What does Mark 10:40 mean?
Matthew notes that the positions of honor which James and John ask for are already designated by God the Father (Matthew 20:23). We have seen how He chose Samson (Judges 13:2–5) and John the Baptist (Luke 1:5–17) before they were born. We know that He chooses who will be saved (Ephesians 1:4). Jesus specifically chose the Twelve to be His disciples (Mark 3:13–19) and Paul to be an apostle (Acts 9:1–19). The Holy Spirit even chooses who will have what gifts to serve the church (Ephesians 4:11–12; 1 Corinthians 12:7). So, as God looks out over all human history with one glance, it's evident that He works directly in that history, and invites us to join His work in different ways. We need to focus on listening for His call in our own lives and making sure we answer "yes."James and John assume that their closeness to Jesus combined with their willingness to sacrifice much and work hard for His kingdom will earn them high positions. This is the way of the world, including the province of Israel. In the church age, honor, importance, and authority do not necessarily go together (1 Corinthians 12:22–25). Leaders are servants (John 13:3–16). Unlike many of the kings of Israel and Judah, only those who first honor their wives and lead their families well may lead the church (1 Timothy 3:2–5).
Soon, however, there will be two men chosen to be at Jesus' right and left hand. But they are men the disciples could never have imagined: two thieves (Mark 15:27). They will literally pick up their crosses and be crucified with Christ, but this will not guarantee them positions in heaven. Great suffering does not earn us salvation, just as it does not earn us positions of authority in the church. Although both thieves suffered, the only one to see paradise was the one who recognized he was as powerless as a child (Mark 10:15) and placed his trust in Jesus (Luke 23:39–43).
Mark 10:35–45 describes the arrogant request of James and John to have positions of power and authority in Jesus' coming kingdom. This comes after learning that Jesus values the powerless like women and children (Mark 10:1–16), that those with earthly power and wealth can have a hard time following God because they can tend to value their possessions more (Mark 10:17–22), and that part of Jesus' plan for His kingdom is to die a horrible death (Mark 10:32–34). Neither Luke nor John record this account, but Matthew adds that James and John's mother is involved in the request (Matthew 20:20–28).
In this passage, Jesus again confronts the Pharisees by clarifying God's views on marriage and divorce. He reminds the disciples not to dismiss the spiritual perspective of children. This chapter also records Jesus' encounter with the rich young ruler, who becomes an object lesson in why wealth makes it hard for people to rely on God. After this, Jesus deftly sets aside an arrogant request from James and John, and again predicts His impending death. Just prior to the triumphal entry of chapter 11, Jesus is sought out by Bartimaeus, whom He heals of blindness.
