This is certainly not how the Bible defines faith. Good faith, according to the Bible, like good science, needs sound, rational thinking. Christianity is based in presuppositions combined with evidences, not in blind beliefs. In John 17.8 (also Jn. 14.11) we learn that faith is a judgment of certainty based on the evidence. Hebrews 11.1 confirms it. "Now faith is being sure of what we hope for and certain of what we do not see." There’s no absence of evidence here. The word for "being sure of" is ὑπόστασις (hupostasis). It is defined as "assurance; what stands under anything (a building, a contract, a promise); substantial nature; essence, actual being; reality (often in contrast to what merely seems to be); confidence; conviction; steadfastness; steadiness of mind." "The steadfastness of mind which holds one firm." The term is common in ancient business documents as the basis or guarantee of transactions. There's nothing wobbly or blind here. It's not just confidence or optimism, but a guarantee. It's a real knowledge.
Belief is always a choice, and is always based on evidence. When you sit down in a chair, you didn’t think twice about sitting down. You believe that the chair will hold you. Faith? Yes. You've sat in chairs hundreds of times, but you can't be absolutely sure it will hold you this time. Things do break on occasion. But you make an assumption of truth based on enough evidence to make it reasonable for you to make that assumption, and you sit down. That's faith, and it was a conscious choice based on a reasonable body of evidence.
Almost all of life works this way because we can never know what lies ahead. Every time you turn a door knob you are expressing faith, because 10,000 times you've turned a door knob, and it opened the door. So you turn the knob and move forward. Does it always work that way? No. Sometimes you turn the knob and the door doesn't open. But you make an assumption of truth based on enough evidence to make it reasonable for you to make that assumption, and you walk forward in faith.
We know chairs hold people. That's past experience and learning. We know turning door knobs open doors. We know that when we turn a key a car starts. But every time we turn a car key, we do it because we believe it will start. The evidence is compelling, and it was a conscious choice. We don't know for sure that the car will start, and unfortunately sometimes it doesn't. Then we use our knowledge to try to figure out what to do about it. We dial our phone (as an act of faith, assuming it will work and help us reach another person), and try to get help.
I can only stand by faith on evidence, reason, and knowledge about things that haven’t happened yet, just like the chair, key, and doorknob. But I can make an assumption of truth about God and my Christian belief based on enough evidence to make it reasonable to make that assumption. And again, what we’re talking about is inferring the most reasonable conclusion.
Hebrews 11.1 also says we can be sure of what we hope for (what is still future). Faith is more than optimism, and it's more than wishful thinking. Faith is knowledge, pure and simple. But faith understands there are different kinds of knowledge. Some knowledge is because of what I've already experienced (I know I had Cheerios for breakfast), and yet other knowledge is because of evidence, even though I haven't seen (my getting in the car and heading to the store, "knowing" it is there).
The verse continues: "…and certain of what we do not see." The word for "certain of" is ἔλεγχος (elegchos). It means "proof; proving; conviction; being sure of." At what point did people get the idea that Christian faith is an absence of evidence? The faith of the Bible is distinctly evidentiary and based in knowledge. God never asked anyone to believe in Him without first giving some kind of evidence. Whether it is Abraham, Moses, David, Daniel, Jesus, Paul, or anyone else in the Bible, evidence precedes faith. God spoke to Abraham, appeared to Moses in a burning bush, performed miracles for Pharaoh, strengthened David in the killing of Goliath, and on and on. Jesus performed miracles, taught, and healed people before He ever asked that people believe in him.
