In I Don't Have Enough Faith to Be an Atheist, Norman L. Geisler and Frank Turek argue that Christianity is the most reasonable worldview. They say that atheism requires more faith than Christianity because it must explain the universe's existence, the fine-tuning of the universe for life, the existence of objective moral values, and the historical evidence for Jesus' resurrection without recourse to God. They argue that the evidence from cosmology, biology, morality, and history points to the existence of a personal, theistic God and that the New Testament documents provide reliable testimony to the life, death, and resurrection of Jesus Christ.

Geisler (1932-2019) was...

I Don't Have Enough Faith to Be an Atheist Summary Foundational Arguments: Truth, Divinity, and Knowledge Potential

Geisler and Turek begin by asserting that truth is definite, limited, and singular. It eliminates opposing concepts.

(Shortform note: Philosopher Michael P. Lynch disagrees with the authors’ assertion that truth is definite, limited, and singular. In Truth as One and Many, Lynch argues that truth is a pluralistic concept that can be realized in different ways across different domains.)

They also argue that theism aligns with the Biblical God. Theism is the belief in a single, infinite, eternal God who is the universe's creator and to whom all creatures are ultimately accountable. The authors claim that theism can be identified through logic, scientific methods, and philosophical thought, independent of scripture. This is known as natural or general revelation, while revelation from sacred texts is called special revelation. Through natural revelation, they argue, we know theism is accurate, which means all nontheistic worldviews must be incorrect. They go on to say that only one of the three main theistic world faiths—Judaism, Christianity, or Islam—could be accurate. Every other principal world religion must be incorrect since they aren't...

I Don't Have Enough Faith to Be an Atheist Summary Evidence for Christian Beliefs: Miracles, Scripture, and Jesus' Words

Geisler and Turek argue that scripture provides evidence for Jesus’ miracles and resurrection. They claim that the New Testament authors had every reason to reject its events, rather than fabricate or embellish them. The majority of these authors were deeply committed Jews who believed Judaism was the sole true faith. Something significant must have occurred to disrupt their beliefs and prompt them toward a new paradigm that only guaranteed earthly suffering.

(Shortform note: Historian Candida Moss challenges the idea that the New Testament authors had every reason to reject its events and only earthly suffering to gain. In The Myth of Persecution, Moss argues that the early Christian community’s persecution was exaggerated and that the stories of martyrdom were often fabricated or embellished. She explains that later Christian communities expanded and stylized these stories to promote their theological agendas, rather than to provide neutral testimony.)

The New Testament texts were crafted by people who either witnessed the events firsthand or were alive at the same time, within two generations of the occurrences, and the story is...
