What does it mean that God is omniscient (all-knowing)?
Quick answer
God is omniscient means he knows everything — past, present, future, actual, possible, every thought and motive of every heart. Nothing is hidden, nothing forgotten, nothing learned.
"His understanding is beyond measure" (Psalm 147:5). He knows the number of the stars and the hairs on your head.
God’s knowledge is not just data; it is perfect, comprehensive, and deeply personal. He knows you fully and loves you anyway.
For us: there is no need to hide. He already knows. There is also no need to fear: he sees the end from the beginning and works all things for the good of his people.
