The Giant in the Mirror: Why the Enemy Is Closer Than You Think
What if the giant you've been fighting isn't the obstacle in front of you — but the one living inside you?
That's the uncomfortable truth I sat with as I prepared this week's message. We're in week three of our Slaying Giants series, and I have to be honest: this one hit differently. Because this giant doesn't confront us from the outside. This one inhabits us.
When the Battle Goes Wrong
We've been following Israel as they step into the Promised Land. Week one, they faced the Jordan River at flood stage. Week two, Jericho — with its impenetrable walls. Both times, God showed up. Both times, the giants fell.
So when Israel marched toward their next target — a tiny village called Ai — the scouting report was almost dismissive. "Don't send everyone. Two or three thousand will be enough. They are few." This one should have been easy.
It wasn't.
Thirty-six men died. Israel's army ran home in defeat. And Joshua chapter 7 records this devastating detail: "The hearts of the people melted and became as water."
That's the same language Rahab used to describe how the people of Jericho felt when they heard Israel was coming. Now Israel was the terrified one. Something had changed — but what?
The Call Is Coming From Inside the House
Joshua did what any of us would do. He looked outward. He fell before God and essentially asked, "What went wrong out there?"
And God redirected him: "Israel has sinned."
The problem wasn't Ai. The problem was in the camp.
God's words in Joshua 7:11-12 are striking: "Israel has sinned; they have transgressed my covenant that I commanded them; they have taken some of the devoted things; they have stolen and lied and put them among their own belongings. Therefore the people of Israel cannot stand before their enemies."
Before the walls of Jericho fell, God had been explicit: the silver, the gold, the vessels of bronze and iron — those belong to the Lord. They were off limits. But someone decided that what God said didn't apply to them.
That someone was a man named Achan. And when he finally confessed, he gave us one of the most honest and heartbreaking sequences in all of Scripture: "I saw… I coveted… I took… I hid."
A Pattern as Old as the Garden
Here's what stopped me cold in my study this week. Achan didn't invent this pattern. He inherited it.
Go back to Genesis 3. Eve saw that the tree was good for food. She desired it. She took it. And when God came, they hid.
Jump to 2 Samuel 11. King David looked from his balcony and saw Bathsheba. He desired her. He sent for her and took her. And the rest of the chapter is a desperate, increasingly destructive attempt to hide what he had done.
Saw. Desired. Took. Hid. Same pattern, different tent.And then the Apostle Paul makes it uncomfortably personal in Romans 7:19: "For I do not do the good I want, but the evil I do not want is what I keep on doing."
Paul isn't pointing at Achan's tent. He's describing the war inside himself. And honestly? When I read that, I felt the investigation getting awfully close to home.
The Giant Is Us
Here's the hard truth I had to preach — and live with: the giant isn't out there. The giant is us.
The giant of "us" is the desire in me to be lord of me. I want to decide what is good. I want to determine what rules apply to me. I want the throne.
James 1:14-15 explains the whole anatomy of it: "Each person is tempted when he is lured and enticed by his own desire. Then desire when it has conceived gives birth to sin, and sin when it is fully grown brings forth death."
The object of temptation may be outside of us — the cloak, the fruit, the gold — but the hook on the outside is catching something on the inside. And the sin we bury doesn't stay the same size we buried it.
So if I am the giant, how do I defeat me?
The Answer Is Jesus
Paul cries out in Romans 7:24-25: "Wretched man that I am! Who will deliver me from this body of death? Thanks be to God through Jesus Christ our Lord!"
Notice the question. Paul doesn't ask how to fix himself. He asks who will deliver him. Because if I am the giant, I cannot defeat me with more of me.
The answer to the giant of us is not trying harder to be better. It's Jesus.
As Paul writes in Galatians 2:20: "I have been crucified with Christ. It is no longer I who live, but Christ who lives in me."
All morning we chase the word I — I saw, I desired, I took, I hid, I want the throne. And the Gospel answers: it is no longer I, but Christ.
Here's how you defeat the giant of us: with a cross and an empty tomb.
And here's the word I want to leave you with from 1 John 1:9: "If we confess our sins, he is faithful and just to forgive us our sins and to cleanse us from all unrighteousness."
You don't have to hide from a Savior who already knows. You don't have to protect a sin that Jesus already died for. Stop protecting what's killing you.
What's Your Nail?
I wonder how many of us are trying to do that with Jesus. You can have everything, Lord — just not this. This nail is mine.
Achan had one hole underneath his tent. One place he decided was his. And it cost him everything.
What's your nail? What's the one place you keep telling Jesus, "Not this — this is mine"?
This week, I want to encourage you to do two things. First, let God examine you. Ask Him honestly: Is there something I'm hiding that's keeping me from being on mission with You? Second, think of one person in your life who needs to hear about Jesus — a neighbor, a coworker, a friend — and begin praying for them by name.
The giant of us is not supposed to have the throne anymore. Jesus is. And because of Him, sin doesn't get the final word.
