An Idol is anything that takes the place of God

A true believer in the Almighty will not worship false gods be it idols, treasures or anything else.

Idols need not be only statues, but anything that people try to set up above the Lord God. In this evil and adulterous generation, therefore one must have control over one’s appetites, for anything and everything, lest you become the laughing-stock of your enemies. Your true enemies are first and foremost all those in enmity with the Lord God. Rest of your enemies are just personal and temporal enemies.

Do not be idolaters as some of them were; as it is written, “The people sat down to eat and drink and rose up to play.” (1 Corinthians 10:7)

Therefore, my beloved, shun the worship of idols. (1 Corinthians 10:14)

Every evil earthly nature that causes sinfulness towards God must be eliminated from your life if you claim to truly worship the Lord God. Or else its just a waste of time. No matter how natural the world justifies sin to be, get ride of all your base desires, before they all give you the fruit of your unjust labours.

Put to death therefore what is earthly in you: fornication, impurity, passion, evil desire, and covetousness, which is idolatry. (Colossians 3:5)

Now the works of the flesh are plain: fornication, impurity, licentiousness, idolatry, sorcery, enmity, strife, jealousy, anger, selfishness, dissension, party spirit, envy, drunkenness, carousing, and the like. I warn you, as I warned you before, that those who do such things shall not inherit the kingdom of God. (Galatians 5:19-21)
