I have great fondness and appreciation for the simple argument (“freewill”) that a moral being is not completely free if not given an equal ability to choose evil. The problem that I have with that argument is that if God is not able by virtue of His nature to tempt the creature/agent, which we know absolutely He is not, then it boggles my mind how a free moral agent who is created in a position and nature that is declared as good by God could even conceive an irrational desire for anything but fidelity and loyalty to the creator of all things that the creature has ever known.
Well then you're insisting an interpretation about what good has to be. That's fine. We all do that but we do need to have scriptures provide how we're thinking.
So you're agreeing the devil, Lucifer, and MAN, Adam and Eve were defined good. So how can they even have even a notion or even put together an imagination to doing wrong.
Various ways to answer this. 1) I think you should know then.....it demonstrates they were in fact TOTALLY FREE to choose. There was no ordaining them TO SIN for that would make THEM even not good and God has defined free moral agents would be a good thing and a necessary way to make them. When he made them this way he defined them as GOOD.
I'd say too that God created all beings with the capacity to be creative. I'm not talking creative like where God creates worlds with power but creative in how we also use the word....imaginative or to seek to have the capacity to look beyond things seen and develop a vision within one's self of things which are different. Let's say God created MAN and did tell him to replenish the Earth and subdue it. God didn't make all the Earth like the Garden of Eden.
That was the home base God gave them that to start off with. God created MAN to be creative and develop things and we could say it was good that God gave MAN to capacity to be creative. His imaginative capacity however needed to be kept in check and we see this exhortation in Phil 4 .,,that we're to dwell only on thoughts which are true, lovely and pure. But God did make MAN free to choose! So you're question is how could they have had the capacity to even have a notion of evil? Again for the reason that a part of being good is they could be imaginative. They were required though to keep that in check.
Now with Satan in the beginning what thoughts did he choose to develop within himself. I think he actually originally agreed God was good but here's the thing....maybe he's just too good. Maybe being so loving perhaps he's like a wimp and would never stand up towards one resisting him. Therefore he envisioned and asked wouldn't this be a greater type of strength if one who wouldn't keep the things of LOVE? So it was good that he, angels and MAN were created with an ability to be imaginative but they must keep it in check and no go against the things of LOVE. Lucifer however threw caution to the wind and and crossed the line into rebellion for he didn't allow this to be a part of his imaginative process...that he would be cast out of heaven.
He (Jesus) replied, “I saw Satan fall like lightning from heaven. Lk 10:18
He didn't consider that LOVE (God) would have to stop him for he would not be love if he didn't. So I ask doesn't that answer your question? A part of good is to have the capacity to imagine and it wouldn't be good for beings not to have it....that's what LOVE gives....but it must be kept in check and be balanced and it's up to the individual to do so.
This is even true in our everyday lives. Eating food is good and God meant it to be enjoyable. We could say other physicals desires we have as well BUT you must keep that which is good in check and be tempered with wisdom.
