The key to all the greatest insights of religion, psychology, sociology, anthropology, and political science
is the Bible,
or would be, if it was taken seriously - mostly by the very people who claim to honor it.

Humanity remains ignorant and anemic in the face of conflict, violence, crime and war
because it generally ignores the essential biblical insights about all these things,

namely:

-Once we reject the doctrine of the devil - that is, a deceiving, condemning spirit that works in all of us - we project our inherent belief in and need for a devil on to some person or group.

-Once we reject the doctrine of sin - that is, an inherent shared human problem of ignorance, illness, or corruption - we project our inherent belief in and need for knowing the problem on to the basic perceived faults of some type of person.

-Once we reject the doctrine of a Savior - that is, a person or human type that can "deliver us from evil" (however we conceive of evil) - we project our inherent belief in and need for a Savior on to some politician, teacher, film star, pop singer, athlete or potential mate.

-Once we reject the doctrine of biblical salvation - that is, a freeing from our bondage and empowering to do remarkable good (however we conceive of bondage and good) - we project our inherent belief in and need for such freeing and empowering on to money, the next election, beauty, our favorite music, alcohol, science, education, success, physical strength, some significant relationship, or some special expertise.

-Once we reject the doctrine of the Heaven - that is, a place of ultimate mercy, justice, beauty, safety and reward - we project our inherent belief in and need for a heaven on to some imaginary and illusory earthly utopia, political social ideal, or ultimate ideal or dream come true.

-Once we reject the doctrine of an authoritative scripture - that is, a source of profound and helpful ideas that has a proven trustworthiness - we project our inherent belief in and need for an authoritative source on to some other person's ideas or set of writings, songs or films.

and etc. (the examples are probably endless).
