This is the start of the legend that Jesus spent Saturday on the 'harrowing of hell'. (1 Peter is a pseudepigraph, for what it's worth.)"atrocities" -- would be that way...except if...
... -> God simply reverses all death, and and gives everyone not having heard the gospel a chance at repentance:
18 For Christ also suffered once for sins, the righteous for the unrighteous, to bring you to God. He was put to death in the body but made alive in the Spirit. 19 After being made alive, he went and made proclamation to the imprisoned spirits—
....
For this is the reason the gospel was preached even to those who are now dead, so that they might be judged according to human standards in regard to the body, but live according to God in regard to the spirit."
1rst Peter chapters 3 and 1 Peter 4 NIV
The accusation is that God does things on earth that are atrocities, even should [his] conscience catch up later.Ergo, the objections about genocide, atrocities, and so on just simply assume God isn't doing what the bible says He is doing....
What kind of a God says stuff like ─
Deuteronomy 7:1-2 “When the Lord your God brings you into the land you are entering to possess and drives out before you many nations...then you must destroy them totally. Make no treaty with them and show them no mercy." (and again at 20:16)
or commands Moses to say to his army ─
Numbers 31:1 17 Now therefore, kill every male among the little ones, and kill every woman who has known man by lying with him. 18 But all the young girls who have not known man by lying with him, keep alive for yourselves.
or engineers human sacrifices to [him]self such as Jephthah's daughter (Judges 11) or the 'sons of Saul' (2 Samuel 21) ─ let alone Jesus.
Why on earth was the 'gospel message' withheld from Adam? From Abraham? From Moses? From Solomon or David?In other words, that's a 'god' unlike the one in the bible, when people are just killed and it's the final death, and they didn't even hear the gospel message or such.
And who was Jesus to tell the Jews anything? He no more fitted the Tanakh's concept of a messiah than I do, and instead of being savior of the Jewish nation he began two millennia of often murderous Christian antisemitism, starting with the author of John.
That's snakeoil salesmanship ─ You're doomed and only I can save you: all you have to do is kiss my ─ ahm ─ foot. Oh, and pay the man over there.You can see that version of 'god' was (accidentally) a strawman, in essence. But, that's really good news -- it shows how very gracious He is, as illustrated here:
