Salt and Fire
Disciples are called to be salt—seasoned through trials and preserving the life of God’s Kingdom by embodying humility, sacrifice, and faith.
9:49 Everyone will be salted with fire.
Jesus has just called his disciples to a radical pruning— cutting off the old self to allow the new self to flourish. He then pivots his metaphor to salt and makes the strange declaration that everyone will be salted with fire. What is he saying here?
First off, salt was an uber-important staple in the ancient world. Salt was life: it kept food from spoiling in a world without refrigerators, it flavored meals that might otherwise be bland, and it was even part of offerings in the temple (Leviticus 2:13). To talk about salt was to talk about something essential to the disciples. But what is the fire all about.
In Matthew, Jesus uses this same imagery in his sermon on the mount. But there he says something that helps us understand what’s going on here. He says to his disciples and would be disciples in the crowd— you are the salt of the earth.
The role of the disciple is the role once given to Israel and is now the role of all of God’s people in the world. To preserve the image of God in the world. To live out of our created in the image of God and redeemed in Jesus new self for the sake of the world. How will the world know what God is like— they will see God through his people. That has always been the plan. God loves using flesh to preserve his image in the world.
But this preservation is not easy in a world that often rejects truth and life.
When Jesus talks about salting with fire, he’s saying something about the cost of discipleship. The disciples were not being called to an easy life of watching miracles; they were being called to endure suffering, to be purified, and in their endurance, to become a preserving presence in a world that is constantly decaying.
50 “Salt is good, but if it loses its saltiness, how can you make it salty again? Have salt among yourselves, and be at peace with each other.”
And here’s the twist of Jesus’ teaching: salt can lose its saltiness. In other words, the disciples could drift. They could return to chasing greatness, clinging to power, or protecting their own importance—and in doing so lose the very flavor of the kingdom they were meant to carry. A disciple who forgets the way of humility eventually stops looking like Jesus.
Jesus’ call, then, is not only to preach the message of the upside-down kingdom, but to embody it in their very lives. They are to be the seasoning that makes that helps the world taste the goodness of God, and the preservative that keeps the rot of despair and sin from consuming everything. “Have salt among yourselves,” Jesus says. It is as if he’s saying: don’t just talk about me—live me. Preserve the humility, the servanthood, and the smallness I’ve been calling you to.
The world doesn’t need louder religious voices nearly as much as it needs lives quietly flavored by the presence of Christ. When disciples embrace the refining fire and walk the humble road of Jesus, their lives begin to carry the unmistakable taste of the kingdom. And once you’ve tasted that kind of life, everything else suddenly feels a little bland.
