But just how serious is God about paganism?

When He rescued the twelve tribes of Israel from brutal slavery and led them out of Egypt, He commanded them, “After the doings of the land of Egypt, wherein you dwelt, shall you not do: and after the doings of the land of Canaan, where I bring you, shall you not do: neither shall you walk in their ordinances” (Lev. 18:3). God demanded the Israelites not to defile themselves with the pagan practices and customs of surrounding nations (vs. 24-29). “Therefore shall you keep Mine ordinance, that you commit not any one of these abominable customs, which were committed before you, and that you defile not yourselves therein: I am the LORD your God” (vs. 30).

God cursed Egypt—a nation of nature-worshiper—with ten plagues and freed Israel from slavery. He rescued Israel from Pharaoh’s army by parting the Red Sea and leading His people to safety. He fed the Israelites manna—special bread made by God—from heaven. He protected them from battle-tested Gentile armies, delivered them into the Promised Land and drove out their enemies.

How did Israel treat God in return? “Our fathers understood not Your wonders in Egypt; they remembered not the multitude of Your mercies; but provoked Him at the sea, even at the Red Sea…They soon forgot His works; they waited not for His counsel: But lusted exceedingly in the wilderness, and tempted God in the desert…They made a calf in Horeb, and worshiped the molten image. Thus they changed their glory into the similitude of an ox that eats grass. They forgot God their Savior, which had done great things in Egypt; wondrous works in the land of Ham, and terrible things by the Red Sea…they despised the pleasant land, they believed not His word: But murmured in their tents, and hearkened not unto the voice of the LORD …They joined themselves also unto Baal-peor, and ate the sacrifices of the dead. Thus they provoked Him to anger with their intentions” (Psa. 106:7, 13-14, 19-22, 24-25, 28-29).

God explicitly commanded Israel to cast out and utterly destroy all nations that occupied the Promised Land (Canaan). Above all, His people were not to make political alliances with them or marry into their families (Deut. 7:1-3, 5, 16). “For they will turn away your sons from following Me, that they may serve other gods” (vs. 4).

But the Israelites thought they knew better than God. They decided to do things their own way. “They did not destroy the nations, concerning whom the LORD commanded them: But were mingled among the heathen, and learned their works. And they served their idols: which were a snare unto them. Yes, they sacrificed their sons and their daughters unto devils [demons], and shed innocent blood, even the blood of their sons and of their daughters, whom they sacrificed unto the idols of Canaan: and the land was polluted with blood. Thus were they defiled with their own works, and went a whoring with their own inventions” (Psa. 106:34-39).

To wake them up and get them back on track as the model nation He had originally intended, God gave Israel over to their enemies. Israel repented and cried out to God. God rescued them. With their bellies full and lives protected, the Israelites went back to pursuing other gods. God punished Israel again. Israel repented and cried out to God.

And so went the deliverance-idolatry-punishment-repentance cycle (vs. 40-46), until finally, God had no other choice but to divorce unfaithful Israel (Jer. 3:6-11).

He used the Assyrians, one of the most brutal warrior nations in history, to invade, conquer, enslave and relocate the entire northern kingdom of Israel (II Kings 17). Having “disappeared” from history, the modern-day descendants of those ten “lost” tribes are unaware of their true identity even to this day.

Later, God sent the southern kingdom of Judah (mainly the tribes of Judah, Benjamin and Levi) into Babylonian exile (II Kings 24 and 25). Because they kept (at least physically) the true Sabbath, which is a special sign that identifies the one true God and His people (Ex. 31:12-18), the Jews were able to retain their true identity.

The Israelites were severely punished because they lusted after pagan customs, rituals, traditions and practices. As you can see, God does not take paganism lightly.

Why Paganism Is Wrong
Just why does God hate anything that resembles pagan customs? Is it possible to “whitewash” or “Christianize” pagan practices and make them clean? Is it okay to practice pagan customs as long as you “worship God”?

Notice what God says in Leviticus chapter 18. After rescuing Israel from slavery, God warned them not to practice the customs they had picked up in Egypt, or learn the ways, customs and traditions of the Gentile nations that they would encounter in the Promised Land (vs. 1-3). Instead, God commanded Israel to follow His ways (vs. 4-5).
