First, consider the universe’s origin. Science tells us the universe had a beginning. Logically, whatever begins to exist must have a cause outside of itself, something timeless, spaceless, and immensely powerful. The fine-tuning of the universe provides a second clue. The laws of physics, gravity, and chemistry are balanced on a razor's edge; if they were altered by even a fraction, life could not exist. This suggests an intentional designer rather than a random accident.
Third, we have objective morality. Across cultures, humans universally recognize certain things—like cruelty—as objectively wrong, not just personal opinions. This points to a higher moral lawgiver.
Finally, the historical case for Jesus. Historians widely agree that Jesus of Nazareth lived, was crucified, and that His early followers genuinely believed they saw Him alive afterward. The rapid rise of the early church, despite severe persecution, demands an explanation.
