Podcast Summary: Ultimately with R.C. Sproul

Episode: Agnosticism Is Not an Option
Date: May 1, 2026
Host: Ligonier Ministries
Speaker: R.C. Sproul

Overview

In this episode, R.C. Sproul tackles the subject of agnosticism and argues that professed ignorance of God's existence is not a legitimate excuse, especially in the context of ultimate accountability before God. Drawing from scriptural insights—particularly the Apostle Paul's warning in Romans—Sproul addresses common claims made by agnostics, explores the nature of knowledge and ignorance, and makes a compelling case that everyone indeed knows God exists. The episode encourages listeners to focus on essential truths and understand the gravity behind claims of ignorance regarding God.

Key Discussion Points and Insights

1. The Excuse of the Agnostic (00:00–01:35)

R.C. Sproul opens by critiquing the common rationale of self-proclaimed agnostics:
- Quote [00:00]:
  "The excuse of every self-proclaimed agnostic: I didn't know the gun was loaded. If I just would have known."
- Sproul likens agnosticism to pleading ignorance, especially at final judgment.

2. The Meaning of Agnosticism and Its Implications (01:00–02:00)

Sproul explains definitions:
- Theism is affirming the existence of God/gods.
- Everything outside theism—including agnosticism—falls under the label of atheism.
He provocatively calls agnosticism "the worst kind of atheist" because it refuses to affirm God’s existence and lays blame on God for supposed lack of evidence.
- Quote [01:06]:
  "The agnostic is outside the category of the theist because he will not affirm the existence of God and then blames God for it."
He connects the word "agnostic" (Greek: agnosis, “without knowledge”) with the Latin "ignoramus," emphasizing the claim of ignorance.

3. The Futility and Rejection of Ignorance as Excuse (01:30–02:45)

Sproul describes the typical agnostic plea:
- If only God had revealed Himself more clearly, the agnostic would have believed.
Challenges this plea by emphasizing natural revelation:
- Quote [01:41]: "Despite every moment of that person's existence, the heaven is declaring the glory of God and God is manifesting himself plainly and clearly to his eternal power and deity before his very eyes and in the midst of his soul..."
All humans, Sproul argues, know God exists through the revelation in creation and conscience.
- He references Paul’s statements in the Book of Romans, highlighting that everyone is "without excuse."

4. The Universal Knowledge of God (02:20–02:49)

Sin, according to Sproul, isn’t ignorance of God but refusal to acknowledge Him despite knowing the truth.
- Quote [02:20]: "The sin of man is not that we don't know him, it's that we refuse to acknowledge him even though we do know Him."
He stresses that ignorance will not stand as a legitimate defense:
- Quote [02:45]: "Paul warns that ignorance is not going to be an excuse on the Day of Judgment because it's not true. We are not ignorant. We are not without knowledge. We are not. Ah, Ganosis."

The excuse of every self proclaimed agnostic. I didn't know the gun was loaded. If I just would have known. Paul warns that ignorance is not going to be an excuse on the Day of Judgment. I was talking to somebody this week and they were telling me he said so and so. My friend is not an atheist, he's an agnostic. I said, an agnostic is the worst kind of atheist. And he said, what do you mean? I said, well, theism means that you affirm the existence of God or gods. Atheism covers everything outside the category of theism. And the agnostic is outside the category of the theist because he will not affirm the existence of God and then blames God for it. Says, the reason I can't affirm the existence of God is because I am agonosco. I am without knowledge. The Latin translation of agnosis or agnostic is ignoramus. I am ignorant. Then the plea of the agnostic is oh God, if you just would have made yourself known to me, if you just would have shown me a miracle, if you just would have given me sufficient data to make a rational judgment, I would have been your most faithful supporter that despite every moment of that person's existence, the heaven is declaring the glory of God and God is manifesting himself plainly and clearly to his eternal power and deity before his very eyes and in the midst of his soul, so that every human being that walks upon this earth and knows and knows with certainty that God exists. The sin of man is not that we don't know him, it's that we refuse to acknowledge him even though we do know Him. And when Paul says in Romans that they will be without excuse, what excuse do you think they'll be resting upon? The excuse of every self proclaimed agnostic. I didn't know the gun was loaded. If I just would have known that you were there, I would have repented. I would have embraced the Savior. But I just missed it. Didn't get it. Please forgive me for my ignorance. Paul warns that ignorance is not going to be an excuse on the Day of Judgment because it's not true. We are not ignorant. We are not without knowledge. We are not. Ah, Ganosis.
