Adam Clarke on Psalms 104:1

O Lord my God, thou art very great - The works of God, which are the subject of this Psalm, particularly show the grandeur and majesty of God. The strongest proofs of the being of God, for common understandings, are derived from the works of creation, their magnitude, variety, number, economy, and use. And a proper consideration of those works presents a greater number of the attributes of the Divine nature than we can learn from any other source. Revelation alone is superior.
