If any of you lack wisdom, let him ask of God, that giveth to all men liberally, and upbraideth not; and it shall be given him.
But let him ask in faith, nothing wavering: for he that wavereth is like a wave of the sea driven with the wind and tossed.
For let not that man think that he shall receive any thing of the Lord.
A double-minded man is unstable in all his ways.

Wisdom comes from God, not from books.  It comes to us through God's Light.  But you have to be a true believer to receive it.
