C.S. Lewis, in "The Problem of Pain," presents a compelling view of heaven and hell in relation to humanity. He suggests that entering heaven signifies an enhancement of one's humanity, a fulfillment of potential that surpasses earthly existence. It's a journey toward achieving the best version of oneself, aligning with the ultimate purpose of existence. This perspective emphasizes growth and transformation in the afterlife, where one becomes more truly human than ever before.

Conversely, Lewis describes hell as a state of estrangement from humanity. Being banished from humanity implies a loss of essence and connection, leading to suffering and despair. Rather than flourishing, a soul in hell experiences a stark separation from the very qualities that define being human. This duality highlights the significance of our actions and choices in life, affecting our spiritual outcome in the afterlife.
