A prayer based heavily on the biblical Book of Daniel, specifically verses 2:20-23, 2:28, 4:2-3, 4:35, and 6:26-27. The wording of the original verses has been generalized somewhat to be more deistic than Jewish or Abrahamic at points, but what results is a simple invocation and praise of God, which I find to be a good one to open up a session of prayer in general focused on the Divine. This prayer was first introduced in this July 2020 post.
O God, may your holy name be blessed forever and ever,
for wisdom and power are yours.
You change all times and seasons, you remove and install all kings;
you give the wise their wisdom and knowledge to those who know;
you reveal deep and hidden things, and you know what is in the darkness.
Light abides with you, and Light comes forth from you.
I adore you and I praise you,
o God of the angels and the prophets,
o Lord of Heaven and Earth,
o Master of the Seen and Unseen,
o you who gives me wisdom and power.
Truly, he is the God of Gods, the King of Kings, the Lord of Lords!
Bless the God of the angels and the prophets, he who is Most High,
the Ever-Living One who reigns forever,
whose dominion is everlasting,
whose kingdom endures throughout the generations,
whose might surpasses the end of time!
None can hold back his hand from acting,
none can challenge his deeds once done!
Praise, exalt, glorify, and bless the King of the All,
whose works are just and whose ways are right,
who humbles those who behave arrogantly,
who relieves those with burdened hearts,
who delivers and saves from perdition,
and who performs signs and wonders in Heaven and on Earth.
