The question of God's existence has always been a central issue in philosophy and theology, even amidst the development of science and contemporary secularism. This article examines the relevance of cosmological and teleological arguments as rational foundations for belief in God's existence. This paper employs qualitative research using a literature review approach and descriptive analysis. The cosmological argument emphasizes that the existence of the universe requires a first cause beyond itself, while the teleological argument highlights the order and purpose inherent in the cosmos that cannot be explained by mere chance. Both have classical roots in the thought of Thomas Aquinas and William Paley, but have found actualization in modern discourse through figures such as William Lane Craig and Richard Swinburne. While criticism from skeptical thinkers, such as David Hume and Richard Dawkins, has questioned their validity, both arguments nevertheless offer important contributions to the dialogue between faith, philosophy, and science. This study argues that, despite not providing absolute proof, the cosmological and teleological arguments provide a strong intellectual foundation for belief in God's existence and demonstrates their relevance for reflection on Christian faith in the contemporary era.
