The idols of the heathen are the work of man. They have no power or true spiritual significance:
The idols of the heathen are silver and gold, the work of men's hands.
They have mouths, but they speak not; eyes have they, but they see not;
They have ears, but they hear not; neither is there any breath in their
mouths.
They that make them are like unto them: so is every one that trusteth in
them. (Psalms 135:15-18) (See also Psalms 115:4-8).
A Christian cannot worship idols:
And what agreement hath the temple of God with idols?
(II Corinthians 6:16)
You are not to even keep company with idolaters:
But now I have written unto you not to keep company, if any man that is
called a brother be a fornicator, or covetous, or an idolater, or a railer, or a
drunkard, or an extortioner; with such an one go not to eat.
(I Corinthians 5:11)
You are warned to keep yourself from idols:
Little children, keep yourselves from idols. (I John 5:21)
Idolaters will not be part of the Kingdom of God:
Know ye not that the unrighteous shall not inherit the kingdom of God? Be
not deceived...neither idolaters...shall inherit the kingdom of God.
(I Corinthians 6:9-10)
The Bible reveals the destination of idolaters:
But the fearful, and unbelieving, and the abominable and murderers, and
whoremongers, and sorcerers, and idolaters, and all liars, shall have their
part in the lake which burneth with fire and brimstone; which is the second
death. (Revelation 21:8)
For without are dogs, and sorcerers, and whoremongers, and murderers, and
idolaters, and whosoever loveth and maketh a lie. (Revelation 22:15)
