But without God, everything is meaningless, emptiness, vanity, idolatry. He lumps greed together with sexual immorality, impurity, passion and evil desire. The desire to accumulate riches and wealth falls under the same condemnation as sexual sin, lust, and wicked desires. All sin at its heart is idolatry, the worship of the self over and against God. Making yourself a god in place of God.
Idolatry is always a matter of the heart.
Where God is not at the center, the heart becomes a factory for idols, cranking out one false god after another. The thing about false gods is that they always work their worshipers to death. They consume their communicants. Greed is idolatry, the worship of false gods. It is a deadness in the heart toward God.
