I'll have to go take another look at that passage, but I am thinking that it refers to the wisdom that God imparts to men--one of His communicable attributes. I don't think it could be referring to the wisdom of the Godhead, for that is incommunicable, and therefore, unattainable by men.

Trust the past to God's mercy, the present to God's love and the future to God's providence." - St. Augustine
