Without a divine lawgiver, moral values lack an absolute, unchanging foundation. In a purely secular or naturalistic world, moral principles become subjective, changing with time, culture, or personal opinion. Religion anchors morality in the eternal nature or commands of a divine being, providing a universal standard that transcends individual or societal preferences.

Religious belief offers powerful incentives for moral conduct—such as divine reward (e.g., heaven) and punishment (e.g., hell). For many, this system encourages accountability, especially in situations where secular consequences are absent.
