Curiously I’m asking this. It has no pertinence to the heart of the conversation. You’re saying there is only your God. No other gods exist?
You’re correct that similarities don’t in general require derivation. But that’s not how they determine derivation, which is called syncretism, in case you didn’t know. It’s if the ways they are similar are key or major events to the story.
First, the problem is that you’re jumping to the two gods would be at odds. If they are both perfect than what logically follows, provided something could be perfect, is that they would want for the same thing. Provided that wanting anything is a trait a perfect being would have. So then both Gods would realize that collaboration is best. But is collaboration necessary? If they are both all-powerful and perfect they can create instantly without fatigue. So would there be no point to both of them existing. It depends on what the purpose and need of any God existing. Since the first God would instantly realize this causal chain. It would also instantly know that there is no need to create another equal god. But whether or not one should has no bearing on the ability to be able to create such.
> "What about energy? matter? gravity? Just wondering."
Well we just don’t know this for certain. Gravity is a force that only happen when there’s particles with mass. This is why light (photons) can travel as fast as they do. It’s because they are particles that don’t have mass. Matter came about from particles forming from the big bang. Time isn’t even determined to only exist within our universe. Any certainty claims cosmology makes are based off of the laws of how our local universe operates. Once the universe dies the laws of physics no long hold up. The only thing we’re left with is energy. I know energy is only rerouted never destroyed. Since we don’t know what happened before the big bang or what happens after the death of a universe we just can’t say. On top of that, energy isn’t an agent or entity. It’s only a force. Your God is thinking being with I’m assuming some sort of collectiveness somewhere in the cosmos. Perhaps irrelevant to get into that part.
> "I don't need to. If God granted to man (or, as is my opinion, free will is a necessity [but that's a different conversation]) free will, then if God interferes with that free will, then it's not free, and it's not will. Interference is abrogation. I'll take a stab at an analogy, though it may have its weaknesses: If I give you a car, but I refuse to let you get in it or drive it, then (1) I didn't really give it to you, (2) it's not yours to use, and (3) the gift is worthless."
If we truly had free will why does God manipulate us with threats of hell? The entire Old Testament is God affecting our free will through some type of manipulation or interference. As for your scenario I have to poke at the holes. I think well have Will, it’s just not free nor can it be. Since we all function from our experiences and how our biology, we are slaves in different degrees as to what we choose to do. Let’s go back to the car scenario. A more apt scenario would be God gives you a car (will) most of the time you drive in accordance to your experiences. Occasionally, (what Christians believe) you ask God for help and he’ll reach over and adjust your steering or point left or right. Like a side seat driver. So as you see we don’t have or actually need freedom to be a factor part of ‘will’.
God’s knowledge of the future interferes with us and Satan because he is making us perfectly the way he wants us to be. So if he knows that making us one way will give us a certain future. Then we have to reason that because we sin its how God wanted us to be. Satan rebelling is what God intended because he knows all way to have created Satan to where he wouldn’t rebel. If we look at actual reality as to how people act it’s almost paradoxical to what the bible says God wants. Which means either God isn’t one of the attributes (perfect, all-knowing, all-powerful) we used to describe him or he made us to sin and then wants to punish us with hell for being what he made us to be. I think you and I will have to trudge through free will to resolve this after all. I’ll start with this. Logically if God is all the descriptors we’ve given him, all-knowing, all-powerful and perfect, than he would create us in the way he wants and we would be that creation to the Tee. If we are exactly what God wants than we have no say so in how we function because we are how he wants us to be. Therefore, we have no free will. Will perhaps, but not free. Now what if God created us to specifically have free will? Since he’s all-knowing he would automatically know what we would do with it. Since God knows we will do the opposite of what his will is. Then by extension he created us to fail or disobey. The problem believers face is that they can’t escape a God having these three qualities necessitates that anything He makes is exactly how He wanted it to be. If your creation fails in its functioning at any point and is less than what you wanted than you cannot be all three things. Side question; is there some kind of short hand for perfect, omniscient, omnipotent?
