Even if we know a lot, we don’t know much, at least not in comparison to God. Psalm 147 is a Psalm of Praise from beginning to end. In verse 5, the Psalmist exalts the knowledge of God, His omniscience.
God knows Himself. We know what God has revealed about Himself. As worshipers, we spend our lives learning about Him. We will do so for eternity!
God knows all there is to know. There is nothing outside of His knowledge, and nothing is hidden. This brings comfort into the life of the believer because we rest in the God who is never taken by surprise. This also brings a holy fear and reverence into the life of the believer, because nothing in our lives is hidden from Him.
God’s knowledge, and His sovereign will and providence, work in tandem. God is bringing all of creation to a desired conclusion. He will usher in a new heavens and a new earth. We cannot know or understand everything that is going on, or how God is working to bring this about but we trust that He is.
As finite human beings, there are many limitations on what we know. We hardly have a good understanding of even the times we live in. Much less the times that have passed or the times that will come. Pride causes us to exalt ourselves and think that we know a lot. The more we learn and are educated, formally and informally, tends to cause us to think we have arrived. The reality is, the more we learn, the more we understand there is to know.
The most important focus of what we know, and can know, must be on God. Our understanding of Him impacts all of life. It brings everything else into focus.
This leads to exaltation! This was the conclusion of the Psalmist- Great is our Lord and abundant in strength; His understanding is infinite.
