Hebrews mentioned lots of people who were faithful to God but yet did very bad things; David is mentioned although he committed adultery and had a women's husband killed, Rahab the prostitute is in there also, as well as others who committed serious sin. The Bible does not whitewash over the bad things that humans have done, even if they did it in the name of God.
How many of us have never sinned? You may feel some sins are worse then others. But to God, a sin is a sin and there are no varying degrees of it. However, even though we sin, we can still at the end of our lives, be considered an example to others for our faith. As long as we have life left, we can turn ourselves around, repent and come closer to God.
Jephthath showed remorse about his decision. Yes, God could have told him not to do it. But maybe he allowed it to teach Jephthah an important lesson, along with his daughter. As after all, she did not run away from being sacrificed did she? Perhaps she also felt God condoned her sacrifice. Pehaps the example was for others not to make the same mistake Jephthah and his daughter did? I don't know.
The point is though, whether it was a lesson or not, just because God did not stop it, does not mean he condoned the sacrifice. Also, just because Jephthah later was mentioned as being faithful to God, does not mean God condoned all his actions either. We know he did not condon David's sin, did he?
The bible is too ambiguous in Jephthah text to get the entire view of God's feelings about this practice, so we have to look at other scriptures in additon to this;
There are several verses that indicate that God is against child sacrifice. God expressly forbids it:
- Deuteronomy 12:31: You must not worship the LORD your God in their way, because in worshiping their gods, they do all kinds of detestable things the LORD hates. They even burn their sons and daughters in the fire as sacrifices to their gods.
- Deuteronomy 18:9-12: When you enter the land the LORD your God is giving you, do not learn to imitate the detestable ways of the nations there. Let no one be found among you who sacrifices his son or daughter in the fire...Anyone who does these things is detestable to the LORD, and because of these detestable practices the LORD your God will drive out those nations before you.
and its practice is described as evil:
- 2 Kings 16:3: He walked in the ways of the kings of Israel and even sacrificed his son in the fire, following the detestable ways of the nations the LORD had driven out before the Israelites.
- Psalm 106:38: They shed innocent blood, the blood of their sons and daughters, whom they sacrificed to the idols of Canaan, and the land was desecrated by their blood.
- Jeremiah 19:4-5: For they have forsaken me and made this a place of foreign gods; they have burned sacrifices in it to gods that neither they nor their fathers nor the kings of Judah ever knew, and they have filled this place with the blood of the innocent. They have built the high places of Baal to burn their sons in the fire as offerings to Baal - something I did not command or mention, nor did it enter my mind - Peace, Lilly
