“When it stops being culturally hard to be a follower of Jesus—when it starts to be to our cultural advantage to be Christian—historically, that has always presented a danger of compromise and corruption in the church.But when the cost of being a child of God is high, a purified church filled with love and hope shines like a city on a hill into a world dark with hate and despair.”
There is something about this reality for the institution of the church that has importance for the individuals in the church as well. There is always going to be a cost to following Jesus, and it’s for our good. If we aren’t willing to pay it, we will not experience the fullness of life in the Kingdom of God.
Today I am not going to talk about what others do to us; I am going to talk about the costly discipleship God asks us to participate in with him.
David said, “I will not give to God sacrifices that cost me nothing.” (2 Samuel 24)
Jesus told his disciples to count the cost, as if there was going to be a cost. (Luke 14)
We are called to “deny yourself, take up your cross” (Matthew 16), “die daily” (1 Corinthians 15), “present your bodies as a living sacrifice” (Romans 12), “discipline your body” (1 Corinthians 9).
In other words, Jesus calls us to die in the sense of making choices so that the things within us that are evil and destructive die, and that which brings life moves front and center.
Think of the Rich Young Ruler, so close to following Jesus except for that one thing. Jesus asked him if he would embrace poverty if asked, and it was too much. (Mark 10) There was something about his wealth and the life it brought him that was too high of a cost to pay in exchange for life in the Kingdom.
Think of the Sadducees, for whom staying cozy with Rome was far more important than taking Jesus seriously. The miracles done by Jesus and the apostles should have drawn them to hear the truth about Jesus. But if Jesus was who he said he was, the cost was higher than they were willing to pay.
The Pharisees loved purity and holiness (that’s a good thing), but it kept them from loving all their neighbors: the Samaritans, the prostitutes, the tax collector, the leper. The unclean. If following Jesus meant doing the messy work of interacting with the “unclean” up close and personal, it was too high of a cost.
This cost, this dying, is not pain for pain’s sake. It’s the fire of refinement, and refinement is hard but good. What comes out the other side is something purified and true.
“For he is like a refiner’s fire and like fullers’ soap. He will sit as a refiner and purifier of silver, and he will purify the sons of Levi and refine them like gold and silver, and they will bring offerings in righteousness to the LORD. (Malachi 2:3)
“Everyone will be salted with fire and every sacrifice will be seasoned with salt... Have salt in you and be at peace with one another." (Jesus, in Mark 9:49-50)
What shall we do with that imagery of salt and fire? I like the commentary from the Cambridge Commentary For Schools And Colleges:
“Salt, like a subtle flame, penetrates all that is corruptible and separates that which is decaying and foul, whilst it fixes and quickens that which is sound. Fire destroys that which is perishable and thereby establishes the imperishable in its purest perfection, and leads to new and more beautiful forms of being. Thus both effect a kind of transformation.
Now “everyone,” our Lord saith, “shall be salted with fire;” either (1) by his voluntary entering upon a course of self-denial and renunciation of his sins, and so submitting to the purifying fire of self--transformation; or (2) by his being involuntarily salted with the fire of… judgment (Hebrews 10:27; Hebrews 12:29).”
We are going to talk about the first way today. If we aren’t feeling the “purifying fire of self-transformation,”we have stopped short of really embracing what it means to be a follower of Jesus, and this stoppage will take from us the joy of bringing offerings of righteousness to the Lord.
Good news! The Bible shows us what that salt and fire look like, as well as how to apply it. There are ways to purposefully embrace the purifying costliness of our faith for the sake of transformation. Let’s start with an example, then move to principles.
When Paul talked about all the different groups to whom he took the gospel, he noted:
19 For since I am free from all I can make myself a slave to all, in order to gain even more people…I have become all things to all people, so that by all means I may save some… I do all these things because of the gospel, so that I can be a participant in it.
He then used an Olympic racing analogy to describe how hard this was:
Each competitor (in a race) must exercise self-control in everything… So I do not run uncertainly or box like one who hits only air. Instead I subdue my body and make it my slave, so that after preaching to others I myself will not be disqualified. (1 Corinthians 9)
It must have been hard work to get to know others so well in order to “speak their language.” It must have meant surrendering his preferences for how to share the Gospel in light of the best way they could understand the gospel. He had to live with integrity so as to not poison his words. And he did all this so that he could participate in the gospel. In 1 Corinthians 10 he notes,
“I have the right to do anything,” you say—but not everything is beneficial. “I have the right to do anything”—but not everything is constructive. No one should seek their own good, but the good of others.”
Partnering with what God is doing in the world is going to require, work, wisdom, self-control, and self-sacrificial relationships so we can participate in the gospel. We will have to get salted with that purifying fire of transformation. Here are some ideas.
1. Salty Generosity
Jesus was poured out for us; what does it look like to pour out our lives for others? A very practical way is with our resources.
Remember this: Whoever sows sparingly will also reap sparingly, and whoever sows generously will also reap generously. Each of you should give what you have decided in your heart to give, not reluctantly or under compulsion, for God loves a cheerful giver.
And God is able to bless you abundantly, so that in all things at all times, having all that you need, you will abound in every good work. As it is written: “They have freely scattered their gifts to the poor; their righteousness endures forever.”
Now he who supplies seed to the sower and bread for food will also supply and increase your store of seed and will enlarge the harvest of your righteousness. You will be enriched in every way so that you can be generous on every occasion. (2 Corinthians 9)
Give money, time, a listening ear, a car ride – whatever your resource is - for the sake of others. Help those who can’t return the favor. Let them borrow stuff you like. Make it uncomfortable for yourself.
The story is told of the preacher who was invited to preach at a church as part of a fundraising drive for repairing several churches in a parish. One attendee told him, “I could pay to fix one of those churches and not even feel it.” The preacher responded, “Why don’t you fix two and feel it?”
What does it look like to give from whatever provision God has given us until we feel it? And in that uncomfortable space, God does work as we will need to trust on His storehouse of provision.
2. Salty Hospitality
“Love must be sincere. Hate what is evil; cling to what is good. Be devoted to one another in love. Honor one another above yourselves. Never be lacking in zeal, but keep your spiritual fervor, serving the Lord. Be joyful in hope, patient in affliction, faithful in prayer. Share with the Lord’s people who are in need. Practice hospitality. (Romans 12)
This could be a cousin to the point I just made. Be practically hospitable by giving people a place at the table in your life or in your home. The table of Jesus should always have an extra seat.
But right now I am thinking about the hospitality of our head and heart. It’s the idea that we give the benefit of the doubt to people; we ascribe the best intentions to them until we are proven wrong.
Someone at church doesn’t talk to you one Sunday. You don’t know why. Assume good in them and not ill. It might be really hard to deal with the anxiety or fear you have; that’s a great opportunity to give it to Jesus.
You got cut off in that roundabout? Pray that the person driving is okay. Who knows; they may have a family emergency. They might have just gotten terrible news and were distracted. Pray for them.
There is a social media post, and it really gets under your skin. You want to feel the salt of purification? Ascribe the best of intentions to the poster. If you are going to try to read between the lines, write the best narrative you can. If you wonder what the attitude of their heart is, give them the grace that you want others to show you when they are confused.
It’s easy to stew in our own assumptions and judgments, and for most of us, that stew is toxic. When we do the work of cooking with ingredients of generosity, kindness, and hope, it’s a much better meal.
3. Salty Discomfort
Fasting from food is a classic tradition. It’s a way of taking control of our body’s needs. Maybe think of fasting as challenging our bodily urges or earthly desires and focusing on Jesus to bring us peace.
Some people do digital fasting: intentionally go without screens, social media, or streaming to make space for prayer and silence. Maybe it is fasting from instant gratification – waiting for your paycheck to get something you want instead of putting it on a card.
Fasting is not punishment; it’s practice. It trains us to say ‘no’ to lesser things so we can say ‘yes’ to Jesus. Discomfort for Christ now is preparation for faithfulness when we hit even harder times in life.
4. Salty Service
“Do nothing out of selfish ambition or vain conceit. Rather, in humility value others above yourselves, not looking to your own interests but each of you to the interests of the others.” (Philippians 2)
“Do not be proud, but be willing to associate with the hunble. Do not be conceited.” (Romans 12)
Go regularly into places where you’re not in control or where your social status or reputation doesn’t matter (food banks, prisons, nursing homes, refugee centers, homeless shelters[1]). Commit to relationships with people who can’t “give back” - the poor, the lonely, the marginalized, the overlooked. Maybe it is short-term or long-term service in a context that stretches your cultural or emotional comfort. Maybe it’s local mission in hard neighborhoods or to groups that make you uncomfortable.
It’s joining Jesus in the margins. If we want to join Jesus in what he is doing today, we will often find the most tangible evidence where the need is greatest. God offers some transformation in those spaces as we “become all things to all people” because of the gospel, so we can participate in it.
5. Salty Relationships (repentance and forgiveness)
“Therefore, as God’s chosen people, holy and dearly loved, clothe yourselves with compassion, kindness, humility, gentleness and patience. Bear with each other and forgive one another if any of you has a grievance against someone. Forgive as the Lord forgave you. And over all these virtues put on love, which binds them all together in perfect unity.” (Colossians 3)
This will require honesty. Confess sin openly to trusted believers. Let them love you, correct you, encourage you, or lead you. Be humbled and lifted up.
Don’t hide from people you have wronged. Move toward them. Humbly. Honestly. Just say, “I’m sorry,” without the need for padding. Commit to not repeating whatever it was that hurt them. Do what is in your power to do for reconciliation.
Don’t reject people who offer you their repentance. Forgive them. Refuse to hold a grudge or nurse bitterness. We will talk more next week about the dynamics of forgiveness, but for today, remember that Jesus calls us to forgive.
Refuse to retaliate. Choose blessing over cursing. Pray for the people you are stewing over in your mind – not imprecatory prayers, but prayers for God to do good, healing work in their lives for their good and His glory.
6. Salty Witness
“As for us, we cannot help speaking about what we have seen and heard.” (Acts 4)
Live the gospel all the time: that will pave the way for speaking the gospel.
Don’t be ashamed of the gospel even when it is uncomfortable. As much as is possible, live at peace with people, but don’t be afraid to own your faith. When people are talking about life, talk unashamedly about the rhythms of your faith in your life. ‘How can we not speak of what we have seen and heard?’”
Some spaces are meant for listening. Sometimes, the best thing we can do is offer a faithful presence that (hopefully) feels a lot like Jesus. Other times, the Holy Spirit is going to nudge us. Share the gospel when the Holy Spirit tells you it’s time, even if it is awkward or risky socially. Part of being salted is being patient when we want to barge in; the other is being responsive even if we are nervous.
7. Salty Sexuality
“It is God’s will that you should be sanctified: that you should avoid sexual immorality; that each of you should learn to control your own body in a way that is holy and honorable, not in passionate lust like the pagans, who do not know God; and that in this matter no one should wrong or take advantage of a brother or sister.” (1 Thessalonians 4)
Staying within God’s boundaries in our actions and our hearts is going to test us. It’s…
surrendering our sexual desires to the lordship and boundaries of Christ
treating others with honor and thinking of them with honor
building their dignity in our minds rather than fantasizing about them
refusing to reduce people to objects of gratification, but refocusing on them as imago dei.
refusing to take advantage of the bodies of others, but rather insisting that they all leave our presence having felt valued, not used.
I read a definition of chastity that talked about “directing all sexual emotions towards the holy dignity of the person.” If you let that fire salt you, the ‘you’ that emerges will be safe, honorable and holy (set apart from the world) in a beautiful way.
8. Salty Communication
One of our greatest areas for the potential work of God’s purifying fire to do its salty work is in the area of our words.
Do not let any unwholesome talk come out of your mouths, but only what is helpful for building others up according to their needs, that it may benefit those who listen. (Ephesians 4)
[The tongue] is a restless evil, full of deadly poison. With the tongue we praise our Lord and Father, and with it we curse human beings, who have been made in God’s likeness. Out of the same mouth come praise and cursing. My brothers and sisters, this should not be. (James 3)
If we want to be uncomfortable, tested, challenged, made to explore our hearts, surrender our opinions to God, work on self-control, and practice hospitable thoughts for others, this is a really great area of life for that.
There are things we must say as Christians that are necessary (truth, the gospel). There are things we can’t say if we want to follow Jesus well (slander, gossip, and lies). Then, Paul said there were things that were permissible but not beneficial or constructive.
Every word we speak is either building a bridge or burning one. If Jesus is Lord of our hearts, he must also be Lord of our tongues. If we want to get refined by a fire that will burn us into maturity, this is a really, really, really good one.
9. Salty Disciplines
“People do not drift toward holiness.” (D.A. Carson)
This is #1-#8. Spiritual disciplines will do a salty work in us. Let me add some classics.
It’s early morning prayer when you’d rather sleep, or praying instead of listening to music while you are driving. It’s studying Scripture when your mind wants to be scrolling. It’s embracing silence and solitude to talk with Jesus and appreciate God’s creation when you want noise and distraction.
Spiritual disciplines are not hoops to jump through—they’re habits that shape who we are becoming. Discipline is the training ground where desire for Christ becomes delight in Christ.
* * * * *
Yes, following Jesus costs us something. We need to be salted with the refiner’s fire. But the refining is never for our destruction; it’s for the destruction of that which is sinful in us, and that’s a good thing.
Jesus promised that those who lose their life for His sake will find it. That means that on the other side of the cost is the reward of a life marked by peace, joy, and love that this world cannot take away. The abundant life of the Kingdom is not only good for us—it overflows to bless our families, our neighbors, and even our enemies.
When we embrace costly Christianity, we become a living testimony to a watching world that Jesus is real, that His Spirit transforms, and that His Kingdom is breaking in even now.
