Have you ever been watching a movie, and one of the characters hears a noise in the dark basement? Just minutes before, that same character was being warned about the danger that lurks in the darkness. You, the viewer, know that the threat is now close at hand in the basement. But the character—who should know better—grabs the faulty flashlight from the kitchen drawer and heads down the dark, cobwebby stairs. You know this action is irrational and reckless, but no matter how much you yell at the screen, they just keep going.

Fear makes you stupid.

Your brain has distinct parts that control various functions. The amygdala is the part of the brain that processes fear. It assesses threats and triggers reactions in the body that prepare us—using our sympathetic nervous system—for whatever is coming next. Our heart rate rises, pupils dilate, and adrenaline is released. The amygdala is also the seat of emotions, so the decisions it makes are primarily based on how things feel.

However, while the amygdala is running full throttle when we are afraid, the prefrontal cortex—which is responsible for helping us make rational decisions—is being impaired. Making logical decisions, such as not going into the dark basement where danger lurks, becomes difficult. So, when I say fear makes you stupid, the science backs me up.

Fear made the disciples see a ghost instead of salvation, and fear makes us see the worst possible outcomes in our future. When we face a difficult conversation, a negative life change, or an uncomfortable situation, fear can create a destructive cycle. We are afraid, so we imagine the worst—which leads to more fear—and so on.

The thing I love in this week’s passage is the change that happens when the disciples realize Jesus is in the situation.
“Take heart; it is I. Do not be afraid,” Jesus shouts over the waves. And the disciples go from being afraid of ghosts to being pretty bold. When Peter jumps out of the boat into a storm, it is one of the boldest steps of faith in Scripture. However, he then starts to sink when fear takes over again.

Jeffrey Melvin and I were discussing the concept of fear the other day, and he shared a little phrase that we would do well to remember. He said, “You can think yourself out of fear, but you can’t feel yourself out of fear.” So let us take a moment to think about the reasons we have to not be afraid.

I love Psalm 27’s pattern of statement followed by a rhetorical question:

The Lord is my light and my salvation — (STATEMENT)
Whom shall I fear? — (RHETORICAL QUESTION)
The Lord is the stronghold of my life — (STATEMENT)
Of whom shall I be afraid? — (RHETORICAL QUESTION)

We should remember this pattern as we face fearful situations. If we make the Lord our light, then He can reveal our fears for what they truly are—not what we imagine them to be. Light is a powerful antidote to fear. There’s a reason most horror movies take place in the dark.

If we make the Lord our salvation, then we are no longer responsible for saving ourselves. There is so little in life that we truly control. If our salvation depended on us, we would have much to fear—weak and limited as we are. But if the Lord is our salvation, then we are looking to the Almighty Creator of the universe, a much more trustworthy option when it comes to navigating our situation.

Finally, if we make the Lord our stronghold, then we have a place to rest. A stronghold is safe from enemies—whether they are ghosts in the storm, relationship strife, or looming layoffs. God wants you to know that you are safe with Him. There is nothing we have to fear. Even death holds no fear for those who believe in Jesus.

So take a minute today to identify the areas of fear in your life. As you think about them, listen to Jesus calling to you:
“Take heart; it is I. Do not be afraid.”
Make Jesus your light, salvation, and stronghold in that situation. And if things get worse, call out to Him. Don’t let fear take the place that Jesus wants to occupy in your life.
