“What is the definition of idolatry?”……The definition of idolatry, according to Webster, is "the worship of idols or excessive devotion to, or reverence for some person or thing." An idol is anything that replaces the one, true God. The most prevalent form of idolatry in Bible times was the worship of images that were thought to embody the various pagan deities.……From the beginning, God's covenant with Israel was based on exclusive worship of Him alone

(Exodus 20:3)"You shall have no other gods before me

(Deuteronomy 5:7)7 "You must not have any other god but me.. The Israelites were not even to mention the names of false gods

(Exodus 23:13)13 "Pay close attention to all my instructions. You must not call on the name of any other gods. Do not even speak their names. because to do so would acknowledge their existence and give credence to their power and influence over the people. Israel was forbidden to intermarry with other cultures who embraced false gods, because God knew this would lead to compromise. The book of Hosea uses the imagery of adultery to describe Israel's continual chasing after other gods, like an unfaithful wife chases after other men. The history of Israel is a sad chronicle of idol worship, punishment, restoration and forgiveness, followed by a return to idolatry. The books of 1 & 2 Samuel, 1 & 2 Kings, and 1 & 2 Chronicles reveal this destructive pattern. The Old Testament prophets endlessly prophesied dire consequences for Israel if they continued in their idolatry. Mostly, they were ignored until it was too late and God's wrath against idol-worship was poured out on the nation. But ours is a merciful God, and He never failed to forgive and restore them when they repented and sought His forgiveness.……In reality, idols are impotent blocks of stone or wood, and their power exists only in the minds of the worshipers. The idol of the god Dagon was twice knocked to the floor by God to show the Philistines just who was God and who wasn't (1 Samuel 5:1-5) After the Philistines captured the Ark of God, they took it from the battleground at Ebenezer to the town of Ashdod. 2 They carried the Ark of God into the temple of Dagon and placed it beside an idol of Dagon. 3 But when the citizens of Ashdod went to see it the next morning, Dagon had fallen with his face to the ground in front of the Ark of the Lord! So they took Dagon and put him in his place again. 4 But the next morning the same thing happened-Dagon had fallen face down before the Ark of the Lord again. This time his head and hands had broken off and were lying in the doorway. Only the trunk of his body was left intact. 5 That is why to this day neither the priests of Dagon nor anyone who enters the temple of Dagon in Ashdod will step on its threshold..

The "contest" between God and His prophet Elijah and the 450 prophets of Baal on Mount Carmel is a dramatic example of the power of the true God and the impotence of false gods.

(1 Kings 18:19-40)19 Now summon all Israel to join me at Mount Carmel, along with the 450 prophets of Baal and the 400 prophets of Asherah who are supported by Jezebel.* "

20 So Ahab summoned all the people of Israel and the prophets to Mount Carmel. 21 Then Elijah stood in front of them and said, "How much longer will you waver, hobbling between two opinions? If the Lord is God, follow him! But if Baal is God, then follow him!" But the people were completely silent.

22 Then Elijah said to them, "I am the only prophet of the Lord who is left, but Baal has 450 prophets. 23 Now bring two bulls. The prophets of Baal may choose whichever one they wish and cut it into pieces and lay it on the wood of their altar, but without setting fire to it. I will prepare the other bull and lay it on the wood on the altar, but not set fire to it. 24 Then call on the name of your god, and I will call on the name of the Lord. The god who answers by setting fire to the wood is the true God!" And all the people agreed.

25 Then Elijah said to the prophets of Baal, "You go first, for there are many of you. Choose one of the bulls, and prepare it and call on the name of your god. But do not set fire to the wood."

26 So they prepared one of the bulls and placed it on the altar. Then they called on the name of Baal from morning until noontime, shouting, "O Baal, answer us!" But there was no reply of any kind. Then they danced, hobbling around the altar they had made.

27 About noontime Elijah began mocking them. "You'll have to shout louder," he scoffed, "for surely he is a god! Perhaps he is daydreaming, or is relieving himself.* Or maybe he is away on a trip, or is asleep and needs to be wakened!"

28 So they shouted louder, and following their normal custom, they cut themselves with knives and swords until the blood gushed out. 29 They raved all afternoon until the time of the evening sacrifice, but still there was no sound, no reply, no response.

30 Then Elijah called to the people, "Come over here!" They all crowded around him as he repaired the altar of the Lord that had been torn down. 31 He took twelve stones, one to represent each of the tribes of Israel,* 32 and he used the stones to rebuild the altar in the name of the Lord. Then he dug a trench around the altar large enough to hold about three gallons.* 33 He piled wood on the altar, cut the bull into pieces, and laid the pieces on the wood.

Then he said, "Fill four large jars with water, and pour the water over the offering and the wood."

34 After they had done this, he said, "Do the same thing again!" And when they were finished, he said, "Now do it a third time!" So they did as he said, 35 and the water ran around the altar and even filled the trench.

36 At the usual time for offering the evening sacrifice, Elijah the prophet walked up to the altar and prayed, "O Lord, God of Abraham, Isaac, and Jacob,* prove today that you are God in Israel and that I am your servant. Prove that I have done all this at your command. 37 O Lord, answer me! Answer me so these people will know that you, O Lord, are God and that you have brought them back to yourself."

38 Immediately the fire of the Lord flashed down from heaven and burned up the young bull, the wood, the stones, and the dust. It even licked up all the water in the trench! 39 And when all the people saw it, they fell face down on the ground and cried out, "The Lord-he is God! Yes, the Lord is God!"

40 Then Elijah commanded, "Seize all the prophets of Baal. Don't let a single one escape!" So the people seized them all, and Elijah took them down to the KishonValley and killed them there.

The testimony of Scripture is that God alone is worthy of worship. Idol worship robs God of the glory that is rightfully His, and that is something He will not tolerate

(Isaiah 42:8)8 "I am the Lord; that is my name! I will not give my glory to anyone else,nor share my praise with carved idols.

…Even today there are religions that bow before statues and icons, a practice forbidden by God's Word. The significance God places upon it is reflected in the fact that the first of the Ten Commandments refers to idolatry: "You shall have no other gods before me. You shall not make for yourself an idol in the form of anything in heaven above or on the earth beneath or in the waters below. You shall not bow down to them or worship them; for I, the LORD your God, am a jealous God, punishing the children for the sin of the fathers to the third and fourth generation of those who hate me"

(Exodus 20:3-5) 3 "You must not have any other god but me.4 "You must not make for yourself an idol of any kind or an image of anything in the heavens or on the earth or in the sea. 5 You must not bow down to them or worship them, for I, the Lord your God, am a jealous God who will not tolerate your affection for any other gods. I lay the sins of the parents upon their children; the entire family is affected-even children in the third and fourth generations of those who reject me.

…Idolatry extends beyond the worship of idols and images and false gods. Our modern idols are many and varied. Even for those who do not bow physically before a statue, idolatry is a matter of the heart-pride, self-centeredness, greed, gluttony, a love for possessions and ultimately rebellion against God. Is it any wonder that God hates it?
