those verses are not natural they are Spiritual.
The opposite of "natural" is not "spiritual."
The opposite of "natural" is "unnatural."
The laws given to Israel that were intended ONLY for Israel (such as the dietary laws) are both natural AND spiritual laws. They have a natural application and a spiritual one, but ONLY for Israel. Not for any other people.
The woman caught in adultery had committed an offence worthy of death by stoning according to the Jews. But Jesus said those without sin cast the first stone.
Jesus never repealed the death penalty, no, not even when the "adulteress" was brought before him.
None of us are without sin,
The only logical conclusion to this argument is that no one should be punished ever for committing any crime at all.
God knows that man is sinful, and yet He still expects justice to be dealt to those who break the law. If someone steals, He expects restitution. If someone harms someone physically, He expects corporal punishment. If someone if someone murders or commits adultery, He expects the death penalty.
God's ways are just, loving, and merciful, and if there's any conflict in what a man believes with what He says, let God be true and every man a liar.
The death penalty is merciful. It shows mercy to the victims, while at the same time punishing the guilty. By excluding the death penalty from punishments for crime, you show mercy to the criminal, while punishing the innocent for being victims.
and we have no right killing another,
Exodus 22:2, Deuteronomy 17:7, and Acts 25:11 prove you to be wrong, and there are plenty more verses like those.
Stoning is just one form of punishment that could be used.
There's also...
Old Sparky (electric chair)
Old Rusty (lethal injection with no anaesthetic (also no reason to clean the needle))
Old Stabby (knife for stabbing to death)
Old Knotty (hangman's noose)
Firing Squad
Pit (or pool) full of hungry animals (such as piranhas, lions, wolves, etc)
Burned at the stake (appropriate for arsonists)
Thrown off a cliff (used in B.E.'s book
The First Five Days for abortionists convicted of murder)
Spacing (or "airlocking", useful for capital criminals in space or deep underwater)
And of course, guillotine.
And to even think of killing a child is sickening!!!
More appeals to emotion.
If a child commits a capital crime, he should be put to death. If he does not commit a capital crime, he should not be put to death. It's as simple as that.
The Law applies equally to all men, women, and children.
It's not "normal" to kill
It's perfectly fine to kill someone who is trying to kill you or another innocent person if it's the only way to stop them, and it's perfectly fine for a government to execute criminals worthy of death.
