Faith on the other hand is based on that which is unobservable and untestable, any belief beyond the discovery of reason, or as John Locke would say, “where revelation comes into its own is where reason cannot reach. Where we have few or no ideas for reason to contradict or confirm, this is the proper matters for faith. . .being beyond the discovery of reason, are purely matters of faith; with which reason has nothing to do.”
Christianity accepts that God created matter with a finite beginning. Scientists prefer the Big Bang Theory of something from nothing, a supernatural belief not based on direct observation of that which preceded creation. According to the most fundamental law of science, a self-created universe is an unscientific belief, an irrational belief.
If the universe was not created by God, where did it come from? The Law of Conservation of Energy demands that the sum of mass and energy is always constant in any closed system, including the universe; and that without an outside force neither mass nor energy can create itself, nor can mass or energy be destroyed. Mass can be converted into energy, and visa-versa, so mass and energy are limited to interchangeability [E=MC2].
Matter/anti-matter pairs do not self-generate from nothing because they are both composed of positive mass requiring an outside force to bring them into existence, which requires either the energy of creation or, the acceptance that they simply have always existed.
The most basic law of science tells us that outside power is a requirement for the creation of nature’s mass and energy, so we are left with either an eternal God with no beginning and no end who created our finite universe, or we have an eternal uncreated universe with no beginning and no end.
It goes without saying that nobody was or could have been there to observe the beginning of anything whose timeline stretches back into the eternal infinite past, a universe without beginning, except God, the Creator.
While science and reason are both relevant to the universe which can be observed, it is faith, not science or reason, that is relevant to the origin of the universe. Reason is only capable of comprehending the universe, not the origin.
Christianity is based on faith in an eternal God of creation, a belief which is undiscoverable by scientific observation – a belief beyond the discovery of reason.
“The doctrine of a personal God interfering with natural events could never be refuted….by science, for it can always take refuge in those domains in which scientific knowledge has not yet been able to set foot.” Albert Einstein
