In Randy Alcorn's book "Heaven," he reflects on the complex relationship humans have with the concept of heaven. He notes that at times, it may seem as though people are indifferent to the idea of an afterlife, yet he feels that deep down, there is an inherent yearning for something greater. This desire for heaven speaks to a fundamental aspect of human nature, where an intrinsic longing for fulfillment and connection to the divine exists.
Alcorn uses C. S. Lewis's sentiment to illustrate that while we may occasionally question our longing for heaven, it often underpins our existence. He suggests that our true aspirations and desires are aligned with an ultimate hope for a perfect future, which reflects humanity's pursuit of meaning and transcendence. This perspective encourages readers to explore their own hearts and the deeper desires that point toward a yearning for a heavenly existence.
