Our greatest glory is Jesus as the Propitiation of God's Wrath for our sin

Read this passage (again for the umteenth time!) and do it in Greek if that makes you read more slowly:

35 And James and John, the sons of Zebedee, came up to him and said to him, “Teacher, we want you to do for us whatever we ask of you.” 36 And he said to them, “What do you want me to do for you?” 37 And they said to him, “Grant us to sit, one at your right hand and one at your left, in your glory.” 38 Jesus said to them, “You do not know what you are asking. Are you able to drink the cup that I drink, or to be baptized with the baptism with which I am baptized?” 39 And they said to him, “We are able.” And Jesus said to them, “The cup that I drink you will drink, and with the baptism with which I am baptized, you will be baptized, 40 but to sit at my right hand or at my left is not mine to grant, but it is for those for whom it has been prepared.” 41 And when the ten heard it, they began to be indignant at James and John. 42 And Jesus called them to him and said to them, “You know that those who are considered rulers of the Gentiles lord it over them, and their great ones exercise authority over them. 43 But it shall not be so among you. But whoever would be great among you must be your servant, 4 44 and whoever would be first among you must be slave 5 of all. 45 For even the Son of Man came not to be served but to serve, and to give his life as a ransom for many.”

(Mark 10:35-45 ESV)

The cup Jesus speaks of is the wrath of God and Romans 6:3 makes it clear that we who are justified by Christ’s death are united with Christ in the baptism He was baptized with. So instead of longing for wealth or prestige or power, what He points His disciples toward here is to envision one central act (identified by the cup and baptism He speaks of) as the ultimate display of glory: His death as the wrath-bearing propitiation for the sins we committed. Instead of emulating the rulers of the nations, Jesus calls us to emulate His values and example: that He loved the Father’s glory so exceedingly that nothing could compare with the allure of suffering voluntarily in obedience to His Father for the sake of the exaltation of the glory of God’s justice and holiness. I pray that God will thus make His own glory my greatest delight.
