You're veering off my point, but I'll entertain your point for a moment. After that, we'll get right back to my point.
Either no one knows the mind of god, or everyone knows. You can't have it both ways. Since, by an accepted definition, God is infinite and we are finite, I'm gonna guess the former. But, some may say - "We got the scripture that gives us an understanding of God.". If the message is so clear, concise, and with no ambiguities or vague areas, (like one would expect from an all powerful deity who wanted to get his message across to everyone), we wouldn't have 14,000 or more differing denominations, reading the same message and coming up with all kinds of differing interpretations. And I'm only counting those who are sincere in their faith and learning.
This infinite and all powerful god, (who is not puny, according to some), wasn't able to change their hearts in an instant, like he did to Saul/Paul, who was touring the land and killing Christians at the time of divine intervention. (BTW What happened to Saul's free will? .... but that's another topic altogether) Instead of that, your god chooses a slow and tortuous death to every human being and animal on the planet. In any other context, how would this not be considered cruel and unusual punishment? How would it not be considered evil?
We can know the character of God---His mind is far beyond our comprehension. How can a flea understand the mind of a human??
Saul wasn't forced into changing. He saw the error of his ways and changed course. He could have chosen to remain as he was.
And what makes you think that those people were not given every opportunity to choose differently, also??
(Jud 1:14) And Enoch also, the seventh from Adam, prophesied of these, saying, Behold, the Lord cometh with ten thousands of his saints,
(Jud 1:15) To execute judgment upon all, and to convince all that are ungodly among them of all their ungodly deeds which they have ungodly committed, and of all their hard
speeches which ungodly sinners have spoken against him.
God always warns, and it wasn't a spur of the moment thing--Enoch lived a long time and he preached and warned. Unfortunately---God doesn't force you to choose the right way. He may, at times, alter circumstances and force you to think--like Jonah in the whale--but Jonah could still have been defiant and not done what was asked.
(Eze 33:11) Say unto them,
As I live, saith the Lord GOD, I have no pleasure in the death of the wicked; but that the wicked turn from his way and live: turn ye, turn ye from your evil ways; for why will ye die, O house of Israel?
Slow and torturous death??---Don't know about that- --When these tsunamis hit, it's over pretty quickly.
Bottom line is what we have chosen to believe about God's character. I believe Him to be just, long suffering, loving, and does everything He can in order for us to choose Him. If you wish Him to be a bad tempered, vindictive, mean child
--it's your choice. You can look at the story of Noah and think what you do, or see it as He tried everything and warned and pleaded and they were so evil He had to destroy them. Why He choose water I can't say. The final end will be by fire. As for having empathy for Noah when he had to endure the evil of that generation--you ever been around a real mean and evil person??---I have, I was raised by one. They are having a ball inflicting misery on others. What would have been so wonderful about God allowing such a world to keep on living in such an evil way?? Raising their children to be as evil as themselves?? How is that a good thing?? You would have condemned Him for that ad you condemn Him for destroying them.
