Musar zu Divrej Hajamim II 6:18

Through humility you will also come to fear God. It will cause you to always think about (Pirkei Avot 3:1) "where you came from and where you are going," and that while alive you are only like a maggot and a worm as after death, and before Whom you will eventually stand for judgment, the Glorious King, as it is written (I Kings 8:27) (Chronicles II 6:18) "Even the heaven and the heavens of heaven cannot contain You" -- "How much less the hearts of people!"(Mishlei 15:11), It is also written (Jeremiah 23:24), "Do I not fill heaven and earth? says the Lord."
