Space and time are a function of mass (matter). If there were no particles in our universe that had the characteristics of matter, there would be no space-time.
As creatures composed of matter and trapped in a space-time continuum, limited to this universe, it would seem that the only truths that we might discover are limited as well, and our perspective, subject to the physics of matter. Beyond this we have no knowledge except that which is given to us by our Father who is God.
Many do not accept the existence of God and deride such belief as naive and insecure. But, in truth, they have limited their horizons with self-generated clouds, born of their blind skepticism.
Yes, we should be observer of data. Yet, to declare spiritual data to be false because it originates from a source that we cannot measure with our material faculties is reckless.
"I have seen the business that God has given to the sons of men to be busy with. He has made everything beautiful in its time; also he has put eternity into man's mind, yet so that he cannot find out what God has done from the beginning to the end."
"He who made the Pleiades and Orion, who turns blackness into dawn and darkens day into night, who calls for the waters of the sea and pours them out over the face of the land -- the LORD is his name."
(the above is a paraphrase from something I read this morning, except scriptural quotes)
