The Argument from Conscience Made Simple

The Argument from Conscience Made Simple

What is good for you, isn’t necessarily good for me. Did you hear that one before? I did! It is called ‘moral subjectivism’, and it is very popular in our western society. But things seems to change if you start to talk about one’s conscience. I have met many who do not, or who refuse, to believe in universally binding morals. They will absolutely rebel against the idea of someone or something that dictates an absolute moral standard. They quite often say that they only follow their own private conscience.

Define and Clarify

First we should define and clarify the word ‘conscience.’ The modern meaning tends to explain it as just a feeling that I did something wrong, or I am going to do something wrong. The traditional Biblical view is that conscience is the knowledge of right and wrong. So we just know what is right and wrong, it is not just a fuzzy feeling. For this argument we use the word conscience as a given knowledge and not just a feeling. Peter Kreefti said that

it is intuitive knowledge rather than rational or analytical knowledge, and it is first of all the knowledge that I must always do right and never wrong, the knowledge of my absolute obligation to goodness, all goodness: justice and charity and virtue and holiness; only in the second place is it the knowledge of which things are right and which things are wrong. This second-place knowledge is a knowledge of moral facts, while the first-place knowledge is a knowledge of my personal moral obligation, a knowledge of the moral law itself and its binding authority over my life. That knowledge forms the basis for the argument from conscience.

Reasons Given for our Conscience

It is striking that no one, not even the hardcore subjectivist, believes that it is right to, on purpose and deliberately, disobey one’s own conscience. Even though people have different ideas about what is good and what is bad, there remains one moral absolute for everyone: Never disobey your own conscience! Almost everybody will admit this idea. Christians will argue that it is our God-given compass, while the atheists will insist it has nothing to do with God whatsoever.

Let’s see what kind of explanations people use for this idea of conscience.

  1. It is given by nature. So it comes from something which is unguided and thus lesser than us.
    • But why should I absolutely obey something lesser than me? We all recognise that doing something purely out of instinct isn’t always the best way to go.
  2. It comes from our own individual thinking.
    • Am I the absolute standard to all things? What if I just don’t like the possible outcome? I just as easy shift my thinking and permit myself something I previously thought to be wrong.
  3. From other people within our society or from society as a whole.
    • Really? Am I going to allow others to dictate what is right and what is wrong? Who is to say that others are the authority on morals? If the whole society states that it is okay to experiment on twin babies? What if society think people should have only one child and if that child is a girl, that same society thinks it’s okay to dispatch off the baby. Do a thousand humans make a relative into an absolute?
  4. Or it comes from something higher than us. That what we call God. Actually, this is the only option left.
    • All the other options fail and this one is the only one most will feel as being absolute. Conscience is thus explainable only as the voice of God in the soul.

The Big No-Go

We live in a time when many think it is okay to disobey the church, the government, or any other figures of authority. However, the big no-go is still: Do not disobey your own conscience. This means that people usually believe in the absolute moral authority and binding duty of conscience. Off course, not many will say it in these words, but their action reveal it nonetheless.

Now we have to deal with this idea of ‘the voice of God in the soul’. As discussed, there seems to be not other option for the origin of our conscience. Some would say that this can be a variety of deities. Atheists like to point out that we could be talking about Zeus, Allah, or any other god we worshipped throughout the ages. Nope, the god-option can’t be right. So many will refer back to society or their own ideals, with all the inconsistencies taken for granted.

Why the Biblical God

Okay, why would this argument be best explained by the idea that it is the Biblical God, YHWH, who gave us our conscience? Among all the ancient gods, the God of the Jews was the first God who got identified as the source of moral obligation. The gods of the other people were maybe thought of in similar ways. Yes, they too required ritual worship, inspired fear, created the universe, or ruled over the events in human life, but none of them ever gave the Ten Commandments. Nope, it is only the God of the Bible who said, “Be ye holy for I the Lord your God am holy.”

Some would say that the Muslims worship the same god as we Christians do. Sure enough, there are rules to be found in Islam that look very similar to the commandments in the Bible. However, it was Jesus, the Son of God, who explained the commandments in a way we all understand as being superb! Love your neighbour as yourself; love your enemy, do to others what you want them to do to you, etc. Golden rules, which we mostly can find in our own conscience as well. Yes, Islam does teach similar rules, but they only apply to those who think the same. Quite different from that what Jesus taught us.

To Sum up the Argument

Let me conclude this argument with another citation from Peter Kreeftii:

To sum up the argument most simply and essentially, conscience has absolute, exceptionless, binding moral authority over us, demanding unqualified obedience. But only a perfectly good, righteous divine will has this authority and a right to absolute, exceptionless obedience. Therefore, conscience is the voice of the will of God.

Of course, we do not always hear that voice aright. Our consciences can err. That is why the first obligation we have, in conscience, is to form our conscience by seeking the truth, especially the truth about whether this God has revealed to us clear moral maps (Scripture and Church). If so, whenever our conscience seems to tell us to disobey those maps, it is not working properly, and we can know that by conscience itself if only we remember that conscience is more than just immediate feeling. If our immediate feelings were the voice of God, we would have to be polytheists or else God would have to be schizophrenic.


Do take a look in the description of this video! You’ll find ways to support me, or you could visit my website and read the transcript of this video. I always try to make the transcript available in Dutch and English. I would also like to invite you to my Odysee channel. Odysee is a platform which based on a new protocol called LBRY. Video that are uploaded through the LBRY protocol are censorship free, unlike others. It would be great if you start following me there. I am mostly active on that channel. You can also comment on my videos on BitChute or YouTube, but because of the aforementioned reason (speed internet) and because I am not very active on those two channels, you most likely won’t receive a reply there. If you want to start your own channel on Odysee you can use my invitation in the description. If you do, we will both receive some free LBC!

As always, thank you for watching, God bless you, and we see each other in the next video!

Apologetic Arguments Made Simple

What’s Next? See all videos below In previous videos, I have been talking that I wanted to do some videos on apologetic arguments. Until now, I have chosen different topics each time. Topics that some of you suggested and also topics suggested by my own family. The latest suggestion was that of the impact of […]

Ontological Argument Made Simple

Introduction In his 1078 work Proslogion, Anselm of Canterbury came with the idea which is known as ‘the ontological argument’. In this argument God’s existence is not just possible or probable or very likely, but is logically ensured. Anselm defined God as “that than which nothing greater can be thought”. Anselm said that this being […]

Cosmological Argument Made Simple

Do you know mister William Lane Craig? This is a hugely smart man, and listening to him sounds like you’re reading an official academic essay. I’ve written a lot of essays and I wish I could write them as fast as he formulates his sentences. Mister Craig is well known for his philosophical way of […]

Teleological Argument Made Simple

What do you think? Are we like orphans or are we citizens of our universe? Are we just an accident, a fluke, a product of mere chance? If we have to belief the secular world we are just a result of time, space, matter, chance and impersonal laws. No, the universe is just what it […]

Moral Argument Made Simple

A new video! On apologetics again. I promised in my last video to show you a bit of our road here in the countryside of Madagascar. So, stay tuned, because I will paste some of that footage at the end of this video. Anyway, let’s get started. I grew up in a time that knew […]

Religious Experience Argument Made Simple

We have discussed several arguments for God. Now we’ve come to the fifth argument and I think this one will tricker most resistance. The Religious Experience argument for the existence of God! A religious experience is when someone feels they have had a direct or personal experience of God. This argument basically says that if […]

Argument from Change Made Simple

The material world we know is a world of change. My oldest son is about 1.76 metre. But he was not always that height. When he was born, he was about 51 centimetres. Yes, he changed a lot during the last 15 years. General Sherman is the biggest tree in the world. According to estimates, […]

Argument from the Origin of the Idea of God Made simple

This argument is closely related to the ontological argument. It starts from the idea of God. However, unlike the ontological argument, it does not say that real being is part of the content of that idea. Nope, it tries to demonstrate that only God Himself could have make this idea to develop in our thoughts. […]

Argument from Miracles Made simple

This argument from miracles, and others, like the argument from religious experience and the argument from change, are not designed to prove the absolute existence of God they only claim a strong probability. Still, I include these kinds of arguments because they, together with all the other arguments, form a strong cumulative case. Other arguments […]

The Common Consent Argument Made Simple

In the last video, and the videos before I asked you whether you have any topics you would like me to discuss. So far, I have several. One of you want to talk about deism and why it is or isn’t a flawed idea. And Nortega came up with also a good topic. He said: […]

Pascal’s Wager

You Wanna Bet on it? My kids love to climb trees. Overall, I’m okay with that, but I normally give them one very important but simple rule: You are not allowed to fall out! And whatta you know… They tend to break that one simple rule every time. One day, one of them came running […]

Atheist’s Opinion – Again the Wager

Atheist Experience 30-03-2008i This wager thingy was still on my mind when I came across a YouTube channel called the ‘Atheist Experience.’ This channel is already running 13 years, so you could say that these guys are pretty experienced in them being atheistic and all. One of the faces of this channel is mister Matt […]
