2 Cor 10:5We destroy arguments and every lofty opinion raised against the knowledge of God, and take every thought captive to obey Christworking-1229720-1279x977

Previously, I took a great deal of time to show that not only does objective truths exist, but that we can reasonably approach and assess truth in many important areas of philosophy, theology, history, and science. Confidence in our knowledge in these areas can be gained and increased by careful reasoning and critical thinking through argumentation. Having laid the philosophical foundations to justify the use of these tools, I now want to apply them towards our knowledge of God.

Can Truths About God Be Known?

Rom. 1:20“For his invisible attributes, namely, his eternal power and divine nature, have been clearly perceived, ever since the creation of the world, in the things that have been made. So they [unbelievers] are without excuse.”

But first, perhaps it would be appropriate to say a few words addressing the question, can truths about God be known? Is God too “other” for finite humans to comprehend or in any way grasp His properties? One agnostic trend makes the claim that this is impossible. Paul, in Romans 1 indicates that some amount of knowledge about God is indeed possible through observation and reflection. I think the agnostic claim itself fails philosophically as an absolute claim, as it claims to have knowledge of God, namely that knowledge about God is unattainable. So what is gained by the destruction of this claim? Well, we can escape the prison of ignorance concerning God; it seems that it is not logically impossible to know something about God (if He exists). This, of course, doesn’t take us very far towards positive knowledge claims about God, but it does make forward progress possible, at least in principle.

Baby Steps

In the posts that follow, I want to move, with slow and careful steps, through some arguments that have installed in me confidence that God exists and is accurately reflected in Christian theism as laid out in the Bible. Slow and careful, I say, because these are not philosophical word games, some smoke-and-mirrors rhetorical trick. I’m not going to try to take you all the way from skepticism to true believer all in one argument, as that seems an awful lot to ask from one argument [1]. Instead, I want to build a cumulative case for you that grows in stages from previous groups of arguments, as laid out in my earlier post about the goals of Christian case making. As a reminder, here is the model I’m following in this method.

                      | Has God spoken? |

                |        Has God acted?         |

     |                     Does God exist?                 |

|    Does Truth exist? Is Truth knowable?         |

We have completed step one, concerning Truth, and are now moving up to the next step, “Does God exist?” The arguments will not, as I said, make the full case in one step, but will move us forward, bit by bit, with evidence for God’s existence, His attributes, and how Christian theism seems to fit best with reality and history among other religions. I think this careful case-building strategy can be persuasive, as the Holy Spirit softens the heart and removes hostility towards God. Overthrowing one’s worldview in favor of one very different is no small matter, and one which I would expect not to happen quickly.

Please join me next time as we begin with arguments for God’s existence, and I hope that you will have your confidence and trust strengthened in the truth of the Bible as we see how reality truly is reflected, described, and prescribed. I certainly found it convincing, and I pray you will too.

Faith and Reason, Part 2

In my last post, I hopefully clarified the difference between biblical faith and the contemporary understanding of that word. Often, it seems to be put in opposition to reason, and it was my goal handshaketo show they are complimentary, not opposites.

What is Reason?

First, I want to make some important distinctions. We will be talking about argumentation here in our discussion of reason, and this word often has some bad associations because of the way we use it. When my kids are in the back seat of the van being nasty to one another with their words, I might finally yell back to them, “Stop with the arguing already!” But I want to use the concept of arguing in a different way here. So here’s what I don’t mean: arguing and reason is not quarreling, bickering, squabbling, or contradiction. It is also not judgmental, narrow-minded arrogance.

When we have a verbal interaction with someone, it usually takes on one of these four forms: [1]

  1. Discussion – A discussion is where people are sharing information and opinions with one another.
  2. Disagreement – Disagreements happen when people have conflicting opinions, but are not trying to change the other’s mind about it.
  3. Argument – People with differing opinions are now giving reasons to support their beliefs in order to persuade the other.
  4. Fight – Name-calling, insulting, and other nastiness happens in a fight; it is abusing the other person and not giving reasons at this point.

I love this classic Monty Python skit to illustrate:

Reason is a tool by which we evaluate observations to form conclusions about reality; it is working out what follows from what and evaluating the relationship between real and possible objects and other real and possible objects. This often involves others, challenging ideas and being challenged; this is argument, part of loving the Lord with all your mind (Mark 12:30). Arguing well is a good thing, as it helps us distinguish truth from error.

Is Faith Opposed to Reason?

If you say yes, then your view of the relationship between faith and reason looks something like this:

FvR2 FvR1

As one grows, the other shrinks: the more evidence and reason one has, the less need for faith, until it is eventually all squeezed out. Conversely, one with “perfect faith” then has no doubts and no need for logic and reason.

But, as I pointed out in my last post on faith, this isn’t a picture of biblical faith at all. Instead, it is more accurately illustrated this way:


In reality, the more evidence and reasons we have concerning the trustworthiness of a thing or proposition, the more trust or faith we place in it. This is biblical faith and the true model of the relationship between faith and reason.

In the next post, I will talk more logic and putting together your toolbox for clear and critical thinking.

What is Truth? Part 2

In my last post, I explained a bit about the nature of truth, and then investigated some of the distortions of truth. Today, I want to go to the next step and discuss the way we apprehend truth, ioana-1435161answering the question, “What is knowledge?

Knowledge is most commonly defined as Justified True Belief (or the JTB model), and each one of these words represent a crucial component of knowledge. Let’s consider each in turn, in reverse order:


Belief is required for knowledge. It would be exceedingly strange if I made the statement, “I know that it is snowing outside, but I don’t believe it.” Does it make any sense to claim to have knowledge of something that we don’t believe? (We’ll assume that by “I don’t believe it” I’m not just meaning that I’m surprised about it.)


Truth is required for knowledge. Again, it would be very odd for me to say, “I know it’s snowing outside, but it’s not true that it’s raining outside.” Can I have knowledge that something is happening when it is not truly happening? I think we’ll have to agree not.


Justification is required for knowledge. Consider the situation in which I said, “It is raining outside,” and I believe it, and it happens to be true, but it was just a lucky guess. Perhaps I had been inside all day away from windows or any other external clues concerning the weather. Can I truly claim to have knowledge? No, not without justification.

Justification concerns reasons and evidence that give confidence that our answers are not mere guesses or dumb luck, but actual knowledge. It’s not “I hope it’s true” or “I think that it’s true,” but “I know that it’s true.” This is an important part of Christian evangelism, as demonstrated by author Christian Smith in his book Soul Searching in which he reports that students who grew up in Christianity who had since abandoned belief said they did so because of “intellectual skepticism and doubt.” These students had beliefs, and they were true, but they had no justification for those beliefs. They needed to know why they believe, not just what.

Knowledge is essential for spiritual transformation. Consider Romans 12:2 – “Do not be conformed to this world, but be transformed by the renewal of your mind, that by testing you may discern what is the will of God, what is good and acceptable and perfect.” We need to be able to have knowledge of the good, acceptable, and perfect will of God.

Apologetics can provide justification, which turns true belief into confident knowledge. This also helps to integrate spiritual beliefs into the rest of one’s life, as opposed to compartmentalizing “religious matters” apart from “mundane matters,” as is encouraged by modern culture. This daily integration will help provide successful navigation of and interaction with reality.

In the next post, we will talk about why people believe the things that they believe.

“…for this reason I have been born, and for this reason I have come into the world, to testify to the truth. Everyone who is of the truth hears my voice.” – Jesus, John 18:37cthe-truth-shall-make-you-free-1201069

“Follow truth, wherever it may lead.” – Thomas Jefferson (attrib.)

To establish the foundations of a reasonable trust in Christianity, we will start at the bottom of the study structure I outlined in my last post, and begin by talking about the nature and existence of truth. Although when in conversation with someone about the rationality of our beliefs it will not usually be required that you justify your understanding of truth, at times it will come up, and having thought through your foundational beliefs will serve you well in your defense. No Christian should fear fully investigating and seeking out truth, since, as Augustine puts it, “let every good and true Christian understand that wherever truth may be found, it belongs to his Master.” Establishing and understanding the existence and definition of truth is also needed for following arguments to build upon.

Correspondence Theory of Truth

So what is truth? According to the correspondence theory of truth, it is an accurate description of reality; a proposition is true if and only if it corresponds to the way things actually are. This is really quite intuitive. “Jonathan Wood owns a cherry red Ferrari” is true if and only if I actually own a cherry red Ferrari (I don’t, more’s the pity). This theory seeks to explain the conditions under which a proposition would be true, not how or if we can know the truth value of that proposition. “There is a hot pink golf ball on the planet Pluto” has a truth value of true or false, even if it is impossible for anyone to know that truth value.[1]

This illustrates the meaning and difference between two important philosophical terms pertaining to truth and knowledge which we will come back to frequently. Ontology relates to existence or being, while epistemology relates to how we attain and justify knowledge. These are important to understand as different, as it is not uncommon to mistakenly think that because one may not know the truth value of a particular sentence, it therefore has no truth value.

Attacks on Truth – Tolerance and Pluralism

The modern usage of “tolerance” is nearly useless; it is used now to mean that one should not indicate that another person is wrong about their beliefs.  If a moral or philosophical rule cannot meet its own standards, there is a problem. This new definition of tolerance self-destructs if applied to itself: questioning if this is itself a correct belief, or if a person who rejects this kind of tolerance should be tolerated.  No, tolerance only applies when there is a disagreement: disagreement is required.  Without a disagreement, there is nothing to tolerate.  Therefore, a proper view of tolerance should be applied to people, not ideas.  People are tolerated when they disagree with others, but no idea is so sacrosanct that it should be immune from evaluation and critique.

Concerning “religious pluralism,” if in using this concept one refers to the right to choose one’s religion without coercion, this is a good thing.  However, in today’s culture, the term has come to mean much the same as “tolerance” in that one ought not make exclusive truth claims about religious beliefs.  It fails in the same way that the redefinition of “tolerance” fails: it decries exclusivism in religious beliefs, but is itself an exclusive belief about religion, namely that only inclusive religious beliefs are acceptable.

Moreover, it should be clear that even if one is to accept this view of religious tolerance and pluralism, it cannot survive more than the most superficial and patronizing treatment of religious beliefs.  One does not have to look far to see that almost all the most important core beliefs of the world religions are in conflict with most other religions’ views.  As examples, regarding the concept of God, is God personal, impersonal, monotheistic, polytheistic, dualistic?  Is mankind part of creation but different in kind, an evolved ape, an illusion along with the rest of “reality”?  What about afterlife, does man cease to exist on death, go to heaven or hell, merge with the impersonal spirit force, or reincarnate?[2]  All of these views could be wrong, but they cannot all be right.  We must investigate the truth of which, if any, of the world’s religious views (including atheism) is correct.

Next time, we’ll investigate the question, What is knowledge?
