In that case, I would say he was not sinning by disobeying his father. God's word is meant for parents who are godly and good examples > to obey them by following their good example, not only doing what they say to do.
And she insisted that he do what he vowed to do. But it says she lamented her virginity . . . not loss of life; but she might have understood she was lamenting her virginity because of the fact that she would die.
I consider there was a way to keep her alive, perhaps by substituting a lamb to redeem her. But, still, may be she did not marry, which would be equivalent to not living, as far as that culture was concerned. It does not directly say he killed her. But I admit it is possible, but not what God required . . . in such a case.
But he did vow that whatsoever he first saw, when he returned, this he would sacrifice to the LORD; and I see how he could have meant for the LORD to decide and control what he would see first. So, I would not say he necessarily acted in haste, in case he intended for God to decide and control. God was in control, knowing how things would go.
So, I am open. But I consider God had him do something other than kill her. In any case, he could pray and make sure with God. If he didn't make sure with God, that would have been acting in haste, I think.
Abraham understood that the LORD would resurrect Isaac so Isaac could be used to complete the promise God had already given Abraham > Hebrews 11:17-19. So, yes it is clear to me that Abraham actually did understand that the LORD was telling him to kill and burn Isaac as a sacrifice. But it appears God overruled His own order, to show what He really considers to be right from wrong.
Possibly, the boy did not have a moral compass, about obeying parents. He just was going along because that was all he knew to do, at least to some extent. But then he did escape > however he processed in himself to do that, after going along so long, I don't know. But I trust God delivered him.
But this is the sort of thing which Satan's kingdom can rig, in order to make it look like there is no God. This could, then, be one sample of how evil is so horrible and anti-God and anti-love, that evil has people do stuff like this, in order to make God and love look bad. So, in any case, it is wise not to ever allow evil to decide how we see things.
He stopped Abraham; so He was not approving that.
How does one know? There are people who do not have ways to know, I would say; except, the Bible says God shows things to people > Romans 1:19-20. But Jesus says there are ones who do not know, yet they will receive stripes > Luke 12:48.
What I consider is may be the person does not know about specific items, but still on the overall the person has rejected God; and so the person gets stripes because of rejecting God, but maybe not for what the person did not know. In any case, there is no excuse.
Now, you identify as an atheist; yet here you are busy with a discussion of right from wrong . . . on things which likely would make little difference if all were driven only by evolution. So . . . in case there really is God > this is why you manage to somehow get concerned about morals and good versus evil. Because if evolution was the highest driver, it could be acceptable for a lot of humans to be removed so there would not be such ruin which humans cause. That could be better for survival of humans and other living beings.
But because God has a use for even evil people, and His redemption working, He has managed things so even unbelievers feel very concerned for the well-being of antisocial and destructive people, so we are putting them in prisons and making major sacrifices to keep them.
"where there is no law there is no transgression" (in Romans 4:15).
But a person is still liable for if the person rejects God. Because we are
"without excuse", we have in Romans 1:20. One might not be held accountable for not doing a certain law thing, but still how that person is in one's character is going to be evaluated on the day of judgment > Galatians 6:7-8 > speaks to this, I would say. In this life, each of us is becoming more and more how we will be when we die. And then we will reap so much more of this. In a way, each of us will be our own consequence, of how we will be for all eternity. So it is wise to invest in becoming like Jesus!
So, in my opinion, the do's and don'ts of laws is not the first priority.
I think the concern is deeper, in such a case, than do or do not obey the father. You have the case of when the midwives were told by an authority figure to kill all the newborn male Jewish children. And the LORD rewarded them for disobeying the Pharaoh.
I think of Hebrews 2:14-15. This is talking about one of the things which Jesus was accomplishing by dying on the cross >
"Inasmuch then as the children have partaken of flesh and blood, He Himself likewise shared in the same, that through death He might destroy him who had the power of death, that is, the devil, and release those who through fear of death were all their lifetime subject to bondage." (Hebrews 2:14-15)
So . . . Satan abuses his children with
"fear of death".
So, indeed this is wrong. Hebrews 2:14-15, then, I would say, agrees with you!!
