God Is All-Knowing (Omniscient) – Psalm 147:5

God Is All-Knowing (Omniscient) – Psalm 147:5

You’ve probably asked at one time or another, “Does God really know everything about me?” It’s a tender question, and it gets to the heart of who God is. The Bible calls God omniscient — all-knowing. That truth brings comfort when you’re afraid, conviction when you’re hiding something, and hope when you’re confused. In Psalm 147, the psalmist declares a truth about God that anchors the believer’s soul: His understanding has no limit. Let’s sit with that verse and explore what it means for you, how Scripture witnesses to it, and how this attribute of God should shape your life and your faith.

Psalm 147:5 — the verse that begins the conversation

Psalm 147:5 says, “Great is our Lord and mighty in power; his understanding has no limit.” When you read that, you sense the awesomeness and the tenderness of God wrapped together. He is majestic and powerful, and yet the reason He is worthy of your trust is because His understanding is limitless. You aren’t dealing with a distant power that sometimes knows and sometimes doesn’t. You are held by One whose comprehension reaches every moment, every thought, and every need.

What “omniscient” really means

When theologians use the word omniscient, they mean God knows everything that can be known — past, present, and future. That includes the choices you will make tomorrow, the prayers you won’t speak aloud, and the deepest motives of your heart. This understanding isn’t cold or merely theoretical; it is personal and compassionate. God’s knowledge of you is not like a scientist observing a specimen but like a father who knows his child’s name, the sound of their laughter, and the places they hurt.

God knows your whole story

You might be carrying a life story full of twists you wish were different. The Bible reminds you that God’s knowledge isn’t limited to facts and events; He knows the whole narrative. In Psalm 139:1 David cries out, “You have searched me, Lord, and you know me.” That searching is intimate, not invasive. It is the kind of knowledge that leads to care and restoration. When you think God doesn’t understand your particular sorrow or confusion, remember that He has searched you and knows you intimately.

God knows your inner thoughts and motives

It’s easy to be honest with others and still hide things from yourself. But nothing is hidden from God. Psalm 139:2 tells you, “You know when I sit and when I rise; you perceive my thoughts from afar.” Your fleeting thoughts, secret anxieties, private longings — God perceives them all. This reality can bring you to repentance when you need to change and to courage when you need to be honest before God.

Scripture’s clear testimony to God’s knowledge

Scripture does not leave the matter to assumption. The Bible repeatedly and powerfully testifies that God’s knowledge is complete. These passages aren’t abstract dogma; they are invitations to trust a God who sees you and cares.

Nothing is hidden from God — Hebrews 4:13

Hebrews 4:13 states it plainly: “Nothing in all creation is hidden from God’s sight. Everything is uncovered and laid bare before the eyes of him to whom we must give account.” That means your failures, your secret pains, and your deepest joys are all known to Him. When you stand before God, it will not be a surprise to Him. The certainty of His knowledge invites you to live honestly now, to confess what needs confessing, and to rest in His gracious assessment rather than your own fearful imagination.

God knows your days before you live them — Psalm 139:16

Psalm 139:16 says, “All the days ordained for me were written in your book before one of them came to be.” You might worry about the unknown future, but God has not been surprised by a single detail of your life. That doesn’t remove your responsibility to make choices, but it gives you the comfort that your life is not random and that God’s purposes are at work even through difficulties.

God knows your needs before you ask — Matthew 6:8

When Jesus taught about prayer, He reminded you of Father’s intimate knowledge: “Matthew 6:8 ‘Your Father knows what you need before you ask him.’” You don’t have to prove your needs to God with eloquent words. He already knows them. This truth invites you to come to God in simple, honest prayer with confidence that He cares and understands.

God knows the final heartbeat of human life — Isaiah 40:28

Isaiah 40:28 encourages you, “Do you not know? Have you not heard? The Lord is the everlasting God, the Creator of the ends of the earth. He will not grow tired or weary, and his understanding no one can fathom.” That means God’s knowledge is not only infinite in scope but inexhaustible. He is never distracted, never worn out, and never unaware. Your struggles do not exhaust Him.

God knows every place you go — Jeremiah 23:24

The prophet Jeremiah recorded God’s rhetorical question: “‘Can anyone hide in secret places so that I cannot see him?’ declares the Lord. ‘Do I not fill heaven and earth?’” (Jeremiah 23:24). When you feel alone or invisible, you are not invisible to God. You are never outside His presence.

Why God’s omniscience matters to you practically

Understanding that God is all-knowing is not merely doctrinal trivia; it changes how you live, think, and pray. This truth gives you comfort, conviction, guidance, and hope.

Comfort when life is confusing

When you face suffering and don’t understand why God allowed it, His omniscience is your consolation. He sees the big picture you cannot yet see. Romans 8:28 offers the promise that “in all things God works for the good of those who love him, who have been called according to his purpose.” You may not see today how a painful event will be used, but you can trust the One who knows all.

Courage to be honest and repentant

Because God knows your thoughts and motives, you don’t have to perform for Him. Confession becomes a freeing act rather than a fearful ordeal. 1 John 1:9 tells you, “If we confess our sins, he is faithful and just and will forgive us our sins and purify us from all unrighteousness.” The knowledge God has of you is not meant to shame but to invite you into cleansing and restoration.

Guidance in decision-making

You face choices every day. Knowing God is omniscient means you can seek guidance from someone who knows all options and consequences. Pray honestly, seek Scripture, and trust God to lead. Sometimes His guidance comes through peace in your heart, wise counsel, or doors opening or closing. Trust the Lord who knows the end from the beginning.

Accountability and moral urgency

God’s knowledge of your heart brings serious hope and serious warning. There is accountability in God’s omniscience — not to crush you with fear, but to correct and refine you. Hebrews 4:13 reminds you that everything will be laid bare before the One to whom you must give account. That should stir you to live a life of repentance and integrity today.

Common questions and concerns about omniscience

When you think about a God who knows everything, a few questions naturally arise. How does God’s knowledge relate to your freedom? Does God’s foreknowledge mean your choices are meaningless? These are important and pastoral issues.

Does God knowing the future take away your free will?

You might worry that if God already knows your choices, then your free will is an illusion. But Scripture presents both truths: God knows and you are responsible for your choices. God’s knowledge does not coerce your will. He knows what you will freely choose because He is outside of time and perfectly knows all things. You still make real choices, and those choices have real consequences. The Bible holds both God’s sovereignty and human responsibility in tension.

If God knows everything, why does He ask questions?

You’ll notice in Scripture that God sometimes asks questions — not because He lacks information, but to draw you out, to teach, and to invite response. For example, Jesus asked Peter, “John 21:17 ‘Do you love me?’” He knew Peter’s heart, but He asked to restore and commission him. God’s questions are pastoral; they’re meant to awaken your conscience and lead you to deeper faith.

Why doesn’t God prevent every evil if He knows it will happen?

This is the age-old problem of evil. Omniscience does not demand that God override human freedom or remove the moral reality of choices. At the same time, His knowledge is coupled with His power and goodness. He allows human freedom but works inside history to bring redemption from evil. The cross is the ultimate demonstration — God knew the evil, yet He used it for our redemption through Christ.

How omniscience shapes your prayer life

Your prayers change when you truly believe God knows everything. Instead of praying to inform God, you pray to commune with Him, to align your heart with His purposes, and to receive His grace.

Pray with honesty and simplicity

Since God knows the depth of your need, you can come with raw, simple words. Jesus said that your Father knows what you need before you ask (Matthew 6:8). You don’t have to craft perfect theological speeches. Speak from the heart. Tell God your fears, your hopes, and your gratitude.

Use Scripture in prayer

When you pray, let Scripture shape your words, because Scripture reflects God’s own knowledge and truth. Pray David’s words in Psalm 139:23–24: “Search me, God, and know my heart; test me and know my anxious thoughts. See if there is any offensive way in me, and lead me in the way everlasting.” Those prayers invite God’s searching into your life in a trusting way.

Rest in God’s timing

You may pray for an answer and not see it immediately. God’s timing is perfect because His knowledge is perfect. Trust Him even when the “how” and “when” of His answers remain mysterious.

Living honestly before a God who knows

If God knows everything about you, what does that mean for your daily living? It shapes your honesty, your priorities, and your sense of purpose.

Practice transparency with God and others

Because nothing is hidden from God, secrecy has less power over you. Be honest in your relationships and in your walk with God. James tells you to confess your sins to one another so you may be healed (James 5:16). Confession breaks isolating shame and sets you on a path to restoration.

Pursue holiness from gratitude, not guilt

God’s knowledge is not merely to convict; it’s to motivate worship and holiness. When you remember that God knows you intimately and loves you, your pursuit of holiness will flow out of gratitude rather than mere fear. God’s omniscience reveals His care and invites your joyful obedience.

Share the good news confidently

When you understand that God knows every heart, you’ll be bold to share the gospel with people you might think are unreachable. God is already at work in ways you don’t see. Trust that His knowledge meets people where they are, and let that prompt you to speak lovingly and urgently about Christ.

The comfort and the challenge of being known

There is immense comfort in being fully known by God: you are not anonymous in the universe, and your life matters to the Creator of heaven and earth. But that knowledge also challenges you to honesty, repentance, and faithful living.

Comfort: You are never overlooked

When you feel invisible in a crowded world, remember Psalm 147:5 — God’s understanding has no limit. He notices the small things that matter to you. He remembers the cries of those who have no voice, the tears you wipe away when no one is looking, and the quiet prayers you whisper at night.

Challenge: live with integrity

Knowing that God knows every motive is a call to integrity. Live consistently, privately and publicly. Let your inner life match your outer life. When you do, you reflect the character of the One who knows you best.

If you don’t yet know this God personally

If you’ve read this and feel a stirring — a sense that you want this God who knows you to be your Savior and Lord — take a step today. Scripture speaks plainly about the way to new life.

The gospel: knowledge meets mercy

You are a sinner in need of grace; God knows that reality about you intimately (Romans 3:23). Yet He loves you and sent His Son, Jesus, to die and rise for you so that you might be forgiven and restored. Romans 6:23 promises the gift of God is eternal life through Jesus Christ. If you confess with your mouth that Jesus is Lord and believe in your heart that God raised Him from the dead, you will be saved (Romans 10:9). God’s knowing you becomes the most tender and life-changing reality when you receive Christ.

A simple step you can take now

If you want to turn to Christ, speak to God in simple, honest words. Tell Him you know you’ve fallen short, ask for forgiveness, and invite Jesus to be your Lord. God already knows your heart — He’s waiting to meet you with mercy.

Final reflections — live under the gaze of grace

You’ve seen that God’s omniscience is not a cold theological fact but a warm, living reality that invites you into deeper trust and obedience. He understands you in ways no human can. He knows your past and holds your future. He knows your pains and hears your prayers. Let this truth draw you closer to Him in worship, honesty, and hope.

You don’t face life alone. The all-knowing God watches over you with endless understanding and unfailing love. Let that truth steady your heart today. Let it shape how you pray, how you confess, and how you reach out to others. May you live with the confidence that the Maker of the universe knows your name, remembers your tears, and holds you in tender care.
