Jamieson-Fausset-Brown Bible Commentary

And they said unto him, We can--Here we see them owning their mother's petition for them as their own; and doubtless they were perfectly sincere in professing their willingness to follow their Master to any suffering He might have to endure. As for James, he was the first of the apostles who was honored, and showed himself able to be baptized with his Master's baptism of blood (Act 12:1-2); while John, after going through all the persecutions to which the infant Church was exposed from the Jews, and sharing in the struggles and sufferings occasioned by the first triumphs of the Gospel among the Gentiles, lived to be the victim, after all the rest had got to glory, of a bitter persecution in the evening of his days, for the word of God and for the testimony of Jesus Christ. Yes, they were dear believers and blessed men, in spite of this unworthy ambition, and their Lord knew it; and perhaps the foresight of what they would have to pass through, and the courageous testimony He would yet receive from them, was the cause of that gentleness which we cannot but wonder at in His reproof. 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--No doubt this prediction, when their sufferings at length came upon them, cheered them with the assurance, not that they would sit on His right and left hand--for of that thought they would be heartily ashamed--but that "if they suffered with Him, they should be also glorified together."
