What Is the Omniscience of God?

Omniscience declares that God knows everything — not merely everything that exists, but everything that could exist; not merely everything that has happened, but everything that will happen; not merely every action, but every thought, intention, and motive. ThePsalmist sang, 'Great is our Lord, and of great power: his understanding is infinite.' God's knowledge is not acquired through observation, deduction, or experience. He does not learn, discover, or improve His understanding. His knowledge is inherent, eternal, and complete. He 'calleth those things which be not as though they were,' for He knows the end from the beginning. ThePsalmist expressed this with wonder: 'O LORD, thou hast searched me, and known me. Thou knowest my downsitting and mine uprising, thou understandest my thought afar off. Thou compassest my path and my lying down, and art acquainted with all my ways. For there is not a word in my tongue, but, lo, O LORD, thou knowest it altogether.' Nothing is hidden from God. 'All things are naked and opened unto the eyes of him with whom we have to do.' This is both comforting and terrifying. Comforting, because the God who knows our darkest failures also loves us enough to send His Son. Terrifying, because we cannot hide from His gaze. Adam and Eve tried to hide in the garden, but God called, 'Where art thou?' — not because He didn't know, but because they needed to confess. God's omniscience has profound implications for prayer. He knows what we need before we ask, yet He commands us to ask. Prayer is not information transfer but relationship — aligning our hearts with His will. Jesus taught, 'Your Father knoweth what things ye have need of, before ye ask him.' This frees prayer from manipulation and grounds it in trust. God's omniscience also undergirds His sovereignty. He knows the future because He plans the future. 'Known unto God are all his works from the beginning of the world.' His foreknowledge is not passive prediction but active determination. Every event unfolds according to His eternal purpose. This does not negate human responsibility, for God knows the future precisely because He knows how free creatures will act in the circumstances He ordains. The mystery of divine omniscience and human freedom is beyond full human comprehension, but both are affirmed in Scripture. For the believer, God's omniscience is the foundation of security. 'I am persuaded, that neither death, nor life, nor angels, nor principalities, nor powers, nor things present, nor things to come, nor height, nor depth, nor any other creature, shall be able to separate us from the love of God, which is in Christ Jesus our Lord.' Nothing surprises God, nothing escapes Him, and nothing can separate His children from His love.
