Many people incorrectly think of faith as a general property. They say, “I have faith,” or “he is a faithful person.” In reality, faith is a process. It is a tool that can be applied to any topic, situation, outcome, level of knowledge, object of desire, or depth of desire. For example, faith is always exercised at the level of particular beliefs, and beliefs are specific. Beliefs can explain one or very many things, but each and every belief must take the form of a mapping of specific causes and specific effects.
When you exercise faith in a belief, you will either find yourself proving your belief by receiving the intended outcome or you will find yourself revising your understanding of the belief so as to bring it into accordance with new information you have learned in the process.
