I've been reading through the Deutero-canon lately. Some people refer to these books as the "Apocrypha." One such book is the Wisdom of Solomon or Wisdom for short. The theme of the book is the greatness of wisdom. There is one passage (chapter 9) where the author prays for wisdom explicitly. The passage offers a wonderful template for ways we can beseech God for wisdom.
It begins with a reflection on the character of God.
