The disciples had just witnessed something extraordinary. Peter had declared Jesus as the Christ. Three of them had seen Jesus transfigured in glory on a mountaintop. The Kingdom of God was breaking into their reality in powerful ways. But instead of responding with humility and wonder, they found themselves arguing about who would be greatest in this coming Kingdom.

Sound familiar? We might not phrase it quite so bluntly, but the same impulse lives in us. We jockey for position, compare ourselves to others, and secretly wonder where we rank in God’s economy. We treat the Kingdom like a corporation with a ladder to climb rather than a family we’re born into.

Jesus responds to this posturing with a stunning visual. He places a child in the middle of these grown men and tells them something that would have shocked His first-century audience: “Unless you change and become like little children, you will never enter the kingdom of heaven.”

The Foundation: Becoming Like Children

The Kingdom isn’t an organization you join through achievement. It’s a family you enter through adoption. The generals and advisors in a royal court must earn their place through skill and accomplishment. But the King’s child? They have a seat at the table not because of what they’ve done, but because of whose they are.

This is the essence of Christianity. We don’t achieve a position; we accept an identity. We stop trying to be employees of the Kingdom and start resting in being children of the King.

Have you made this turn? Have you stopped trying to cover your sins with your own achievements and run to the Father with the empty hands of a child? This conversion—this fundamental change of direction—is where Kingdom life begins.

A Father’s Fierce Protection

Once we understand that we’re all children in God’s family, the rest of Matthew 18 unfolds with beautiful logic. Jesus uses language that should make us pause: “If anyone causes one of these little ones who believe in me to stumble, it would be better for them to have a large millstone hung around their neck and to be drowned in the depths of the sea.”

Why such severe imagery? Because a good father watches out for his children. You can offend a parent all day, but harm their child and you’ll see another side of them emerge. This is the zealous affection the Father has for His children.

This leads to our first responsibility in the church community: we protect one another.

But notice the contrast in Jesus’s teaching. When it comes to dealing with someone else’s sin, He prescribes a careful, grace-filled, step-by-step process. But when addressing our own sin? “Cut it off. Gouge it out. Throw it away.” We want to flip this, don’t we? We want to be harsh judges of everyone else while seeking nuance and grace for ourselves.

Jesus makes it clear: our primary responsibility to the family is our own discipleship. We protect one another by being radically committed to overcoming our own sin.

The Pursuit of the One

Jesus tells a parable about a shepherd who leaves ninety-nine sheep to find the one that wandered. Let this truth sink in: the Father cares for you—not just the church in general, but you specifically. If you wander, He pursues. He’s the Good Shepherd who leaves the safety of the fold to hunt you down in the thicket.

If this is how the Father loves His children, this is how we must love one another. We don’t just let people drift away. We don’t say, “Well, I haven’t seen them in weeks, I guess they’re busy.” No, we go after the one.

The Hard Work of Restoration

This pursuit leads directly to practical application. How do we go after the wandering sheep? Jesus gives us a four-step process for restoration:

Step One: Private Correction. Go to the person privately, just the two of you. Our tendency is the opposite—we tell everyone except the person. That’s gossip, and it’s sin. The goal is to keep the circle as small as possible. If they listen, you’ve won your brother.

Step Two: Small Group Clarification. If they don’t listen, take one or two others along. This isn’t about ganging up; it’s about establishing truth and providing witnesses who can verify both the sin and the response.

Step Three: Church Admonition. If they refuse to listen, tell it to the church. The circle expands so the body can pray and participate in calling the person back. It’s a final, massive plea of grace.

Step Four: Church Excommunication. If they refuse the church, treat them as an unbeliever. This doesn’t mean cruelty—we love unbelievers and evangelize them—but they have a different standing in the community.

This is church discipline, and it’s an act of love. A doctor who sees cancer growing but doesn’t mention it to avoid upsetting the patient isn’t loving—that’s malpractice. Love confronts the disease to save the life.

The Mathematics of Forgiveness

Peter thought he was being generous when he asked if forgiving someone seven times was enough. The rabbis taught three times was sufficient. Jesus responds: “Not seven times, but seventy times seven.” In other words, stop counting.

Then Jesus tells a parable that should shake us to our core. A servant owes his king ten thousand talents of gold. It would take three million years of labor to repay. The debt is impossible. Yet the king, moved with compassion, wipes it clean.

That same servant then finds someone who owes him a hundred denarii—maybe ten or fifteen thousand dollars. Real money, but compared to 150 billion? A rounding error. Yet he grabs the man by the throat and has him thrown in prison.

The point pierces: we are the servant with the unpayable debt. Our sin against God carries no price tag we could ever afford. And Christ, at the cost of His own life, paid it all.

So how can we hold a grudge? When we refuse to forgive, we’re saying, “God, I know you forgave my 150 billion dollar debt, but this person’s ten thousand dollar debt is just too big.” It’s theological insanity.

We don’t forgive because the other person deserves it. We forgive because we’ve been treated better than we deserve.

Living as Kingdom Children

This vision of Christian community is radical. It assumes committed relationships where people know each other well enough to spot sin, love each other enough to confront it, and trust each other enough to receive correction.

It requires looking honestly at our own lives. Are we causing others to stumble? Is there a conversation we’ve been avoiding? Are we harboring bitterness over some small debt while standing under the waterfall of God’s overwhelming grace?

The Father has protected us. He has pursued us when we were the one lost sheep. He has restored us. He has forgiven us an impossible debt.

May that love compel us to love one another with the same fierce protection, relentless pursuit, patient restoration, and limitless forgiveness.
