"So unbelievable things like that happen. But you have to believe it first. Not wait until you see it first, then touch it, then believe it... You say it from the heart.”

Wallace Black Elk  Lakota

Everybody nowadays, believes in scores of assumptions for which there is good evidence, but no perfect visual proof. And does not science demonstrate that visual proof is the weakest proof? It is being constantly revealed, as mankind studies the material world, that outward appearances are not inward reality at all.  To illustrate:

The prosaic steel girder is a mass of electrons whirling around each other at incredible speed. These tiny bodies are governed by precise laws, and these laws hold true throughout the material world. Science tells us so. We have no reason to doubt it. When, however, the perfectly logical assumption is suggested that underneath the material world and life as we see it, there is an All Powerful, Guiding, Creative Intelligence, right there our perverse streak comes to the surface and we laboriously set out to convince ourselves it isn’t so.

We can only clear the ground a bit. If our testimony helps sweep away prejudice, enables you to think honestly, encourages you to search diligently within yourself, then, if you wish, you can join us on the Broad Highway. With this attitude you cannot fail. The consciousness of your belief is sure to come to you.

Great Spirit give us strength to believe.
