One of Satan's greatest accomplishments has been to convince us that faith is binary and even the tiniest bit of doubt taints faith beyond redemption.
My belief is that most people believe in something called "science". Would we discard "science" as cavalierly as we toss "faith"?
Do you believe quarks exist? If you really believe in science than you must 100% believe in quarks. How can you believe in quarks if you never saw them? I think you are lying when you say you believe in quarks.
OK, if you REALLY believe in quarks then you can name all six flavors of quarks.
For those of you who are now convinced you are doomed to science hell, the six flavors are up, down, strange, charm, bottom, and top.
But don't worry, since you don't believe in science you are not subject to the rules of science. You can fearlessly jump off tall buildings, poke holes in your aorta, consume organophosphates in abundance and provoke red-heads without fear.
How much do you believe in science? If pressed, you would probably agree that it is a handy way to grip the universe even if you are not conversant in every detail of what is commonly called science.
How much faith do you give yourself credit for? Faith is a handy way to grip the parts of the universe that are opaque to science. Even more, Faith as expressed in the first five books of the Bible is a handy way to grip the dynamics of arch-type small, closed groups. Faith as expressed in the New Testament is a handy way to grip the dynamics of larger, more porous groups.
I am a simple guy. Using science as an analogy, my faith is not a Large Hadron Super Collider. It is a 12" adjustable wrench. What it lacks in sophistication it makes up for in versatility.
Yes I have doubts. No, my faith is not perfect. But neither is the wrench pictured above.
