Charles Spurgeon Commentary Mark 10:39

"And they said unto him, We are able. And Jesus said unto them, The cup that I drink ye shall drink; and with the baptism that I am baptized withal shall ye be baptized:" — Mark 10:39 (ASV)

And Jesus said unto them, Ye shall indeed drink of the cup that I drink of; and with the baptism that I am baptized withal shall ye be baptized:

And so they were, for James was soon put to death, and John lived, the last and longest of the apostles, a life-long martyrdom for the Master's sake.

And they said unto him, We can.

They did not know what they said, but they felt that the strength of their love was such that they could share anything that had to do with Christ!

His throne! Yes, they would like to sit at the right hand of it. His cup! Yes, they can drink of it. Immersion into his suffering! Yes, they can endure that baptism.
