Omniscience (Proverbs 15:5)

The Lord sees all and knows all. He is everywhere at all times.

"The eyes of the Lord are in every place, keeping watch upon the evil and the good." Proverbs 15:3, Amplified

There is nothing that can surprise the Lord. He is omniscient. According to the Dictionary of Theological Terms, omniscience, or the knowledge of God, is defined as such: "It is infinite knowledge: He knows in His own infinite being; He knows all things possible, whether they ever become actual or not; and He comprehends all these things in one simultaneous act of knowing. This knowledge is known in theology as 'the knowledge of simple intelligence' or, necessary knowledge', because God's knowledge is simply an act of divine intellect, not a product of the divine will. God is omniscient by necessity of His nature." [Dictionary of Theological Terms, Cairns, 251]

When Jesus was in the wilderness, the fact that the devil came to temp Him was no surprise. He knew it before it was going to happen. God created the world with the plan of salvation in mind. Before the foundation of the world was laid, Jesus had already been crucified. The Lord loves us so much, that He still created the world knowing that we would turn our backs on Him and kill Him. Unlike man who will not set out on a task he knows is gong to fail. Whatever it is we are doing, whether we are saved or not the Lord sees. "For His eyes are on the ways of man, and He sees all his steps." (Job 34:21, NKJV) "And there is no creature hidden from His sight, but all things are naked and open to the eyes of Him to whom we must give account." (Hebrews 4:13, NKJV)

If there is nothing that can surprise the Lord in His own life, then there is nothing in our lives that surprises Him. Hezekiah, a good king of Israel, took a letter from an attacking nation and laid it before the Lord. Though God knew that the nation of Israel was under siege, he still wanted the people to bring Him their concerns. Thought the Lord knows our circumstances, He still wants us to come before Him and lay them at His feet. Just because we are saved does not mean that we benefit from the omniscience of God.
