35 Then James and John, the sons of Zebedee, came to Him, saying, "Teacher, we want You to do for us whatever we ask." 36 And He said to them, "What do you want Me to do for you?" 37 They said to Him, "Grant us that we may sit, one on Your right hand and the other on Your left, in Your glory." 38 But Jesus said to them, "You do not know what you ask. Are you able to drink the cup that I drink, and be baptized with the baptism that I am baptized with?" 39 They said to Him, "We are able." So Jesus said to them, "You will indeed drink the cup that I drink, and with the baptism I am baptized with you will be baptized; 40 but to sit on My right hand and on My left is not Mine to give, but it is for those for whom it is prepared." 41 And when the ten heard it, they began to be greatly displeased with James and John.

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.
