The Monkey Brain


Listen Later

Not every thought in your head belongs to you.

That is not a metaphor. That is not an exaggeration for effect. It is one of the most practically important truths Scripture gives us about the inner life of a human being, and most of us have never slowed down long enough to actually reckon with it.

We assume our thoughts are our own because they feel familiar. They arrive in our own voice, in our own mental language, shaped by our own experiences and memories. So we claim them... We act on them. We sometimes feel guilty about them, as though the mere presence of a dark or destructive thought is evidence of something broken in our character. But the Bible draws a line that our culture rarely does, a clear, deliberate line between two entirely different sources of thought operating inside every human being simultaneously.

Two Sources, One Mind

Scripture teaches that man’s inner life flows from two distinct origins. The first is the God-given spirit, the part of us that was made for communion with God, that recognizes truth, that longs for what is holy and eternal. The second is the flesh, the sin nature inherited from Adam’s fall, which did not disappear at conversion but continues to operate alongside the spirit in a constant, grinding opposition.

Paul describes this tension without softening it in Romans 8. The mind set on the flesh, he writes, is hostile to God. Not indifferent. Not occasionally distracted... Hostile. It does not submit to God’s law and frankly cannot. It is not designed to. The flesh thinks thoughts that serve the flesh, and those thoughts feel completely natural because they arrive through the same mental infrastructure we use for everything else.

This is what makes the flesh so effective as an adversary. It does not announce itself. It does not arrive with a warning label. It slips thoughts into our stream of consciousness so seamlessly that we assume we authored them. We have even given this phenomenon a casual, almost affectionate nickname... the monkey brain. As if restless, self-serving, destructive thought patterns are simply a quirk of human neurology rather than what Paul would call the mind of the flesh making its presence known.

Higher Than Our Highest

Isaiah 55 adds a dimension to this that should give us pause. God declares through the prophet that His thoughts are not our thoughts, and His ways are not our ways. The distance between them is not slight. It’s the vast distance between snail and eagle… sheep and lion… earth and the heavens... It’s immeasurable.

Which means that when the flesh is generating thoughts and calling them intuition, when it is producing feelings and calling them instinct, when it is creating urges and calling them desire... none of that is operating anywhere near the plane of what God actually intends for us. The flesh is not just unhelpful. It is pulling in the precise opposite direction of God’s purpose, and doing so quietly, from the inside.

Three Snares Worth Naming

The flesh tends to work through three specific channels, and recognizing them is the beginning of not being controlled by them.

The first is a thought that steers you away from your true, God-given intentions. A sudden doubt. A critical judgment that hardens into bitterness. A justification for something you already know is wrong, arriving just when you need a reason to proceed.

The second is a feeling that, left unchecked, leads you away from God rather than toward Him. Anger that becomes resentment. Sadness that slides into despair. Desire that detaches from wisdom. Feelings are real, but they are not always truthful, and the flesh is skilled at using them as a steering mechanism.

The third is an urge, a craving or impulse that pulls you from the Word and the life it calls you to. Something that feels urgent and necessary in the moment but leaves you further from God once it is satisfied.

None of these snares are unique to you. Every human being who has ever lived has navigated this same interior battlefield.

The Only Way Through

God is not surprised by any of this. He knew what Adam’s fall would introduce into the nature of every human being born afterward. And He did not leave us to manage it alone through willpower or moral effort.

The path through is the renewed mind. Paul writes in Romans 12 that transformation comes not through trying harder but through the renewing of the mind by the Holy Spirit. The same Spirit that raised Jesus from the dead, alive and active inside every believer, has the power to progressively rewire how we think, what we desire, and how we respond to what the flesh puts in front of us.

There is an old story about two wolves living inside every person, constantly at war. One is good. One is destructive. The grandson asks which one wins. The grandfather answers simply: the one you feed.

Starve the flesh... Feed the spirit. Not as a motivational slogan, but as a daily, deliberate, Spirit-empowered practice.

The thoughts will keep coming. The question is whether you have learned to ask whose they are before you decide what to do with them.

On Wednesday, we go deeper into this topic by diving into the scriptures with a devotional. We’ll let biblical teachings help us deal with this monkey brain and ever determined wolf whose goal is to devour us. Don’t be scared of the passenger that hides in the wake… deal with him. Take solace in now being aware of the enemy that was shielding itself in darkness, and attacking when no one was looking… the tables have turned.
