Destruction of Canaanites
A popular criticism of the Bible made is that God was unjust, unmerciful, and cruel by ordering the destruction of the Canaanite nations as seen in the books of Joshua and Judges. But logically the United States was forced to bomb Hiroshima and Nagasaki during World War II, and to kill many German Nazis in order to free the world from tyranny and save the lives of innocent people, so therefore there can prove mitigating circumstances where an act of apparent destruction is necessary for a greater good to save lives. Thus it is important to ask the question no one ever seems to ask here, "Why did God destroy the nations?"
Why the Destruction?
Obviously if God was just wiping out nations because He felt like it or for the vague accusation of "idolatry" there would be little ethical justification for worshiping such a God. Moreover, if He stated why He was doing so only after the fact it would come across as a lame attempt to justify His actions. For there to be a horrible wrong He was confronting one would expect to see this referenced both before the destruction and constantly throughout the Bible... which is exactly what we see.
God told Moses and the Israelites before they ever entered Canaan a list of reasons for why the nations were being destroyed (see Leviticus 18 and Deuteronomy 18), and that list included the horrific crime of child sacrifice to the Canaanite idols of Baal and Molech.
|“||Leviticus 18:21 And thou shalt not let any of thy seed pass through the fire to Molech, neither shalt thou profane the name of thy God: I am the LORD...
Leviticus 18:24 Defile not ye yourselves in any of these things: for in all these the nations are defiled which I cast out before you:
Deuteronomy 18:10 There shall not be found among you any one that maketh his son or his daughter to pass through the fire, or that useth divination, or an observer of times, or an enchanter, or a witch,
Leviticus 20:1 And the LORD spake unto Moses, saying,
Deuteronomy 12:30 Take heed to thyself that thou be not snared by following them, after that they be destroyed from before thee; and that thou enquire not after their gods, saying, How did these nations serve their gods? even so will I do likewise.
Preventing Spread of Practice
God furthermore explicitly forbade Israelites from marrying into the nations knowing that if they did so they would adopt the horrible practice of murdering their own children so that it would spread worldwide. It appears Israel was beginning to adopt this horrible practice even before they entered Canaan, see Numbers 31.
|“||Exodus 23:32 Thou shalt make no covenant with them, nor with their gods.
33 They shall not dwell in thy land, lest they make thee sin against me: for if thou serve their gods, it will surely be a snare unto thee.
Exodus 34:11 Observe thou that which I command thee this day: behold, I drive out before thee the Amorite, and the Canaanite, and the Hittite, and the Perizzite, and the Hivite, and the Jebusite.
Deuteronomy 7:2 And when the LORD thy God shall deliver them before thee; thou shalt smite them, and utterly destroy them; thou shalt make no covenant with them, nor shew mercy unto them:
Deuteronomy 20:16 But of the cities of these people, which the LORD thy God doth give thee for an inheritance, thou shalt save alive nothing that breatheth:
Israel deliberately disobeyed God's commandment to destroy the nations, and did end up adopting the practice of child sacrifice.
|“||Psalms 106:28 They joined themselves also unto Baalpeor, and ate the sacrifices of the dead.
29 Thus they provoked him to anger with their inventions: and the plague brake in upon them.
30 Then stood up Phinehas, and executed judgment: and so the plague was stayed.
31 And that was counted unto him for righteousness unto all generations for evermore.
32 They angered him also at the waters of strife, so that it went ill with Moses for their sakes:
33 Because they provoked his spirit, so that he spake unadvisedly with his lips.
34 They did not destroy the nations, concerning whom the LORD commanded them:
35 But were mingled among the heathen, and learned their works.
36 And they served their idols: which were a snare unto them.
37 Yea, they sacrificed their sons and their daughters unto devils,
38 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.
39 Thus were they defiled with their own works, and went a whoring with their own inventions.
40 Therefore was the wrath of the LORD kindled against his people, insomuch that he abhorred his own inheritance.
Jeremiah 32:34 But they set their abominations in the house, which is called by my name, to defile it.
2 Kings 21:3 For he built up again the high places which Hezekiah his father had destroyed; and he reared up altars for Baal, and made a grove, as did Ahab king of Israel; and worshipped all the host of heaven, and served them.
2 Kings 17:16 And they left all the commandments of the LORD their God, and made them molten images, even two calves, and made a grove, and worshipped all the host of heaven, and served Baal.
God Punishes Israel for Child Sacrifice
God's constant punishment of Israel, including the Babylonian captivity, was in large part because they insisted upon child sacrifice to Baal and Molech.
|“||Ezekiel 16:20 Moreover thou hast taken thy sons and thy daughters, whom thou hast borne unto me, and these hast thou sacrificed unto them to be devoured. Is this of thy whoredoms a small matter,
21 That thou hast slain my children, and delivered them to cause them to pass through the fire for them?
2 Kings 23:10 And he defiled Topheth, which is in the valley of the children of Hinnom, that no man might make his son or his daughter to pass through the fire to Molech.
Jeremiah 7:30 For the children of Judah have done evil in my sight, saith the LORD: they have set their abominations in the house which is called by my name, to pollute it.
Ezekiel 23:36 The LORD said moreover unto me; Son of man, wilt thou judge Aholah and Aholibah? yea, declare unto them their abominations;
Ezekiel 20:31 For when ye offer your gifts, when ye make your sons to pass through the fire, ye pollute yourselves with all your idols, even unto this day: and shall I be enquired of by you, O house of Israel? As I live, saith the Lord GOD, I will not be enquired of by you.
While critics will likely still jump at the opportunity to attack the God of the Bible over this subject, it should be abundantly clear that God was attempting to destroy the Satan-inspired practice of child sacrifice (see 1 Corinthians 10:20, behind idols are devils). It may well be this was the early origin of today's abortions. God was trying to destroy the nations that wholly engaged in child sacrifice to rid the world of a horrible, horrible sin. One could very well argue God was more justified in doing so than America was in bombing Hiroshima and Nagasaki during World War II, since rather than trying to stop world domination, He was trying to stop the domination of the world by child sacrifice.
Ultimately, only God alone is truly ethical and wise; only God is without sin. Human beings will attempt to justify their own evil actions and lifestyles, including by attacking the just God who condemns those actions. God is the judge of whether child sacrifice is wrong and how wrong it is. We can only get a glimpse of how God is justified and what the depth of His moral reasoning is, but I would hope most people in seeing the above passages can begin to recognize how completely justified God will prove to have been regarding His actions in this matter.
