Then we don't need to be God in order to determine if God's actions are immoral.
One day, not too long ago, my five year old twins did something I told them not to do. As a result I sent them both to the room they share to sit on their bed and think about what they did and why it was wrong and why they were being punished. I closed the door and stood outside to listen to what they would say.
They started talking to each other and said things like "daddy is mad at us" and "we don't have a daddy anymore" and "he is being mean to us" and "when mommy gets home we are going to tell her daddy was mean to us and he is bad daddy".
Now to be sure, my children have a rudimentary understanding of morality. They know they should share their toys. They know they should not lie but tell the truth. They knew they should obey me and their mother. I even asked them if what they did was wrong when they disobeyed me and they confessed they knew that what they did was wrong.
Nevertheless they judged me to be a bad daddy when I punished them for disobedience. Although they knew right from wrong, they were not in a position epistemically to know that me punishing them was intended to bring about a greater good for them, i.e. it was to help them remember not to play where I cannot see them but to play where I can see them so that they are safe. Their ultimate well being was what I had in mind when I brought them in and told them to go to their room. I wanted them to learn to listen to me because I know I have their best interest in mind. I know of the pedophiles that prey upon unsupervised children. I know of the people driving cars that do not pay attention to where they are driving while texting that have hit children and run them over and killed them. I know of all the insects and wild dogs that are out there that could hurt them.
They don't know what I know. They can't know what I know. I am over thirty years old. They are five. I'm an adult they are a child.
They thought me bad for punishing them. They did not know what I knew.
Likewise we as adults are sometimes like my children. We don't know or see the big picture. We see God punishing people or allowing certain things to happen and we assume He is bad or mean and if all we did was pluck out of the Bible those verses that talk about these things it is no wonder we would view Him as bad bloke.
When I was a child I thought my dad was very mean to me sometimes and overbearing. I thought he was a tyrant and treated me the way he did because he didn't Iike me or didn't want me to have fun. Now that I am a man with children of my own, I realize he did what he did many times because he loved me and wanted me to renounce those things he knew would ultimately be my undoing.
Then I did not know it or see it. Now I do.
I have a different view of God than you do. This is partly because I find many more verses in the Bible that show God is merciful, compassionate, longsuffering, and loving than those that speak about His wrath and vengeance.
If I wanted to I could simply ignore any and all portions of the bible where God is said to be wrathful or where He does things that I can't understand or think are contrary to Him. But I dont. I don't because I believe that I should accept the whole counsel of God and that it is all God's word even the parts I don't get.
I choose not to be like Thomas Jefferson who felt free to cut out of the Bible those verses he did not agree with and make his own.
Idol worship is easy. Worshipping the One True God requires obedience.
