C.S. Lewis, in his book "The Problem of Pain," emphasizes that those who are pure in heart possess a sincere desire to know and see God. This purity of intention is a key aspect of faith, suggesting that real longing for divine connection is rooted in a clean and sincere heart. Such individuals are genuinely motivated to seek a deeper understanding and relationship with the divine.

Lewis reassures that it is safe to promise these pure-hearted souls that they will encounter God. This assurance underlines the importance of inner purity as a prerequisite for spiritual fulfillment and reinforces the notion that true desire to connect with the divine is a vital step towards experiencing it fully.
