"That the God of our Lord Jesus Christ, the Father of glory, may give unto you the spirit of wisdom and revelation in the knowledge of him."

"The eyes of your understanding being enlightened; that ye may know what is the hope of his calling, and what the riches of the glory of his inheritance in the saints," (Ephesians 1:17-18)

The "spirit of wisdom" is applied to a wide variety of circumstances. It certainly includes leadership.

But wisdom is also identified with the ability to make beautiful clothing  and to engineer and invent complex equipment. Daniel was said to have "an excellent spirit, and knowledge, and understanding, interpreting of dreams, and showing of hard sentences, and dissolving of doubts." We are even promised that our "adversaries shall not be able to gainsay nor resist."

A "spirit of revelation" is also made available to us. This revelation (literally, "to take off the cover") is not new doctrine or truth. Revelation is implemented by the Holy Spirit, having the source of His revelatory work from Jesus Christ on behalf of Christ.

The Greek language of the phrase "the eyes of |our| understanding being enlightened", could be translated "the vision of your deep thought will be made to shine," or paraphrased in a more colloquial expression, "the light comes on!"
