C.S. Lewis's Spiritual Growth and Its Impact

C.S. Lewis's journey from atheism to Christianity and his subsequent spiritual growth are key to understanding the formation of his influential work 'Mere Christianity'. Much of this growth was shaped by his rigorous academic study of 16th-century literature, which allowed him to appreciate the complexities of Christian thought during the Reformation. Additionally, his relationship with Father Walter Adams, who served as a spiritual director for over a decade, led him to deep devotional practices and a transformative understanding of traditional Anglican theology. This mentorship not only impacted his character but significantly increased his literary output, allowing him to emerge as a notable Christian thinker of the 20th century.
