Faith in Contemporary Life

The Cumulative Case for the Existence of God

Chris Cahill · 7 min read · First published 2024-10-27

What happens when several reasons for faith are considered together? The cumulative case approach brings arguments into conversation rather than relying on one alone. This reflection explores that approach without treating agreement as a requirement for being heard.

Below, we outline five particularly convincing arguments that together establish a strong foundation for belief in God. Regardless of whether one approaches this topic from a theistic perspective that affirms God's existence or from an atheistic viewpoint that rejects it, both stances necessitate a degree of faith. Nevertheless, as will be demonstrated, the evidence supporting the existence of God requires significantly less faith than the position of atheism.

1. The Cosmological Argument: A Necessary First Cause

The cosmological argument asserts that anything that comes into existence must have a cause. Since the universe came into being, it necessarily follows that it must have a cause—an uncaused, essential being that exists beyond the confines of time and space, which we refer to as God. This argument serves as a robust basis for the belief in a Creator, as it recognizes the logical impossibility of an infinite series of causes. As stated in Hebrews 3:4, “For every house is built by someone, but God is the builder of everything.” The universe itself indicates the presence of a builder, a Creator.

While the cosmological argument alone offers significant support for the concept of a necessary First Cause, its strength is amplified when considered alongside other arguments. The cause of the universe must not only exist but also possess specific attributes—such as power, knowledge, and purpose—that lead us directly to the conclusion of God's existence.

2. The Teleological Argument: Design in the Universe

The teleological argument highlights the evident fine-tuning and complex order present in the universe, indicating that such intricacy suggests the existence of an intelligent Designer. From the exact constants governing physics to the extraordinary complexity found in biological organisms, the universe seems meticulously arranged to support life. Psalm 19:1 states, "The heavens declare the glory of God; the skies proclaim the work of his hands." The universe is not merely a product of chance; it exhibits remarkable design, purpose, and beauty, all of which point towards a Designer.

This argument alone provides a compelling case for the existence of God, and when considered alongside the cosmological argument, it presents a robust depiction of a Creator who not only initiated the universe but also crafted it with intention and care.

3. The Moral Argument: Objective Morality Requires God

The moral argument posits that the existence of objective moral values and duties necessitates the existence of God. In the absence of God, morality becomes merely a matter of personal preference or societal conventions. Nevertheless, as indicated in Romans 2:14-15, “The law is written on their hearts, their consciences also bearing witness.” This suggests that all individuals possess an inherent understanding of right and wrong that transcends both time and culture, indicating the presence of a Lawgiver.

While the cosmological and teleological arguments provide evidence for the existence and design of the universe, the moral argument adds a personal aspect to the concept of God—He is not only a formidable Creator but also a moral entity who is concerned with human conduct. The presence of objective morality further bolsters the overall case for the existence of God.

4. The Argument from Consciousness: The Mystery of Mind

Human consciousness, characterized by the capacity for thought, reasoning, and self-awareness, continues to be one of the most profound enigmas in the realm of science. Naturalistic theories fall short in providing a satisfactory account of how mere matter and physical processes could lead to the emergence of subjective experiences. As stated in Genesis 2:7, “Then the Lord God formed a man from the dust of the ground and breathed into his nostrils the breath of life, and the man became a living being.” This passage suggests a divine being as the origin of both life and consciousness.

While each argument for the existence of God—be it cosmological, teleological, or moral—holds significant weight, the argument from consciousness introduces an additional dimension of understanding. Consciousness serves as a reflection of a conscious and intelligent Creator. When this argument is considered alongside the others, it further reinforces the notion of a personal God who engages with His creation.

5. The Argument from Religious Experience: Personal Encounters with the Divine

People in different cultures report experiences they understand as encounters with God. Believers may regard those accounts as significant; others offer different interpretations. Their meaning deserves examination without inventing a global count or treating prevalence as proof of their cause.

As stated in Acts 17:27, "God did this so that they would seek him and perhaps reach out for him and find him, though he is not far from any one of us."

While personal experiences may not sway a skeptic on their own, they contribute to a broader cumulative case that serves as a compelling testament to the reality of God. The fact that a diverse array of individuals throughout history report similar encounters with the divine implies that these experiences hold a degree of authenticity.

Faith and Worldviews: Belief in God vs. Atheism

Both the theist and the atheist operate from a foundational worldview that necessitates a degree of faith. For the theist, the belief in God is bolstered by a variety of rational arguments—such as cosmological, teleological, moral, and experiential—that collectively provide a framework for understanding the universe, morality, and human existence. Conversely, the atheist must place faith in a universe that is devoid of cause, purpose, and any basis for morality or consciousness. As Norman Geisler aptly noted, “I don’t have enough faith to be an atheist.” The preponderance of evidence suggests the existence of a Creator, indicating that it requires significantly less faith to accept the existence of God than to embrace a worldview of nihilism.

When atheism is scrutinized closely, it often leads to a profound belief in the notion that something can emerge from nothing, that life can originate from non-life, and that morality can exist without any foundational basis. In contrast, theism provides coherent and compelling answers to these profound questions.

Pascal’s wager: a further question

As we conclude this exploration, it is pertinent to reflect on Pascal’s Wager. Blaise Pascal, renowned philosopher and mathematician, posited that faith in God represents the most logical decision, even when considered from a strictly pragmatic standpoint. Should God exist, the believer stands to gain everything—eternal life, significance, and purpose. Conversely, if God does not exist, the believer forfeits nothing. In contrast, an atheist who is mistaken faces the potential loss of everything. As stated in Hebrews 11:6, “Without faith, it is impossible to please God, because anyone who comes to Him must believe that He exists and that He rewards those who earnestly seek Him.”

Pascal’s Wager does not aim to establish the existence of God; rather, it illustrates that faith in God is the most prudent and secure choice. When considered alongside the cumulative case, which robustly advocates for God’s existence through rationality and evidence, the wager becomes even more persuasive. Given the arguments presented, it is evident that belief in God is not only a rational stance but also the one that offers the most significant rewards.

Carrying this into life

The cumulative argument for the existence of God, which encompasses the cosmological, teleological, moral, consciousness, and religious experience arguments, presents a compelling and persuasive case for a Creator. While each argument possesses considerable merit on its own, their collective strength creates a formidable case for God's existence. The intricacies of the universe, its purposeful design, our innate moral sensibilities, our conscious experiences, and the personal testimonies of countless believers all suggest a God who is not only existent but also profoundly engaged with His creation.

Ultimately, both theism and atheism necessitate a degree of faith. Nevertheless, as demonstrated, it requires significantly more faith to reject the existence of God when confronted with the substantial evidence affirming His reality. The rational, coherent, and optimistic choice is to embrace belief in God, the Creator and Sustainer of all existence. As stated in James 4:8, “Draw near to God, and He will draw near to you.”

These arguments offer reasons to consider and questions to keep exploring. The invitation to faith can remain open without asking us to claim that every disagreement has been settled.

Let the reflection meet the next person you speak with. May wisdom help us listen, unity keep us open to one another, and grace become visible in the care we give.
