“Watch, stand fast in the faith, be brave, be strong.” – 1 Cor. 16:13, NKJV

A professional soldier will hold a line that a mercenary would abandon.

Ask him why, and he seldom talks about himself.

He speaks of the flag, the people behind him, a cause that was here before he enlisted and will remain after he is gone.

His courage is borrowed from something larger than his own blood.

Paul understood this when he wrote the above verse: “Watch, stand fast in the faith, be brave, be strong.”

Read it as a drill sergeant would.

Four short commands: Keep watch at your post.

Hold your ground.

Show courage.

Be strong.

The picture is a garrison of soldiers standing shoulder to shoulder, facing an enemy.

Corinth needed that military charge.

It was a prosperous port city, crowded with rival philosophies and easy morals, where blending in was the path of least resistance.

Your world is not so different.

It is dangerous precisely because it is comfortable, and it keeps inviting you to lower your guard.

Soldiers seldom fall to the enemy they see charging.

They fall to the one they stopped watching for.

Now notice what the command asks of the weary fighter.

When life wears us down, most of us clench our teeth and dig deeper, as though strength were a private reserve we only need to tap harder.

Paul’s grammar says otherwise.

“Be strong” is passive.

Literally, it means be strengthened.

Paul is not telling exhausted people to manufacture endurance.

Walk into your workplace, your home, your school and your neighbourhood without the panic of a man guarding himself.

He is telling them to let themselves be made strong by Another.

A soldier who must produce his own strength will break on the first long night.

This is how Paul speaks elsewhere.

He prays that God would grant strength “through his Spirit in the inner man” (Ephesians 3:16), and he commands, “Be strong in the Lord and in the power of His might” (Ephesians 6:10).

The power is supplied. Our part is to receive it and stay at our post.

Why trust the supply line?

Look at the chapter just before.

In 1 Corinthians 15, the apostle says the resurrection broke the grip of death, the last enemy.

Now Christ reigns, and every enemy is being put under His feet.

We are not a hopeful campaign.

We are enforcing a victory already won, oh Hallelujah!

Paul ends that chapter by thanking God, “who gives us the victory through our Lord Jesus Christ.”

The command of Chapter 16 is the marching order of Chapter 15’s triumph.

So what changes this week? First, our posture.

Anxious striving gives way to humble dependence.

We stop searching inside ourselves for courage we never had and look to the One who has it.

Then come the practical habits.

Before you reach for your phone each morning, ask God aloud to strengthen you by his Spirit, and mean it.

Feed on the promises of his Word through the day, because no soldier fights well on an empty stomach.

And stay in the line.

Gather with fellow believers, and tell one trusted brother or sister where you are weakest.

Isolated soldiers fall first.

Then walk into your workplace, your home, your school and your neighbourhood without the panic of a man guarding himself.

Walk in as one who is being upheld, continually.

Watch. Stand fast. Be brave.

And let yourself be made strong. Amen!
