“And the LORD sold them into the hand of Jabin king of Canaan, that reigned in Hazor; the captain of whose host was Sisera, which dwelt in Harosheth of the Gentiles. And the children of Israel cried unto the LORD: for he had nine hundred chariots of iron; and twenty years he mightily oppressed the children of Israel.” ~ Judges 4:2-3

Every coach knows the runner with the small ache.

A little tightness in the shin. A twinge in the foot that fades once the warmup is over. Nothing worth mentioning. Nothing worth missing a workout over. So the runner keeps running on it, because it’s small, and small things don’t stop training.

Until one morning it isn’t small anymore.

What a week of rest could have fixed becomes a stress fracture, a walking boot, and a lost season.

Israel knew something about that.

Here is the strange part: Hazor should never have been a problem. Joshua had already burned it to the ground and killed its king (Joshua 11:10-11). The city was finished. The enemy was beaten.

But back in the opening chapter of Judges, the tribes settled for partial obedience. They left pockets of Canaanites in the land. Judah couldn’t drive out the people of the valley “because they had chariots of iron” (Judges 1:19). That was the moment to deal with it. Instead, Israel learned to live around it.

A generation or two later, the chariots are back.

Nine hundred of them.

The enemy Israel tolerated when it was manageable rebuilt the city, raised an army, and spent twenty years crushing the very people who once had it on the run.

That’s how it works. Enemies rarely show up at full strength. They show up small, and we let them stay because they seem harmless. The habit we’ve decided isn’t a big deal. The grudge we keep feeding. The compromise we promise ourselves we’ll handle later.

Small things don’t stay small. They build chariots.

Now, we need to read Judges rightly. Israel was under a conditional covenant — obey and be blessed, disobey and be sold into the hand of the enemy (Judges 2:14). That is not our arrangement. We live in “the dispensation of the grace of God” (Ephesians 3:2), and God is not handing the believer over to oppressors as covenant punishment. “There is therefore now no condemnation to them which are in Christ Jesus” (Romans 8:1).

But grace doesn’t make sin harmless.

Paul puts it plainly: “Neither give place to the devil” (Ephesians 4:27). The word for “place” there is topos — a spot, a piece of ground, room to stand. Paul isn’t warning about an invasion. He’s warning about a foothold. And footholds become strongholds when nobody deals with them. “A little leaven leaveneth the whole lump” (Galatians 5:9).

We don’t fight these things to earn God’s favor. We fight them because we already have it. The same grace that saved us is the grace that teaches us to deny ungodliness (Titus 2:11-12).

So the question isn’t whether there’s an enemy in the land. There is. There always is.

The question is how big you’re going to let it get.

Deal with the twinge. Before it becomes the fracture.

What’s one small thing you’ve been running on? What would it look like to deal with it this week — while it’s still small?
