Our Lord says to be on your guard against “every form of greed” in Luke 12:15. The way I see it, greed is the interlocking component that cements so many other sins together. If the heart is self-focused, looking for status in worldly stuff, it will be materialistic. More is always equivalent with success – admiration from others, joy in possessions, fulfillment in things. Thus a materialistic heart will be produced. The heart will always want more. Greed is then the result. The comparison game will begin. The result will be more sins like boasting (because we have more) or coveting, jealousy and envy (because we have less) – leading to a general attitude sins like discontentment and ingratitude and selfishness. All this concludes (and comes full circle) with the worship of a false god, the chief sin of idolatry (notice the connection in Eph. 5:5 and Col. 3:5).
