Five Proofs of God

Philosophical Arguments for His Existence Through Reason and Evidence

1

The Cosmological Argument

"Everything that begins to exist has a cause. The universe began to exist. Therefore, the universe has a cause."

Core Question: Why is there something rather than nothing?

2

The Teleological Argument

"The universe displays fine-tuning and design. Fine-tuning is best explained by an intelligent designer."

Core Question: Over 100 universal constants precisely calibrated for life.

3

The Ontological Argument

"It is possible that a maximally great being exists. If possible, it exists in some possible world. A maximally great being exists in every possible world — including ours."

Core Question: Can the concept of God prove His existence?

4

The Moral Argument

"If God does not exist, objective moral values do not exist. Objective moral values do exist. Therefore, God exists."

Core Question: Without God, morality is just opinion.

5

The Contingency Argument

"Everything that exists has an explanation. The universe exists. Its explanation must be a necessary being — God."

Core Question: The universe doesn't have to exist. Something made it so.

Each argument includes detailed deep dives, common objections and scholarly responses, and connections to the broader cumulative case for God's existence. The full PDF walks through all five with philosophical rigor accessible to any reader.

Where I'm honest with you

Some of the answers in this resource are strong — well-attested, widely accepted, and historically grounded. Others are an honest step of faith — positions I hold because of Scripture and personal experience, not because I can prove them in a lab. I've tried to be clear about which is which. Where I'm less certain, I say so.
