Mark 10:39

‘And they said to him, “We are able”.'

In their reply they had no idea what He was talking about. Perhaps they did naively think in terms of the King's cup and social graces, or perhaps they acknowledged that although there may be dangers ahead when Jesus as Messiah finally sought to establish His rule, they would be well able to face the opposition bravely, and if necessary die nobly for the cause. But what they had no idea of was the humiliation, the suffering, the degradation, even the slow martyrdom by exquisite torture, of which He was speaking.
