O LORD, You have searched me and know me. You know when I sit down and when I rise up; You understand my thoughts from afar. You scrutinize my path and my lying down, and are intimately acquainted with all my ways. Even before there is a word on my tongue, behold, O LORD, You know it all. You have enclosed me behind and before, and laid Your hand upon me. Such knowledge is too wonderful for me; it is too high, I cannot again it. (Psalm 139:1-6)
In beautiful and picturesque language, David praises God in this psalm for His omniscience. God knows all things past, present, and future. There is nothing He doesn’t know. What is hidden from human sight is known by God. He sees all and knows all, in other words.
All of God’s attributes give us comfort, convict us, challenge us, and cause us to praise Him.
God’s omniscience should comfort us. He knows all there is to know, so He’s not “in the dark” about anything. The Lord knows all the facts about every circumstance and situation. He knows what we’re going through. He knows what we’re thinking and feeling. He’s aware, in ways we can’t begin to understand, of what are brothers and sisters in Christ in Syria are experiencing. We can never say “God doesn’t know.” He does! That He is “intimately acquainted” ought to give us great comfort.
God’s omniscience should convict us. God knows everything, which includes our sins whether they are in thought, word, deed, attitude, or motive. He knows when fallen short of His glorious perfection, even if no one else does. There isn’t anything, no matter how small, that can be hidden from God. He knows everything about me including my sin – I can’t hide it from Him.
God’s omniscience should challenge us. Although omniscience is not a communicable attribute of God (meaning that we can’t completely reflect it), w can imitate it to a certain extent. Because God knows all things, knowledge is possible and important. Being a ‘know-nothing” or ignorant is not bliss. We should strive to know all we can about as many subjects as we can because we reflect God’s character trait of omniscience when we do.
God’s omniscience should cause us to praise Him. Think about – God knows absolutely everything! Consider how much there is to know in the universe and we might just begin to have some idea of how infinite the One who knows it all is. The fact that God knows all things makes Him worthy of praise. “Oh, the depth of the riches both of the wisdom and knowledge of God” (Rom. 11:33)!
