The Unseen Realm took me a very long time to read—not because I wasn’t interested, but because I constantly had to stop and process what I had just read.

This book was recommended to me by my dad. My dad and I regularly go to lunch together, and somehow those lunches have a way of turning into very deep conversations about Christianity, eschatology, and the cosmic and spiritual forces described throughout Scripture.

We are both Jesus-loving people, but my dad will absolutely disappear down a theological rabbit hole.

And apparently, I am more than willing to follow him.

There were times when I thought, Dad, you sound a little crazy.

Then I started researching.

That research eventually included reading the Bible from beginning to end and picking up The Unseen Realm.

And let me tell you something:

My father wasn’t sounding nearly as crazy anymore.

Seeing Scripture Through Ancient Eyes:

Dr. Michael Heiser’s central focus in The Unseen Realm is something many Christians rarely hear discussed in church: the supernatural worldview of the biblical writers.

Instead of reading Scripture solely through a modern lens, Heiser asks readers to consider how the ancient Israelites would have understood passages involving spiritual beings, heavenly authorities, rebellion, and God’s divine council.

And he doesn’t simply throw out theories and expect you to believe him.

He continually takes you back to Scripture.

He also digs into the Hebrew and Greek behind certain passages and explains how translation choices—or our modern assumptions about particular words—can sometimes cause us to miss what an ancient reader may have understood immediately.

That was probably the most fascinating part of this book for me.

There were verses I had read before. Verses I had heard pastors preach. Verses I had skimmed over without giving them another thought.

And suddenly I was looking at them completely differently.

The Verse That Started It All:

One of the passages at the center of Heiser’s work is Psalm 82, where God is pictured presiding over a divine council and judging among other heavenly beings.

That passage stopped Heiser in his tracks too.

According to his account, realizing what he had overlooked in that verse helped launch the research that ultimately became The Unseen Realm.

And I understood why.

For most of my life, my picture of Heaven was incredibly simple. There was God. There were angels. There were human beings who eventually went to Heaven.

That was about as far as I had ever thought about it.

Heiser’s explanation of the biblical divine council opened an entirely different way of understanding passages I had previously skimmed right over.

To be clear, he isn’t arguing that these spiritual beings are equal to God. Quite the opposite. God remains completely unique and sovereign.

But Heiser argues that Scripture describes a populated spiritual world—a heavenly family and administration under God’s authority.

Once I started seeing that framework, I began noticing it everywhere.

Genesis 6, the Nephilim, and the Supernatural World:

Heiser also spends significant time discussing Genesis 6 and the mysterious passage involving the “sons of God,” the “daughters of man,” and the Nephilim.

I knew the passage.

I just never really understood what to do with it.

Heiser interprets the sons of God as rebellious divine beings and connects their actions to a much larger biblical story about supernatural rebellion, corruption, judgment, and God’s plan to reclaim creation.

Some Christians interpret Genesis 6 differently, and I have learned firsthand that people can have very strong opinions about this passage.

I once got into a debate at work with someone who is also a pastor because we understood these passages completely differently.

But that’s part of what made The Unseen Realm so compelling to me.

It made me ask questions I had never thought to ask.

Why are these passages there?

Why do we sometimes rush past them?

Why are Christians comfortable discussing angels and demons, yet become uncomfortable when Scripture describes other spiritual beings or a divine council?

I found myself wondering why these topics are so often tiptoed around when they are sitting right there in the biblical text.

Somehow, This Strengthened My Faith:

What surprised me most about this book was what it did to my faith.

It didn’t weaken it.

It strengthened it.

The more I read, the larger the biblical story became.

Heiser presents Scripture as a story not only about humanity’s rebellion, but also supernatural rebellion—and about God’s plan to restore what was broken in both the heavenly and earthly realms.

That framework made the role of Jesus feel even more extraordinary to me.

The story becomes one of God reclaiming His creation and ultimately bringing Heaven and Earth together again so He can dwell with His people.

That idea absolutely blows my mind.

We live in a world where people will openly entertain the possibility of extraterrestrial life, alternate dimensions, and countless other mysteries of the universe.

Yet the idea that a spiritual realm populated by intelligent beings could exist sounds impossible to some people.

I find that fascinating.

This Is Not a Quick Read:

I would not call The Unseen Realm light reading.

There were sections I reread multiple times.

There were moments when I had to close the book and think.

There were passages I went back and looked up in my own Bible.

And there were plenty of moments when I wanted to call my dad and say, “Okay…keep going. Tell me more.”

Heiser supports his arguments not only with Scripture but with linguistic, historical, and scholarly sources, which makes this book feel much more like serious biblical scholarship than speculation.

You do not have to agree with every conclusion he reaches to get something valuable from reading it.

But I don’t think you can read it thoughtfully without being challenged to look at certain passages differently.

Final Thoughts:

I could write so much more about this book.

But eventually I would just end up retelling the entire thing, and I don’t want to do that.

I want you to read it.

If you’re interested in understanding Scripture more deeply, exploring the supernatural worldview of the biblical writers, or simply asking questions about passages you may have read a hundred times without really seeing them, I highly recommend The Unseen Realm.

It challenged me.

It fascinated me.

It sent me down even more rabbit holes.

And somehow, through all of that, it strengthened my faith.

Maybe some of this sounds crazy.

I’m perfectly fine with that.

Because after reading The Unseen Realm, I have a much bigger picture of God, Scripture, and the spiritual world than I did before.

And I am very glad my dad convinced me to go down this rabbit hole with him.
