Faith is a funny thing. The writer of Hebrews writes "Faith shows the reality of what we hope for; it is the evidence of things we cannot see." (NLT) That's like looking into the future, and saying that something is definitely going to happen, while everyone else says maybe it will, and maybe it won't.
Then to give further insight, he lists several examples, to act as pictures of what faith looks like.
The first example concerns creation. Some people say God spoke, and out of nothing -- no matter, no energy, not anything -- brought into being everything that is. And some people say there was a bunch of stuff, and either the stuff exploded, or the stuff crashed to together, and the resulting "mish mash" resulted in everything that is, purely by chance.
Which makes me want to ask the question: where did the stuff come from? Seems to me, some people believed there was stuff, that there was an explosion -- as the result of a collision, or the result of an internal reaction -- and the got rearranged in some way that it generated light, water, an oxygen rich atmosphere, and finally, life. Sounds to me like evidence of things we cannot see. Sounds to me like faith.
No one was there in the beginning to witness how it happened. People, the world, and the universe exist. So, they got here somehow. But no one really knows how. They can only theorize how, and believe one of the theories.
And it cannot be a scientific theory. The scientific method requires an observation, a theory, and a test, or experiment, that demonstrates the truth of the theory. And the experiment can be repeated a million times, and get the same results. Can we repeat exploding a bunch of matter, and the universe, and all of life is created? I am sure that someone has tried on a small scale to repeat the big bang creation. But no matter which system, creation must be understood, and accepted, by faith.
====================
I will probably look at all the examples myself. I don't know if I will share my thoughts about all of them here. I will certainly share several of them.
