God's meaningful universe

John Frame in his book, The Doctrine of God, explains the significance of decrees and the job of humanity in understanding them.

God's decrees display his lordship attributes. In an obvious way, they display his control, for they are efficacious and universal. God's intentions will certainly be fulfilled, and they will be fulfilled for everything in the created world.

They also display his authority, for they are meaningful thoughts--wise plans or counsels for the world. As such, they interpret the world; they determine the meaning and significance of everything God makes. God's interpretations, of course, are always supremely authoritative. When he declares the significance of something for his purpose, that is the significance it has. So the doctrine of the decrees implies that God has authoritatively preinterpreted everything and every event. As Van Til emphasized, the interpretation of the facts precedes the facts. Our world is a world that is exhaustively meaningful, because it is the expression of God's wisdom. Among human beings, interpretation is not the work of trying to assess for the first time the significance of uninterpreted facts. Rather, ours is a work of secondary interpretation, interpreting God's interpretation. (pp. 316-317)

In theology, the universe is not random. The events and created objects are purposely created by God to declare His glory (Psalm 19:1-2) and His wrath (Romans 1:18) to anyone who will listen, and we all will listen one day. For those who love God, these facts express God's omnipresence and omnipotence and thus bring comfort and joy.
