As a firm Believer/Christian, while it is my personal duty to humbly, and lovingly try to divide the Word, this question is not new, and this question borders on mild dishonesty/misguided thinking. (Not directly accusing you personally).
9/10 when people ask this question, they either have not read fully, or forgotten how those people in the Old Testament behaved. For starters, most of the surrounding areas of Israel were offering their children/infants onto bronze/metal smoldering, burning, man-made statues/alters in hopes their crops would receive rain. They were performing unspeakable acts with animals/beasts of the field, perpetuating generations of incestual (note: Not akin to sanctioned biblical marriages along the fathers geneology) relationships, some regions carried out ceremonies that were extremely unsanitary, etc. there’s indeed more.
there’s a chunk in the Levitical laws where the instructions start with “You shall not” followed by “unlike the [insert foreign surrounding nations names]”.
As far as the all-loving aspect goes, let me ask you, if God didn’t do it, then what does that make him? Uncaring? Unjust? Indifferent? To which people will again turn around and point their fingers at God yet again for not doing something. But then people get up in arms because “He didn’t have to go that hard jeez”.
To add, the Israelites were warned for a period in the ballpark of 40+ years to stop adopting those same practices they were strictly told NOT to do, and they too were punished. Both the Babylonian and Assyrian invasions were direct prophecies involving their judgement.
I think people forget that Love and Justice run deeply together when we’re talking about God’s attributes. For some, they simply want the love aspect. Me personally? I think BECAUSE God is just, he is loving.
And yes, there’s the “well why hasn’t he flooded the earth, or caused another disaster like that, or brought on judgement like that? With all this suffering and injustice going on today?” To which I say, in the very last book, it deals with the “why hasn’t God done anything yet?” To which I’ll also say, in both of the above stated instances of judgement, God was patient. He is indeed still patient now. But when time is up, it is up.
Thanks to the common grace of providential common law we have a handful of modern nations who aren’t as bad as they could possibly be, but the continued suffering and hardships of humanity isn’t God’s fault. It’s ours. And people can only cry out now because the “now” is all we know as time-bound beings.
Rant over I guess.
