God’s knowledge is not gathered slowly, improved by observation, or limited by distance. He knows all things perfectly. Scripture makes this truth both searching and consoling: the Lord sees the hidden heart, yet He also knows the needs, griefs, and weaknesses of His people before they speak.
READ THE KEY PASSAGES
Begin with what
Scripture says.
Psalm 139:1–2O LORD, thou hast searched me, and known me. Thou knowest my downsitting and mine uprising, thou understandest my thought afar off.
Isaiah 46:10Declaring the end from the beginning, and from ancient times the things that are not yet done.
Hebrews 4:13Neither is there any creature that is not manifest in his sight.
01
God knows without limitation
1 John 3:20God is greater than our heart, and knoweth all things.
God’s understanding is infinite. He does not discover facts, forget details, guess about tomorrow, or need someone to inform Him. The past, present, future, visible world, and hidden heart are all open before Him.
This distinguishes God from every creature. Even the wisest human being knows only in part and may use knowledge badly. God’s knowledge is complete and joined to perfect wisdom, holiness, and righteousness.
God knows every heart, word, motive, and act without error. His knowledge is not discovered over time like ours.
02
God’s knowledge searches the heart
Psalm 147:5Great is our Lord, and of great power: his understanding is infinite.
Psalm 139 is personal. God knows a person’s sitting and rising, words before they are spoken, and thoughts from afar. No hidden motive, private sin, or carefully managed appearance can keep Him from seeing what is true.
That should destroy hypocrisy. A person may impress a church, family, or audience while hiding his heart from all of them. He cannot hide from God. Yet the same truth invites honesty: there is no need to pretend before the One who already knows.
That knowledge exposes secret sin, but it also means that no grief, fear, or faithful act is hidden from Him.
03
God knows the future without uncertainty
1 Samuel 16:7Man looketh on the outward appearance, but the LORD looketh on the heart.
Isaiah places God’s declaration of the end from the beginning beside His sovereign purpose. He is not waiting to see whether history will escape His plan. Prophecy, fulfilled promise, judgment, and future hope rest on the God who knows and accomplishes what He declares.
This does not turn human beings into machines or make their choices meaningless. Scripture holds people accountable for what they do. But their decisions do not surprise the Lord, and His purposes are never endangered by the limits of human knowledge.
God’s foreknowledge should produce humility. Human beings cannot correct His judgment by incomplete information or persuasive appearances.
04
God’s knowledge comforts prayer and repentance
Matthew 6:8Your Father knoweth what things ye have need of, before ye ask him.
Jesus says the Father knows what His children need before they ask, then teaches them to pray. Prayer is not supplying God with missing information; it is trusting dependence on the Father who knows. In suffering, a believer may not know why a trial has come, but he is not overlooked.
God’s knowledge also gives confession its honesty. He already sees the sin we are tempted to soften. The wise response is not concealment but repentance, trusting the mercy He has provided in Christ.
The God who knows completely is also wise and good. Believers may bring honest questions to Him without assuming His knowledge is limited by theirs.

God is omniscient: He knows all things perfectly and without limit. That truth exposes pretense, secures the promises of Scripture, and comforts believers who pray and suffer before a Father who knows them completely.
