That is the foolishness of spiritual infancy. It also means trusting others on issues to the extent of their reliability. The goal that we are to aim for is to live in relationships that can handle complete transparency. At times, that may even mean being vulnerable toward another for the sake of communicating love, paying a price to reach out with healing grace. But, in all things, wisdom must deal with reality, by balancing these four important practical principles.
Wisdom is always practical, because wisdom is problem orientated.
Knowledge tells us 'what' and wisdom tells us 'how'. Knowledge without wisdom is like a gold ring in a pig's snout. For this reason, the answer to a problem is invariably found in the problem itself. A piece of history from the Bible illustrates these four principles, and how the answers to life's problem's are composed of the constituents of those problems. Nothing could prevent it, not even the emperor himself, for a law of the Persian empire when once signed could not be revoked even by the ruler who issued it.
