In C.S. Lewis's "A Grief Observed," the author reflects on the nature of seeking divine assistance, particularly the idea encapsulated in the quote "Knock and it shall be opened." He questions whether this "knocking" implies a forceful or aggressive approach to prayer, suggesting it might not be about fervently demanding from God, but about approaching with humility and sincerity.

Lewis's exploration emphasizes a deeper understanding of faith and spiritual inquiry. Rather than treating prayer as a method to forcefully extract answers, he illustrates the necessity of patience and the quiet expectation that comes from genuine communion with the divine.
