I don't think it was ever morally good to stone children--no matter their supposed transgression. That's not right today and it was never right.
Indeed, the Lord takes
"no pleasure in the death of the wicked, but that the wicked turn from his way and live." (Ezekiel 33:11)
"But in accordance with your hardness and your impenitent heart you are treasuring up for yourself wrath in the day of wrath and revelation of the righteous judgment of God," (Romans 2:5)
Wrath is worse than getting stoned. Stoning can stop a person from storing up more. Being love-dead in sin is worse than being killed, so one can go on in a living death and with others become
"worse and worse, deceiving and being deceived." (in 2 Timothy 3:13) You can not talk your way out of this.
But, like I offer, Jesus would say let the one without sin cast the first stone >
"all have sinned and fall short of the glory of God." (in Romans 3:23) And we might see through this how God does not desire for anyone to be short of His own glory. So, not only is it wrong to live in the stoning realm or much worse, but it is wrong to not be sharing with God in His own glory, in the ruling of His own peace in our hearts > Colossians 3:15 > yes, our Father desires to personally rule each of His children in His own peace > this is a basic of living as a child of God . . . a basic for those who teach the Bible, I would say.
"And let the peace of God rule in your hearts, to which also you were called in one body; and be thankful." (Colossians 3:15)
So, if you really believe something is wrong, let's talk about what is right, instead, for comparison. God is not distant and impersonal, but personally rules those who are His obedient children, sharing His own peace with us . . . His own harmony of Himself, sharing His own self with us, then.
But in the New Testament we do have how the wrath of God is upon the children of disobedience. In the Gospel of John, John the Baptist says
"the wrath of God abides on" the unbelieving.
"Therefore put to death your members which are on the earth: fornication, uncleanness, passion, evil desire, and covetousness, which is idolatry. Because of these things the wrath of God is coming upon the sons of disobedience, in which you also once walked when you lived in them. But put off these also: anger, wrath, malice, blasphemy, filthy language out of your mouth." (Colossians 3:5-6)
So, yes there are children who are of disobedience to how our Father has us love. And there is wrath because of their evil stuff within them. It will go somewhere, not to "Heaven". Actually, in Jesus we already have Heaven's love shared with us >
"Now hope does not disappoint, because the love of God has been poured out in our hearts by the Holy Spirit who was given to us." (Romans 5:5)
So, of course it is wrong to do what could qualify a person to get stoned. They are missing out on so much. The fact of all they are missing out on can help to show how they are wrong, to do the exact opposite. And wrath of God is worse than getting stoned. And the lists above can help us to see what qualifies someone for God's wrath. But Jesus on the cross shows how this does not give God pleasure, but He would share His own Treasure Jesus with us, instead, so with Jesus we share as His family in His love's
"rest for your souls." (in Matthew 11:28-30)
Or, a person can have God's personal communication of His resistance >
"God resists the proud" (in James 4:6 and also in 1 Peter 5:5).
One way or the other, God is personally proving Himself to each of us, by His personal sharing and guiding in His peace, or the personal communication of His resistance.
"He who loves his life will lose it," Jesus guarantees, in the Gospel of John 12:25. And ones rebelling against this lose their lives in much more painful and worse and dragged-out ways, than being stoned. So, I see how for an incorrigible person, dying quickly could be merciful, but yes God does not take pleasure in that, but would that the person's evil selfish personality die and the person become like Jesus and discover how to love as family tenderly and caringly >
"without complaining and disputing" (Philippians 2:14-16) which are degrading and anti-love things which can keep the suffering and torment of sin going and growing so people and therefore their marriages
"grow worse and worse" in their arguing and complaining and love-dead bitterness and frustration.
God's desire is to put to the death the evil, transformation however seems to be his MO. Christ tells us to follow him we need to deny our self. "Self" is all that seeks to move away from God. The law demands death and that death has been satisfied through Christ's death on the cross, it also is repeated in our selves in baptism where we die to self and rise up in New life.
So the laws gets it's death and God then sends his life.
Thank you
