"Teenagers think they know everything." It’s something adults say. But it can actually be close to the truth. As teenagers, we look back at our younger selves and see how much we’ve learned. We can be tempted to think-and even say-that we know quite a lot. We figure we’ve got a pretty good grasp on things. Without even realizing it, we have displayed our immaturity. The older and wiser we get the more we realize how much knowledge in the universe we don’t have. Dave Irish, a Christian singer, wrote a song entitled "The More I Learn The Less I Know". Two different lines that strike me as important and relevant are: The more I learn the less I know, with every turn along this road. AND I need Someone to guide me show me the way to go. I believe this is true. The more we learn, the more we realize how little we really know. Thankfully, we do have Someone to guide us–God. While we will always have more to learn, God is omniscient.

Today, I’m going to be explaining the meaning and significance of the omniscience of God. First, what does the fact that God is omniscient mean? The word "omniscient" means "all-knowing". Wayne Grudem, in Systematic Theology, defines the knowledge of God as this, "God fully knows Himself and all things actual and possible in one simple and eternal act." Obviously, God and only God fully knows Himself. 1 Cor. 2:10-11, "The Spirit searches all things, even the deep things of God. For who among men knows the thoughts of a man except the man’s spirit within him? In the same way no one knows the thoughts of God except the Spirit of God.

God knows everything that has actually happened, is happening, and will ever happen. Is. 46:9, "I am God, and there is none like Me. I make known the end from the beginning, from ancient times, what is still to come." God also knows all things possible. Everything that could or could have happened. As Job 37:16 says, God is perfect in knowledge. In addition, God has never learned and cannot learn. If God were ever to learn anything, it would mean He is not eternally omniscient. This point is made using rhetorical questions in Isaiah 40:13-14, "Who has understood the mind of the Lord, or instructed Him as His counselor? Whom did the Lord consult to enlighten Him, and who taught Him the right way? Who was it that taught Him knowledge of showed Him the path of understanding?"

Second, what is the significance of the omniscience of God? Personally, I would find it very heard to trust God if He is not all-knowing. How could I trust Him with my life, my salvation, my eternal future, etc.? I am very grateful that I do not have to worry about that because God is omniscient. As 1 John 3:20 says, "He knows everything." In addition, it is such an awesome thing to realize that God knows me perfectly. Psalm 139:1-4, "O Lord, You have searched me and You know me. You know when I sit and when I rise, You perceive my thoughts from afar. You discern my going out and my lying down; You are familiar with all my ways. Before a word is on my tongue You know it completely, O Lord."

In conclusion, we have looked at the meaning of the omniscience of God and seen that He is all-knowing. And finally, what a comforting thing to know that nothing catches God by surprise and that He is familiar with all of our ways!
