Mammon is a biblical word that refers to worldly (vs. spiritual) "wealth". It derives from the Aramaic word for wealth. In the Bible, "Memon" is referred to as a master competing with God for the soul in an almost Satanic way.
|“||No man can serve two masters: for either he will hate the one, and love the other; or else he will hold to the one, and despise the other. Ye cannot serve God and mammon. - Matthew 6:24||”|
Some see "mammon" as a human-created personification of greed for wealth or power. However, others say that this was an idol, which would be worshiped in the hopes that he would give riches to his followers. Some even say that Mammon is an active, demonic spirit which is always near money.
Although interpretations vary, the implication is that the pursuit of riches and power, or greed, is in some way or form, evil. Whether it is a human-made concept, a false god, or an evil spirit, it is clearly described in scripture as something to avoid.
