For there is not a word on my tongue, but behold, O LORD, You know it altogether.
Job 23:9-11 The original goal of Google Books, which began in 2004, was to digitize (scan the pages of) “all” the world’s books—and by extension, all the world’s knowledge. Many copyright issues have delayed the project over the last 10 years, but as of April 2013, Google Books’ database contained more than 30 million scanned books.
Only part of the world’s knowledge is contained in books, so no database of scanned books could contain all knowledge. But there is a “database” that does: the mind of God. “Omniscient” is the word used to describe God’s infinite, all-encompassing knowledge. He knows not only what has happened but what has not yet happened. David understood that God knew what he would say before he spoke the words, and where he would walk before he took a step (Psalm 139:4, 16). Jesus said God knows the number of hairs on our head and knows when a sparrow falls from the sky (Matthew 10:29-30).
God’s omniscience warns us to avoid sin and comforts us when we wonder about the future. God knows what we know and everything we don’t.
Because God knows all things perfectly, He knows no thing better than any other thing, but all things equally well. He never discovers anything, He is never surprised, never amazed.
