You will never again have to drink from that cup, the cup of my anger.
This is what the Lord says: If those who were not required to drink from the cup of judgment had to do so, how could you not be punished yourselves? You won't go unpunished, because you have to drink it too.
He went a little farther forward, fell facedown, and prayed. “My Father, please, if it's possible, let this cup of suffering be taken from me,” Jesus asked. “Even so, may it not be what I want but what you want.”
Similarly the Spirit helps us in our weakness. We don't know how to speak with God, but the Spirit himself intercedes with and through us by groans that can't be put into words.
