I recently read a book by Greg Boyd titled "The benefit of the Doubt." The book is about faith, doubt, and certainty. I'm concerned that I may not represent his views accurately, but I will try my best. But this is not a book review.
The past few years, I've been hearing this idea that faith and belief do not mean the same thing. One of then includes doubt. I don't remember which one, but Boyd says that faith includes doubt, so maybe it is faith. I must admit that I found this problematic from the first time I heard it. For it seems to me that the words themselves do not support such a distinction. The Greek word for faith is the same for belief, being “pistis”; and of course “believe” is a verb, which is “pisteuo.” I would think the difference between the words is how one best fits in a sentence; that is, the word “faith” may work better than “belief,” and then it depends on whether you use a noun or a verb. However, one can choose to use “faith” to include doubt, and to use “belief” to not include doubt but the words themselves do not give indication that one includes doubt and the other does not. If faith and doubt can be used interchangeably in a context, it would seem they mean the same thing. If one includes doubt, then they both do. Wouldn't they?
Boyd believes that faith includes doubt, and that faith has the idea of “trust”--a trust that allows you to act accordingly in-spite of your doubt. At least that is how I understood him. He sees doubt as being honest, and certainty as being proud and unwilling to change ones view. He even calls certainty idolatry or the pursuit of certainty as idolatry. That's how I understood him.
I'm not sure about the idolatry claim, but I know that certainty can come across arrogant to others. I see certainty as a kind of confidence that can manifest itself as arrogant, depending on how it appears. David had a certain kind of confidence that came across as arrogant to his brother, when he came to where the battle was: “28 Now Eliab his oldest brother heard when he spoke to the men; and Eliab's anger was aroused against David, and he said, "Why did you come down here? And with whom have you left those few sheep in the wilderness? I know your pride and the insolence of your heart, for you have come down to see the battle." 1 Samuel 17:28 Was David's confidence in God idolatry? I see his confidence producing a kind of bravery because of his particular belief in God. Am I wrong about this?
Certainty as a kind of confidence depends on the object and context. There are things I believe that we can be certain about and things that are not guaranteed. I can be certain that God is able to heal me, but I am not certain that he will. I see these as 2 different things, not one thing. I am certain that God cannot lie, but I don't know what He might do in a certain situation. It seems to me that certainty depends on the object of faith and what is actually being offered. Sometimes we are mistaken about what God says or promises in Scripture. If I have faith the size of a mustard seed, can I really tell a mountain to go jump in the water? What is being communicated in those words? Can I be certain that I can receive anything I believe God for? I don't believe so. Yes, I actually doubt it. But I do believe the object of faith is an issue, and certainty depends on the object. I can be certain that Jesus is coming again, but I am uncertain concerning the timing—such as “pretrib.” Though I know that some can be certain about the timing. I might say that I see one view more likely than the other, so maybe that indicates there is some doubt in my own belief. Fine.
Boyd saw a problem, a kind of hypocrisy, in those who considered it pride if one was not willing to doubt their view while they were not willing to doubt their own view. I would suggest that we shouldn't expect someone to doubt their view, but to be willing to consider a different viewpoint. It's not wrong to be certain of something, and yet be willing to consider a different viewpoint. It's probably true that one won't have a change of mind until they begin to doubt what they believe, but it doesn't necessarily have to begin with doubt. I have had a change of mind on some things that didn't necessarily begin with doubt, but a curiosity as to why someone had a different view than I did—so I looked into it.
Boyd sees doubt as a good thing, because then may be willing to consider a different viewpoint. But as I said in the previous paragraph, one does not have to doubt to consider a different viewpoint. If one does have doubt, it is good to consider why you doubt. Because it may mean you lack assurance. John the Baptist begin to be uncertain if Jesus was the one, the specific one to come, and so he sent his disciple to Jesus to ask him if he was the one—which reveals that he still believed he was sent from God, because, how could John even trust him to speak the truth? Jesus answered his inquiry by working some miracles to attest to who he was.
I don't know what Boyd would say about John the Baptist's doubt, but Boyd does make some interesting points about the difference between doubt and wavering. And I think there may be some merit in the distinction between the two, but I tend to think it involves the object of faith. Boyd would say to have doubt is not bad, but to waver would be. He says that the word translated “doubt,” as in James chapter one should be understood as “waver.” I find that interesting (and maybe possible). If one lacks wisdom, one should ask in faith without wavering (as opposed to doubt); in other words, you should precede to trust God for the wisdom and not waver. But I confess I have a little trouble distinguishing between wavering and doubt. So, I trust God and not waver but I can still have doubt? Ok. I'm not sure about this. I guess he means that one should live their life consistent with expecting that God will give wisdom (trust without wavering), but what is the doubt about? I suppose Boyd is thinking that deep down inside me there may be an uncertainty that I will receive the wisdom that God promises., but I should press on trusting that the wisdom will come, regardless of the doubt I might feel—this would be trust God without wavering.
One other thing I want to bring up--and I'm doing this from memory, so I hope I represent Boyd correctly on this—is his discussion of Hebrews 1:1: “Now faith is the substance of things hoped for ...” Hebrews 11:1 I am only looking at the first part of this verse, which seems to give a definition of faith. I spent quite a bit of time thinking about this entire verse early this year (2025), trying to understand the Greek words translated “substance” and “evidence” (but not looking at that word here) in the KJV. I was teaching on the topic of “faith” as used in Scripture at Church in a small group, and I was finding myself uncertain how to best translate Hebrews 1:1. What does the KJV mean by “substance?” The Greek word is “hypostasis.” “Faith” is the “substance” of things hoped for—what does that mean? Other translations have words like “assurance” or “confidence.” I understand those words better, but they are quite different in meaning, and easier to make sense of. Faith is the assurance and confidence of things hoped for. I wanted to conclude that the Greek word had a broad range of meaning or usage, and “assurance” fits best. But the Greek word appears elsewhere in Hebrews and seems to mean “substance”: “[Jesus] who being the brightness of His glory and the express image of His person [hypostasis]” Hebrews 1:3 Jesus is the express image of God's hypostasis. The KJV translates “person,” but it could be “substance.” What does this mean?
My Greek lexicon says the best meaning is “realization”: “faith is the realization of things hope for.” I don't know, does that help? Boyd sticks with the word ”substance” and says that faith is something like the substantializing of things hoped for. I take that to mean that by one's actions, that reveal a trust in God, one substantiates the thing hoped for. Something like that. Does that make sense? There is a connection between what one does and believes, and there is a sense in which actions fulfills faith, and that is one way of understanding James statement about faith being made complete through works: “Do you see that faith was working together with his works, and by works faith was made perfect?” James 2:22 The word “perfect” can be understood as “complete.” So I think that Boyd was saying something about how faith substantializes the things hoped for by how it is made compete in actions of trust in God. I do believe Hebrews 11 is showing what living by faith looks like with the many examples from the Old Testament. So, I don't know if this discussion was of any help. But I will leave it at that.
I do think that calling “certainty” idolatry is rather extreme, but I do understand how some people may come across as arrogant in their faith and could maybe be dishonest or hypocritical in some way. But I think that certainty depends on the object and context and understanding of what is believed. I don't see a problem with being certain about some things, especially the character of God—because if God does lie, everything changes, and nothing is certain.
