Daniel wished that people would bless (praise) God"s name forever because of two of His traits particularly. [source][source][source]
"The name stands in Holy Scripture for the nature or revealed character of God, and not a mere label or title. It is found very frequently in the Old Testament as synonymous with God Himself in relation to man.... In the New Testament the same usage is perfectly clear." [1][source]
Daniel mentioned God"s wisdom and power at the beginning and the end of his praise ( Daniel 2:20; Daniel 2:23), and he illustrated both characteristics in between. This entire book clearly reveals God"s wisdom and power. Evidence of His power is His control of events; He changes times and seasons. In other words, He determines when in history events will happen and how long each process or phase of history will last. The second evidence of God"s power is that He controls the destiny of nations; He sets up kings and deposes them. [source][source][source]
"Perhaps the greatest evidence of Yahweh"s lordship in Daniel"s own experience lay ... in his unswerving conviction that his God was the one who appointed and deposed the monarchs of human kingdoms. Because these kings and their subjects thought they were called to their office and given its privileges and responsibilities by their own gods, [2] Daniel"s assertion that the God of Israel was in fact the originator and grantor of human authority was a tacit denial of any perceived role for the gods of the nations." [3][source]
Daniel identified two evidences of God"s wisdom. First, He gives wisdom to the wise; He is the source of all wisdom. Second, He reveals things that would be unknown to humans otherwise. He can do this because He knows what is unknown to people, and the light of knowledge dwells with Him. [source][source][source]
