Bible Study · Psalm 139 And The God Who Knows

God Is Omniscient: Fully Known, Fully Loved

God knows everything, including the parts of you nobody else has seen. Scripture never presents that as a camera on the wall. It presents it as the reason you can stop hiding.

The Short Answer

Everything, And Still For You

Straight Answer

God is omniscient means God knows everything there is to know: every thought, every motive, every detail of your life, what has happened and what lies ahead. In Scripture that knowledge is almost always given as comfort, not threat.

The God who knows the worst about you is the same God who sent His Son for you. Being fully known and fully loved by the same Person is the whole point.

The Bible never uses the word. It gives us a long line of people finding out they have been seen, and discovering that the One who sees them is not looking for a reason to leave. The hard question about foreknowledge and free will gets an honest hearing below.

Psalm 139

Searched And Known

Psalm 139 is the fullest meditation on God's knowledge in the Bible, and it is written as a prayer, not a lecture.

“O LORD, you have searched me and known me! You know when I sit down and when I rise up; you discern my thoughts from afar. … Such knowledge is too wonderful for me; it is high; I cannot attain it.”

Psalm 139:1 to 2, 6 · ESV

Notice David's reaction. He does not flinch. He calls it wonderful. In verses 7 to 12 he asks where he could go from God's Spirit, and the answer is nowhere: not the heights, not the depths, not the dark. And by the end, the knowing has turned into an invitation. Search me, O God, and know my heart. Lead me in the way everlasting.

Hebrews 4:13

No creature is hidden from His sight. The very next verses introduce a high priest who sympathizes with our weaknesses. The writer puts exposure and mercy side by side on purpose.

1 John 3:20

Whenever our heart condemns us, God is greater than our heart, and He knows everything. John uses omniscience to quiet an accusing conscience, not to feed it.

Matthew 6:8

Your Father knows what you need before you ask Him. Jesus says it to free people from piling up empty phrases, as if God had to be informed or worn down.

Matthew 10:30

Even the hairs of your head are all numbered. The next words are fear not. The detail is there to tell you your value, more than many sparrows.

Takeaway

Every major text on God's knowledge lands in the same place. Because He already knows, you do not have to perform, explain yourself, or hide.

Saying It Plainly

Known, Not Watched

A lot of people grew up with a different version. God as the eye in the corner of the room, keeping the record, waiting for you to slip. It usually got used on children to keep them in line, and it follows many of them into adulthood.

That picture is wrong, and it is wrong because of Jesus, not in spite of the Bible. The texts that say God sees everything say it to steady people who are hurting or ashamed.

The Surveillance Picture

God sees everything so He can catch you. His knowledge is a file being built for the day it gets read out. The right response is to keep your head down.

The Picture Scripture Gives

God sees everything, so there is nothing left to hide or manage. The One who knows the file came to carry it. The right response is to come near, which is exactly what Hebrews 4:16 says.

This cuts the other way too. Being known is not the same as being approved of in everything. Hebrews 4:13 does mention giving account, and 1 John is not telling anyone that what they do does not matter. Being seen clearly is how healing starts.

If You Have Been Hiding

If there is something in your life you have never said out loud, hear this. God is not going to find out. He already knows, and He has not left. That is what John means when he says God is greater than your heart.

You do not need to clean it up before you bring it. If it would help to say it to a person, send us a prayer request and someone will pray it through with you, quietly and without judgment.

Read Through Jesus

The God Who Knew Peter

If you want to know what God does with what He knows, watch Jesus.

John 1:48
Nathanael Under The Fig Tree

Jesus tells him He saw him under the fig tree before Philip called him. Nathanael goes from skeptic to disciple in one conversation.

John 4:18 To 29
The Woman At The Well

Jesus names her five husbands and her present situation. She runs into town saying, “Come, see a man who told me all that I ever did.” Being known sent her toward people, not away from them.

Luke 22:32 To 34
The Denial, Foretold

Jesus tells Peter he will deny Him three times, and in the same breath says, “I have prayed for you that your faith may not fail.” The prayer comes before the failure.

John 21:17
Peter Restored

Asked a third time whether he loves Jesus, Peter answers, “Lord, you know everything; you know that I love you.” Jesus replies, “Feed my sheep.”

Peter appeals to the very knowledge that saw his denial coming, and makes it the ground of his restoration. It also answers the worry that knowing a thing ahead of time means causing it. Jesus knew Peter would deny Him. He did not make Peter do it. He prayed over it and restored him afterward. We made the same point about Judas in predestination in the Bible: foreknown, not forced.

When Peter says “Lord, you know everything” in John 21:17, what is he leaning on?

Proof that Jesus is watching for his next failure
Jesus' knowledge of his love, even after the denial
A reason to keep his distance from Jesus

The same knowledge that foresaw the denial can also see Peter's love. Peter does not hide from Jesus' omniscience. He rests his whole case on it, and Jesus hands him a job.

The Hard Texts

When God Regrets And Tests

Honest readers run into verses that seem to cut against all of this.

“And the LORD regretted that he had made man on the earth, and it grieved him to his heart.”

Genesis 6:6 · ESV

Then in Genesis 22, after God tested Abraham, the angel of the LORD says, “now I know that you fear God.” Read flat, that sounds like God finding something out. If He already knew, why test? And if He knew how humanity would turn out, how could He regret making it?

HebrewNachamנָחַםRegret, Relent, Comfort
Range

A verb with a wide reach. Strong's gives to be sorry, to pity, to console, and in other forms to comfort oneself or to repent. It is a word of feeling.

Genesis 6:6

The LORD regretted making humanity, and the verse immediately adds that it grieved Him to His heart. The weight falls on pain.

1 Samuel 15

Verse 11 has God say, “I regret that I have made Saul king.” Verse 29 says He “is not a man, that he should have regret.” Same verb, same chapter, on purpose.

Jonah 3:10

When Nineveh turned from its evil way, “God relented of the disaster that he had said he would do to them.” A God who responds.

Here is how we read these. Genesis is telling the truth about God's heart in the language of human experience, which is how Hebrew narrative speaks of God all the way through. The regret in Genesis 6 is grief. God is not a database with perfect records and no feelings. He is moved by what we do.

Genesis 22 works the same way. The test is for Abraham, and for every reader after him. “Now I know” is the story bringing into the open, in action, what had been true in the heart. We walk through the details of that morning in how old Isaac was on Mount Moriah.

In fairness, open theists read these verses more literally, as a God who genuinely learns and changes course. We think 1 Samuel 15, holding regret and no regret in one chapter, shows the writers were not confused. They knew God is not fickle the way people are, and they still insisted He feels.

Takeaway

The regret texts do not show a God caught off guard. They show a God who is not indifferent. Omniscience without grief would not look like Jesus weeping outside Lazarus's tomb.

Foreknowledge And Free Will

Three Ways Christians Hold It

If God knows today what you will choose tomorrow, is tomorrow's choice really free? Serious Christians answer differently. Here are three answers at full strength.

Classical

God knows the whole future, completely and without error. Many in this tradition follow Boethius, who pictured God outside time, so that, as Linda Zagzebski summarizes him in the Stanford Encyclopedia of Philosophy, “all temporal events are before the mind of God at once.” God does not so much foresee your choice as see it. Its strength is that nothing takes God by surprise.

Molinist

God also knows what any free person would do in any possible situation, and chooses which world to create knowing all of it. Its texts include 1 Samuel 23, where God tells David the men of Keilah would hand him over if he stayed, so he leaves, and Matthew 11:21, where Jesus says Tyre and Sidon would have repented. Its strength is full providence with real freedom.

Open View

God made a world with free creatures in it, so part of the future is genuinely open, and He knows it as open: every possibility and every likelihood, but not free choices not yet made. Open theists argue that a God “who takes risks, and can be surprised and even disappointed at how things turn out” fits Scripture better, in the same entry's summary. Its strength is that it takes prayer and the relational texts at face value.

Where We Stand, Plainly

Our position at Sound of Heaven is that God knows everything, including what lies ahead. The prophets, the cross itself, “delivered up according to the definite plan and foreknowledge of God” in Acts 2:23, and Jesus telling Peter what the night would hold all point the same direction. God is not guessing, and He is not waiting on the sidelines to see how things turn out.

We also hold that knowing is not causing. God's foreknowledge does not make anyone sin. That is why we read Exodus the way we do in why God hardened Pharaoh's heart, and why we say in did God create evil that evil belongs to the ones who choose it. Our choices are real, and so is our responsibility.

Between the classical and Molinist accounts we do not pick a winner. We think the open view is right about the relational texts even though we do not share its conclusion about the future. How full foreknowledge and real freedom fit together is an open file. We hold Scripture's claims firmly and the mechanism loosely.

And we refuse the error on both sides: a God who knows everything because He scripted everything, and a God so limited He cannot be trusted with tomorrow. Neither one looks like Jesus.

Where This Lands

Seen All The Way Through

Omniscience is not finally a puzzle to solve. The God who knows everything came near in Jesus, told people the truth about themselves, and stayed.

So the fact that God knows you is the safest fact in your life. He knows what you need before you ask, which is not a reason to stop praying but a reason to pray without performing, as we explain in why pray. He has numbered the hairs on your head, which is His way of saying you matter down to the details. And when your own heart condemns you, He is greater than your heart.

If you are on Long Island and want to be somewhere people are known by name, come find a seat with us.

The Whole Thing In One Line

God knows everything, including tomorrow and the worst about you, Scripture gives that knowledge as comfort rather than surveillance, knowing is not causing, the regret texts show a God who feels, and in Jesus the One who knows you best is the One who loves you most.

Questions People Ask

Questions About God's Knowledge

What does it mean that God is omniscient?

It means God knows everything there is to know. Psalm 139 says He discerns our thoughts from afar and knows a word before it is on our tongue. Hebrews 4:13 says no creature is hidden from His sight, and 1 John 3:20 says simply that He knows everything. That includes the past, the present and what lies ahead. In Scripture this knowledge is offered as comfort, from the God who loves you and came near in Jesus.

Does God know the future if we have free will?

We believe He does, and we believe our choices are still real. Knowing something will happen is different from making it happen. Jesus knew Peter would deny Him and did not force the denial. Christians explain how the two fit in different ways. The classical view pictures God seeing all of time at once. Molinism says God also knows what free people would do in any situation. Open theism says part of the future is still open. We hold that God knows the future and that the exact mechanism is an open question.

Why does the Bible say God regretted making man?

Genesis 6:6 uses the Hebrew verb nacham, which can mean to be sorry, to pity or to relent, and the verse adds that it grieved Him to His heart. The point is grief, not surprise. Hebrew narrative speaks of God in the language of human experience, and 1 Samuel 15 shows the writers knew it, since one chapter says God regretted making Saul king and also that He is not a man, that He should have regret. God is not indifferent to what we do. He feels it.

Why did God test Abraham if He already knew?

Genesis 22:1 says God tested Abraham, and verse 12 says, now I know that you fear God. The classical reading is that the test brought into the open, in action, what God already knew, for Abraham's sake and for every reader after him. Open theists take the verse more literally, as God learning through the event. Either way the story ends with God providing the ram in place of the son.

If God knows what I need, why pray?

Jesus answers this in Matthew 6:8. He says your Father knows what you need before you ask Him, and in the very next verse He teaches the Lord's Prayer. Prayer is not informing God or wearing Him down with many words. It is relationship. Because He already knows, you can come honestly, without a speech prepared, and trust that you are heard. Scripture also shows God genuinely responding to prayer.
