What does the Bible mean when it uses the word “faith”?

8 Comments

From Tektonics.

Here’s a popular view of faith that says that people believe weird things by acts of will:

Consider these three views:

  1. A “faith healer” named Benny Pophagin offers to heal Joe of his lumbago. Benny lays hands on Joe and prays, but the lumbago remains. Benny waves Joe away, saying, “This is your problem. You don’t have enough faith.”
  2. A Christian faces several objections to his beliefs that he cannot answer. He says, “I don’t care what people say, I still have faith.”
  3. The famous skeptic Mark Twain said, “Faith is believing what you know ain’t so.”

Can anyone guess what is wrong with this picture?

The answer is that all of these examples offer an incorrect definition or understanding of what Biblical faith is all about. Twain’s own definition does correctly (with some negative emphasis) embody the way “faith” is understood by far too many today — but it does not match the Biblical definition of that word, and as the first two examples suggest, “faith” is a badly misunderstood concept in the church at large.

Atheists and many Christians seem to agree on that view of faith… but is that view Biblical?

Here’s an excerpt from the article showing the Biblical view of faith:

The Greek word behind “faith” in the NT is pistis. As a noun, pistis is a word that was used as a technical rhetorical term for forensic proof.

Examples of this usage are found in the works of Aristotle and Quintiallian, and in the NT in Acts 17:31:

Because he hath appointed a day, in the which he will judge the world in righteousness by that man whom he hath ordained; whereof he hath given assurance unto all men, in that he hath raised him from the dead.

If you are used to thinking of “faith” in terms of our first two examples, this will assuredly come as a surprise. The raising of Christ is spoken of here as a proof that God will judge the world. However, if we think about the missionary preaching of the book of Acts, this makes perfect sense and teaches us a certain lesson.

Here is more food for thought: Is there anyplace in the NT where we can find someone giving their “personal testimony”?

The answer is yes — but it is in Phil. 3, where Paul gives his personal testimony about his former life, when writing to fellow Christians. He does not use it in a missionary setting to unbelievers.

Indeed, one will find nowhere in the NT an example of missionaries, or anyone, giving their personal testimony.

This is for good reason. The ancients conceived of personality as static; the way you were born is the way you stayed. Personal change was not a focus, because it was thought impossible. This is why the church remained suspicious of Paul even after his conversion, and until Barnabas (who probably knew Paul previously) testified on his behalf.

But note well: The following is not the sort of thing one will find in the NT:

Acts 2:48-52 And Peter arose and said, Men and brethren, I testify to you that whereas I formerly smoked mustard leaves, drank wine, cursed daily, and smelled moreover of fish, when the Lord Jesus Christ entered my heart I became clean. Now I no longer smoke, I no longer drink, my language is no longer filthy, and I bathe daily. Praise the Lord!

On the contrary.Here is what we do find in the missionary preaching of the NT:

Acts 2:22-36 Ye men of Israel, hear these words; Jesus of Nazareth, a man approved of God among you by miracles and wonders and signs, which God did by him in the midst of you, as ye yourselves also know: Him, being delivered by the determinate counsel and foreknowledge of God, ye have taken, and by wicked hands have crucified and slain: Whom God hath raised up, having loosed the pains of death: because it was not possible that he should be holden of it. For David speaketh concerning him, I foresaw the Lord always before my face, for he is on my right hand, that I should not be moved…Men and brethren, let me freely speak unto you of the patriarch David, that he is both dead and buried, and his sepulchre is with us unto this day. Therefore being a prophet, and knowing that God had sworn with an oath to him, that of the fruit of his loins, according to the flesh, he would raise up Christ to sit on his throne; He seeing this before spake of the resurrection of Christ, that his soul was not left in hell, neither his flesh did see corruption. This Jesus hath God raised up, whereof we all are witnesses. Therefore being by the right hand of God exalted, and having received of the Father the promise of the Holy Ghost, he hath shed forth this, which ye now see and hear… Therefore let all the house of Israel know assuredly, that God hath made that same Jesus, whom ye have crucified, both Lord and Christ.

Peter’s primary appeal here was threefold:

  1. He appealed to the evidence of the wonders and signs performed by Jesus;
  2. he appealed to the empty tomb,
  3. and he appealed to fulfillment of OT prophecy.

In short, his appeals were evidentiary. One of course might wish to dispute the validity of the evidence, but in context this is beside the point. The point is that Peter grounded belief in Christianity on evidence — or, as the definition of pistis in Acts 17:31 would put it, proofs.

If Paul and Peter would around today, Paul would have a Ph.D in Astrophysics (Romans 1) and Peter would have a Ph.D in Ancient History (Acts 2). And they would be using good theistic arguments to defend belief in God, and historical evidence to defend the resurrection. Because Christianity is all about the evidence. Always has been, always will be. We do not offer Christianity to people on the basis of feelings or life enhancement. It is true, and that’s all.

Here is my article on whether the Bible opposes logic and evidence. And one about why some (weird) Christians don’t defend their faith.

UPDATE: Michael sends me this video from Greg Koukl:

And notes that Greg Koukl has a new book coming out soon, called “Faith is Not Wishing”. Greg Koukl formed my views on what faith is, along with R.C. Sproul and J.P. Moreland. For now, you can read this article about faith by Greg Koukl, and it’s FREE.

Is Skeptic magazine keeping up with the progress of science?

Leave a comment

Not if the progress of science undermines the speculations about a naturalistic origin of life. In their latest issue, Skeptic magazine espouses the old, discredited Miller-Urey experiments from half a century ago. The old science is Darwin-friendly. But is that old science still current?

Consider this post from Evolution News.

Excerpt:

Stanley Miller had not in fact “simulated atmospheric conditions on the early Earth.” And this has been known for quite a long time. Origin of life theorist David Deamer states:

This optimistic picture began to change in the late 1970s, when it became increasingly clear that the early atmosphere was probably volcanic in origin and composition, composed largely of carbon dioxide and nitrogen rather than the mixture of reducing gases assumed by the Miller-Urey model. Carbon dioxide does not support the rich array of synthetic pathways leading to possible monomers . . . .

(D.W. Deamer, “The First Living Systems: a Bioenergetic Perspective,” Microbiology and Molecular Biology Reviews, Vol. 61: 239 (1997).

As I discuss here, there’s very good reason to understand why an atmosphere on Earth of volcanic origin would not contain methane or ammonia. A 2010 paper in Cold Spring Harbor Perspectives in Biology states that the chemical properties of the Earth’s mantle have not changed over time, and thus if volcanoes don’t produce appreciable amounts methane and ammonia today (which they don’t), then they also wouldn’t back then:

Geochemical evidence in Earth’s oldest igneous rocks indicates that the redox state of the Earth’s mantle has not changed over the past 3.8 Gyr (Delano 2001; Canil 2002).(Kevin Zahnle, Laura Schaefer, and Bruce Fegley, “Earth’s Earliest Atmospheres,” Cold Spring Harbor Perspectives in Biology (2010).)

The papers cited in the quote above confirm this point. For example, Canil’s 2002 paper in Earth and Planetary Science Letters found that vanadium redox states in peridotite-bearing mantle xenoliths and Archean cratons imply that Earth’s mantle was just as oxidized in the Archean as it is today. The paper concludes:

Abiotic synthesis of molecules and hydrocarbons that can lead to life in early Archean mantle-derived volcanic gases requires they contain significant H2 and CO, but such reduced components are not supported by results of this and many other studies, which imply a scenario of Archean mantle redox not unlike that of today. Life may have found its origins in other environments or by other mechanisms.

(Dante Canil, “Vanadian in peridotites, mantle redox and tectonic environments: Archean to present,” Earth and Planetary Science Letters, Vol. 195:75-90 (2002) (internal citation removed).)

The situation is summed by authorities Kasting and Catling as follows: “For the 4 billion years for which a geological record exists, no evidence for a pronounced change in mantle redox state exists.” (James F. Kasting and David Catling, “Evolution of a Habitable Planet,” Annual Review of Astronomy and Astrophysics, Vol. 41:429-463 (2003).)

Skeptic magazine cannot be skeptical on the origin of life. They have to affirm a naturalistic origin of life, because they assume that there was no intelligent cause of the origin of life, before looking at the evidence. They affirm that the universe is eternal, before looking at the evidence. They affirm that there is a multiverse to explain the fine-tuning, before looking at the evidence. They affirm that habitable planets are common, before looking at the evidence. They assume that a gradual string of pre-Cambrian fossils exists, before looking at the evidence. They believe in man-made catastrophic global warming alarmism, before looking at the evidence. Evidence is very, very bad for skeptics. Which is why they oppose the progress of science and have to go back fifty years to the speculations. They don’t like the progress of science. They believe what they want to believe. And that’s why they don’t want to debate anything, but instead refuse to hire people who disagree with them – or fire them if they are already hired.

It’s Skeptic magazine versus the scientists. Religion versus science. The pre-supposition of naturalism versus reality.

Scientists discover that tides affect a planet’s habitability

Circumstellar Habitable Zone
Circumstellar Habitable Zone

Science Daily reports on a new factor that affects planetary habitability: tides. Specifically, tides can affect the surface temperature of a planet, which has to be within a certain range in order to support liquid water – a requirement for life of any conceivable kind.

Excerpt:

Tides can render the so-called “habitable zone” around low-mass stars uninhabitable. This is the main result of a recently published study by a team of astronomers led by René Heller of the Astrophysical Institute Potsdam.

[…]Until now, the two main drivers thought to determine a planet’s temperature were the distance to the central star and the composition of the planet’s atmosphere. By studying the tides caused by low-mass stars on their potential earth-like companions, Heller and his colleagues have concluded that tidal effects modify the traditional concept of the habitable zone.

Heller deduced this from three different effects. Firstly, tides can cause the axis of a planet`s rotation to become perpendicular to its orbit in just a few million years. In comparison, Earth’s axis of rotation is inclined by 23.5 degrees — an effect which causes our seasons. Owing to this effect, there would be no seasonal variation on such Earth-like planets in the habitable zone of low-mass stars. These planets would have huge temperature differences between their poles, which would be in perpetual deep freeze, and their hot equators which in the long run would evaporate any atmosphere. This temperature difference would cause extreme winds and storms.

The second effect of these tides would be to heat up the exoplanet, similar to the tidal heating of Io, a moon of Jupiter that shows global vulcanism.

Finally, tides can cause the rotational period of the planet (the planet’s “day”) to synchronize with the orbital period (the planet’s “year”). This situation is identical to the Earth-moon setup: the moon only shows Earth one face, the other side being known as “the dark side of the moon.” As a result one half of the exoplanet receives extreme radiation from the star while the other half freezes in eternal darkness.

The habitable zone around low-mass stars is therefore not very comfortable — it may even be uninhabitable.

Here is my previous post on the factors needed for a habitable planet. Now we just have one more. I actually find this article sort of odd, because my understanding of stars was that only high-mass stars could support life at all. This is because if the mass of the planet was too low, the habitable zone wouldbe very close to the star. Being too close to the star causes tidal locking, which means that the planet doesn’t spin on its axis at all, and the same side faces the star. This is a life killer.

This astrophysicist who teaches at the University of Wisconsin explains it better than me.

Excerpt:

Higher-mass stars tend to be larger and luminous than their lower-mass counterparts. Therefore, their habitable zones are situated further out. In addition, however, their HZs are much broader. As an illustration,

  • a 0.2 solar-mass star’s HZ extends from 0.1 to 0.2 AU
  • a 1.0 solar-mass star’s HZ extends from 1 to 2 AU
  • a 40 solar-mass star’s HZ extends from 350 to 600 AU

On these grounds, it would seem that high-mass starts are the best candidates for finding planets within a habitable zone. However, these stars emit most of their radiation in the far ultraviolet (FUV), which can be highly damaging to life, and also contributes to photodissociation and the loss of water. Furthermore, the lifetimes of these stars is so short (around 10 million years) that there is not enough time for life to begin.

Very low mass stars have the longest lifetimes of all, but their HZs are very close in and very narrow. Therefore, the chances of a planet being formed within the HZ are small. Additionally, even if a planet did form within the HZ, it would become tidally locked, so that the same hemisphere always faced the star. Even though liquid water might exist on such a planet, the climactic conditions would probably be too severe to permit life.

In between the high- and low-mass stars lie those like our own Sun, which make up about 15% percent of the stars in the galaxy. These have reasonably-broad HZs, do not suffer from FUV irradiation, and have lifetimes of the order of 10 billion years. Therefore, they are the best candidates for harbouring planets where life might be able to begin.

This guy is just someone I found through a web search. He has a support-the-unions-sticker on his web page, so he’s a liberal crackpot. But he makes my point, anyway, so that’s good enough for me.

Maybe the new discovery is talking about this, but I already knew about it because I watched The Privileged Planet DVD. Actually that whole video is online, and the clip that talks about the habitable zone and water is linked in this blog post I wrote before.
