In Randy Alcorn's book "Happiness," a poignant observation by A.W. Tozer highlights the importance of maintaining a focus on heaven for followers of Christ. Tozer suggests that when believers lose their interest in eternal life, it results in a decline in their happiness. This lack of joy among Christians can diminish their ability to positively influence the world around them.

The idea emphasizes that genuine happiness in faith is closely tied to the hope of heaven. Without this perspective, Christians may struggle to manifest the joy and strength needed to confront the challenges of a sinful world. Thus, the message serves as a reminder that a heavenly focus is essential for spiritual vitality and impact.
