I hate this response when it comes to God. People never think about the consequences of what they are stating when they make this assumption. You are saying that an omnipotent and omniscient God had no choice in the matter. You are saying that this omnipotent and omniscient God couldn't come up with any other ideas that would solve the problem.
I'm quite sure that if there were another way that it could be done,
He would have done so.
But no, He chose THAT way. If He chose THAT way, who are we to really argue?
Let's assume for a second, that you are the only human in existence. It gets pretty lonely, right? So you make yourself a robot. Let's assume you've the means and the know-how to make your very own robot complete with artificial intelligence (but not as smart as you) We'll also assume for a second that these robots can't kill you even if they wanted to. Let's say you decide to make multiple of them, because hey, company's nice, right?
These robots have AI, but they are not as smart as you, but yet after awhile, they start talking to each other, and then one of them turns towards you one day and goes "...why do you think you have authority over us? Who made you leader?" And you take that robot, shut him off, and disassemble him and the other robots gasp in horror and go "You killed him! Who gave you the right to do that!?"
What would your response be?
God made the Earth, and everything on it, and He also designed and made us. If He chose to flood the Earth... where do we get the
insolence to think we can question God on what He chose to do with His creation? He could snap His Holy Fingers at any time and wipe the whole world clean if He so desired. He could have done that at any time, but yet He didn't. He chose to flood it, but He gave a lot of prior warning, and made sure to save 8 people and a bunch of animals to "start over". He didn't have to, but He chose to.
You say "He could have done it another way" ... I'm sure He could have. But He chose not to, maybe because He didn't like the "other ways"? Maybe said "Other Ways" wouldn't have worked as well? Maybe the corruption was so great that killing everything on the planet was the only way to remove it?
What happens when you get gangrene? You either cut off ALL of the affected tissue, or you eventually die. One of the two. And to make sure you got ALL of it, you need to cut off some of the unaffected tissue too. If you have gangrene in your foot, you're probably going to lose your entire lower leg, because the doctor can't risk leaving any of that in your system. Are you going to sit on the operating table and go "Doc, is there really no other way? Can't we just more carefully scoop more of it out?"
He's going to tell you that your lower leg needs to be amputated, stat.
Of course we weren't there during the days of Noah... we aren't able to see just how much corruption was there. But the Bible
does say that "corruption and violence
filled the Earth". This sounds like it was pretty wide-spread and the only way to cleanse it was to kill everything. Thankfully for us today, He found 8 people and a handful of animals that were still clean and saved them. And even then, it didn't take too long until sin and corruption again started to rear its ugly head (Babylon was formed soon afterwards by Nimrod, one of the most evil people named in the Bible).
@FrumiousBandersnatch :
You've moved God's goalposts; knowing what would happen if choices were different is very different from what you described previously - having the intent that those things should happen, and having that intent frustrated. Are you now withdrawing the idea of God's frustrated intent?
It's complicated, to be honest. Yes, He knows all of the what-ifs ahead of time, but yet He also knows what He would like everybody to do, but yet again, Free Will. He refuses to break the Free Will rule. He knows what choices you will chose to do in your life, and He has a list of things He
wants you to do in your life. But, because of Free Will, He can't force you to do what He wants you to do.
It's... it's like watching a movie that you've already seen before. Ever do that? Let's say you're watching a movie, you already know how it ends, but yet through the movie, you ponder "What if this person had just made that phonecall? What if she turned around 30 seconds earlier and saw the killer coming up to her? What if she locked her door?" as you watch the movie, even though you already know what's going to happen.
Using an abortion as I did before as a parable, a woman gets pregnant, but aborts the child. God knows that she is going to abort the child, but does that stop Him from pondering what He would have used that child for? Would that stop Him from knowing what that child would have done, if she had
not aborted the child?
