In this last verse Jesus speaks of “the cup the Father gives me.” It is one of two cups spoken of often in Scripture. One is the cup of salvation. The other cup is the cup of God’s wrath or tribulation, which is referred to here. Two cups: the cup of salvation and the cup of God’s wrath. Every person who has ever lived shall drink from one of them. But those who drink of the cup of salvation by God’s grace will drink of it only because Jesus drank the cup of God’s wrath in their place.
