35 Then James and John, the sons of Zebedee, came over and spoke to him. "Teacher," they said, "we want you to do us a favor." 36 "What is your request?" he asked. 37 They replied, "When you sit on your glorious throne, we want to sit in places of honor next to you, one on your right and the other on your left." 38 But Jesus said to them, "You don't know what you are asking! Are you able to drink from the bitter cup of suffering I am about to drink? Are you able to be baptized with the baptism of suffering I must be baptized with?" 39 "Oh yes," they replied, "we are able!" Then Jesus told them, "You will indeed drink from my bitter cup and be baptized with my baptism of suffering. 40 But I have no right to say who will sit on my right or my left. God has prepared those places for the ones he has chosen."

Commentary on Mark 10:32-45
(Read Mark 10:32-45)
Christ's going on with his undertaking for the salvation of mankind, was, is, and will be, the wonder of all his disciples. Worldly honour is a glittering thing, with which the eyes of Christ's own disciples have many times been dazzled. Our care must be, that we may have wisdom and grace to know how to suffer with him; and we may trust him to provide what the degrees of our glory shall be. Christ shows them that dominion was generally abused in the world. If Jesus would gratify all our desires, it would soon appear that we desire fame or authority, and are unwilling to taste of his cup, or to have his baptism; and should often be ruined by having our prayers answered. But he loves us, and will only give his people what is good for them.
