Psalm 99

God is a great and mighty ruler. His reign is over all that is seen. He is king even over that which dwells in the depths of the sea. If we were to focus exclusively on his majesty and power we would fall into the same state as the people and earth mentioned in verse 1; fearful. But the end of the psalm offers us a view of God that brings balance to his nature; he is holy. This does not just indicate his seperation from the sinfulness of the world. God's holiness indicates his natural bent toward gracious loving-kindness. His holiness points him toward all people with an unquenchable love and passion for fellowship with us. 
It took me about 1 minute to read this psalm.
