What Does It Mean That God Is Omniscient?
Could God ever learn something new?
Writing content for this blog has been a learning experience. Each time I write a piece, I check what Scripture and historic Christianity teach about the subject.
That said, I often come across videos online featuring people who seem reputable and charismatic. Sometimes they even have a good number of subscribers.
Today, I found someone claiming with full conviction, “God is not omniscient; in fact, He has limited powers.”
The Nicene Creed confesses God as Almighty. That mainly refers to His unlimited power, while omniscience refers to His complete knowledge. This person somehow managed to reject both.
For this reason, and many others, we should study theology so that we do not fall into false teachings.
“Aren’t two sparrows sold for a penny? Yet not one of them falls to the ground without your Father’s consent. But even the hairs of your head have all been counted.”
—Matthew 10:29–30 (CSB)
The first time I read this verse, I said to myself, “Wow.” I mean, God knows how many hairs I have on my head; I can barely remember what I ate three days ago for dinner.
In this guide, we’ll explore what it means to say that God is Omniscient, what He knows about us, why nothing can be hidden from Him, and why being completely known by God can be both uncomfortable and comforting.
Key Takeaways
- God does not need to learn anything. He already knows the past, present, and future, including our actions, thoughts, motives, and choices.
- God’s omniscience can feel uncomfortable because we cannot hide from Him. But it is also comforting because He knows our struggles, intentions, and the parts of our story that others may misunderstand.
- God knowing our future choices does not mean He forces us to make them. His foreknowledge does not remove our freedom or responsibility.
- Prayer is not about giving God information He somehow missed. We pray to have communion with Him, depend on Him, and trust His knowledge when we cannot see what lies ahead.
Omniscience Means God Never Needs to Learn Anything
God is not a man upstairs spending hours in His private library reading books and trying to acquire more knowledge. Come to think of it, that sounds more like me.
Anyway, God does not need to learn anything. His knowledge is already perfect and complete. God’s character is immutable, meaning He does not change.
Learning would require moving from not knowing something to knowing it—from not knowing how much 2 + 2 is, for example, to knowing that 2 + 2 = 4.
The word “omniscience” comes from:
- Omni: all
- Scientia: knowledge
In other words, God is all-knowing. He knows everything about the past, present, and future. Even if AI robots someday become like those in the Terminator movies and try to destroy humanity, God will not be caught by surprise.
God does not need to search for information, nor does His knowledge increase through learning. His knowledge also does not decrease because of old age or forgetfulness. He is eternal and is not limited by time and space as we are.
Some people may read this and think, “So, God is extremely intelligent.” Not exactly. Intelligence usually describes our ability to learn, understand, and solve problems. God is not simply more intelligent than us—He knows everything.
We should not try to measure His knowledge using IQ tests or any other human standard. There has never been anything God did not know, and there never will be.
“You Have Searched Me and Known Me”
Now, to see this doctrine in Scripture, let’s take a look at a few verses.
“Lord, you have searched me and known me. You know when I sit down and when I stand up; you understand my thoughts from far away.”
—Psalm 139:1–2 (CSB)
David recognizes that God is all-knowing. If you continue reading the passage, you see that God knows where David goes and even what he is about to say. God knows everything about him. David eventually admits that this knowledge is far beyond his understanding.
“No creature is hidden from him, but all things are naked and exposed to the eyes of him to whom we must give an account.”
—Hebrews 4:13 (CSB)
God knows our actions, motives, excuses, and secret sins. He knows our hearts completely.
Initially, I struggled to understand repentance. Not so much the idea of repenting myself, but how God could forgive someone like the Apostle Paul.
When he was still known as Saul, he persecuted Christians, dragged them into prison, and approved of Stephen’s death.
Repentance must be truthful
Then I realized something: after Paul encountered Jesus on the road to Damascus, he truly repented. His life changed, and he began following the same Jesus whose followers he had once persecuted.
That means nobody can fake repentance before God. We may say the correct words and fool everyone around us, but God knows whether we are genuinely sorry and willing to turn away from our sins.
Of course, our repentance does not earn forgiveness. God forgives us through His grace and the saving work of Jesus Christ. Genuine repentance is our response: we recognize our sin, turn back to God, and desire to change our ways.
That does not mean we will never stumble again. It means we are no longer making excuses for our sin or pretending before the God who already knows everything about us.
Being Fully Known Is Also a Comfort
It might initially sound like too much: “Gosh, God knows me better than I know myself.” But that also means He knows our hearts in every moment.
Other people may judge or misunderstand you
This seems to happen all the time nowadays, especially on the internet. Someone with a shady past converts, and people immediately start questioning whether the conversion was genuine.
