Jesus defined with utmost sharpness the nature of this mammon spirit. He unmasked the piety of the wealthy classes, exposing their worship of the spirit of death. This mammon spirit leads to war and causes impurity to become business. Murder and lying become daily life because of this will to possess. Jesus called Satan the murderer from the beginning, the leader of unclean spirits.
Murder is the nature of mammon.
Wars are not the only sign of the mammon spirit. We have become used to countless people being crushed to death because of our affluence, as if they were vermin to be squashed. Even the blind can see that the development of the mammon spirit means incessant murder of hundreds and thousands of people. Mammon and big business rule through the power of the lying spirit. It is impossible to wage war without a basic inner deception.
