What is your faith? Some of my atheist friends will say, “I don’t have a faith,” but that isn’t true. The definition of faith given in the Bible is, “…faith is the substance of things hoped for, the evidence of things not seen.” (Hebrews 11:1). The Greek word used for “substance” in this verse is “hupostasis” which is from two words meaning “stand” and “upon.” It is literally our “foundation.” What is your foundational faith?
Each of us has things in our lives that are fundamental to our existence and that we trust even though we don’t see them. We all have faith in gravity. We don’t sit around worrying about whether gravity will suddenly fail and we will drift off into outer space. There is a vast list of things that we cannot see and yet which are foundational to our existence.
For most of us, our foundational faith has more to do with our intellectual understandings, our values, our morals, and how we make decisions. The book of Hebrews identifies some of those things with scientific accuracy and on which most of us can agree. Verse 3 says, “By faith we understand that the universe was formed … so that what is seen was not made of what was visible.” Whether you are a Christian or an atheist, you can have faith in that part of the verse. However, the middle of that verse says, “…was formed at God’s command…” An atheist would disagree that God had anything to do with it but would still agree that “…what is seen was not made of what was visible.”
That raises an important point. Is faith something that is blind? The answer is clearly “no!!” We have faith in gravity because, for all our lives, gravity has functioned in the same way. We trust gravity and have faith in it because we have seen it working. We cannot directly see that God commanded the formation of the cosmos. Having faith in the cause of the universe requires a different kind of evidence. We cannot directly observe the creation of time, space, matter/energy, and life.
Science gives us interesting examples of faith in something we can’t directly see. For many years, scientists debated whether light was a wave or a particle. Those scientists with faith that light was a wave had evidence for their faith. They proved it by showing destructive interference in light. Two light waves can intersect and cancel each other out, leaving darkness. Waves can cancel each other, but particles cannot. Experiments also show that waves can be polarized, and particles cannot. You can shine a light through certain types of crystals, and the crystals will only allow light vibrating in one plane to pass through. Reflected light turns out to be polarized, as you know if you have a pair of Polaroid sunglasses. There was massive evidence that light is a wave, and 400 years ago, that was the faith of most scientists.
The problem with that faith was that there were things that light could do that waves could not do. Light could shine on certain materials and knock electrons out of those materials. This is called the photoelectric effect, and we all use it in photo-sensors and solar-cells. Waves such as sound waves cannot go through a vacuum because they need something to “wave.” Particles can go through a vacuum. Some scientists had such strong faith that light was a wave they explained how light reaches us from the Sun by saying that space is not a vacuum. They made up a substance they called “aether” which they said filled the universe and which waves could pass through.
Scientists today have faith in the dual nature of light. It is both a wave and a particle, and aether doesn’t exist. The point is that our faith can change when we see new evidence. What is your foundational faith, and how has it changed during the last few years? If you are a Christian, has your faith grown? We’ll talk about that tomorrow.
