Greatness, sin, and salt in Jesus' kingdom

9:30 They went out from there and passed through Galilee. But Jesus did not want anyone to know, 9:31 for he was teaching his disciples and telling them, "The Son of Man will be betrayed into the hands of men. They will kill him, and after three days he will rise." 9:32 But they did not understand this statement and were afraid to ask him. 9:33 Then they came to Capernaum. After Jesus was inside the house he asked them, "What were you discussing on the way?" 9:34 But they were silent, for on the way they had argued with one another about who was the greatest. 9:35 After he sat down, he called the twelve and said to them, "If anyone wants to be first, he must be last of all and servant of all." 9:36 He took a little child and had him stand among them. Taking him in his arms, he said to them, 9:37 "Whoever welcomes one of these little children in my name welcomes me, and whoever welcomes me does not welcome me but the one who sent me." 9:38 John said to him, "Teacher, we saw someone casting out demons in your name, and we tried to stop him because he was not following us." 9:39 But Jesus said, "Do not stop him, because no one who does a miracle in my name will be able soon afterward to say anything bad about me. 9:40 For whoever is not against us is for us. 9:41 For I tell you the truth, whoever gives you a cup of water because you bear Christ's name will never lose his reward. 9:42 "If anyone causes one of these little ones who believe in me to sin, it would be better for him to have a huge millstone tied around his neck and to be thrown into the sea. 9:43 If your hand causes you to sin, cut it off! It is better for you to enter into life crippled than to have two hands and go into hell, to the unquenchable fire. 9:45 If your foot causes you to sin, cut it off! It is better to enter life lame than to have two feet and be thrown into hell. 9:47 If your eye causes you to sin, tear it out! It is better to enter into the kingdom of God with one eye than to have two eyes and be thrown into hell, 9:48 where their worm never dies and the fire is never quenched. 9:49 Everyone will be salted with fire. 9:50 Salt is good, but if it loses its saltiness, how can you make it salty again? Have salt in yourselves, and be at peace with each other."

Jesus teaches his disciples that true greatness is found in humble service, welcoming the lowly, and caring for those who belong to him. He warns against causing others to sin and calls for decisive action against anything that leads a disciple into sin. The closing sayings about salt call for inward seriousness and peace with one another.

Jesus first tells his disciples again that the Son of Man will be handed over, killed, and rise after three days. They do not understand, and their confusion shows up in their argument about who is greatest. Jesus answers by reversing their idea of greatness: if anyone wants to be first, he must be last of all and servant of all.

He then places a little child among them and says that whoever welcomes such a one in his name welcomes him, and also the One who sent him. The point is not mainly the child's innocence. The point is that disciples must receive the lowly and insignificant as people who belong to Jesus.

When John reports that they tried to stop a man casting out demons in Jesus' name because he was not following them, Jesus corrects their possessiveness. Genuine work done in his name should not be blocked simply because it comes from outside their group. Even a cup of water given because someone bears Christ's name will not go unrewarded.

Jesus then gives a severe warning. If anyone causes one of these little ones who believe in him to sin, it would be better to face terrible judgment. He then speaks of cutting off a hand, foot, or eye if it causes sin. This is vivid and hyperbolic language. It is not a command for literal self-harm. It means disciples must deal decisively with whatever leads them into sin, even if that costs them deeply.

He contrasts the loss of a body part with the loss of life and the kingdom of God. The warning is serious because hell is real judgment. The final sayings about salt gather the whole unit together. Jesus calls his followers to have salt in themselves and to be at peace with one another. That means inward purity, covenant seriousness, and humble unity instead of rivalry.

• Jesus' prediction of betrayal, death, and resurrection frames the whole passage.
• Greatness in Jesus' kingdom is measured by service, not status.
• Receiving the lowly in Jesus' name is treated as receiving Jesus and the Father who sent him.
• Jesus rebukes jealous control over who may act in his name.
• Small acts of care done because someone belongs to Christ are seen and rewarded by God.
• Causing vulnerable believers to sin is a grave offense.
• The commands about cutting off hand, foot, or eye are hyperbolic, but they demand decisive action against sin.
• The passage sets eternal life and the kingdom against final judgment.
• The closing salt sayings call for inward seriousness and peace in the community.

• Do not read the child as mainly a symbol of innocence; the point is low status and smallness.
• Do not use 'whoever is not against us is for us' as a blanket approval of every ministry claim; the issue is sectarian jealousy.
• Do not reduce the warnings about hell to temporary consequences only; Jesus speaks with final-stakes seriousness.
• Do not take the body-part sayings literally as commands for self-harm; they are severe hyperbole calling for decisive removal of sin's occasions.
• The saying about being salted with fire is compressed and debated, so it should be handled carefully.

Jesus' path to the cross becomes the pattern for discipleship. He moves toward suffering, but he teaches that the kingdom advances through humble service, lowly welcome, mercy toward others in his name, and holiness that resists sin. The passage joins Jesus' redemptive suffering with the disciple's call to follow him in costly obedience and peace.

Believers should measure greatness by service, not by recognition. They should welcome weak and overlooked people, and they should not become jealous when others truly honor Jesus. They must also take sin seriously, remove what leads them into it, and pursue peace with one another through humility.
