In Joseph Heller's book "God Knows," the quote emphasizes the necessity of belief in God for stability and purpose in life. Heller suggests that without a spiritual anchor, individuals might seek out alternative paths, some of which could be misguided or extreme, such as witchcraft or other religions. This highlights the inherent human need for guidance and meaning, which is often found in a relationship with God.

The quote reflects a deeper philosophical viewpoint on how belief systems shape human behavior and decision-making. Heller argues that in the absence of a divine framework, one might wander into practices that lack a solid foundation, leading to potentially harmful choices. The broader implication is that faith serves as both a moral compass and a source of comfort in an uncertain world.
