I'm not a christian, but I grew up in a Baptist household, so I have at least a passing understanding of the Bible. Lemme know if I got any wrong.
If I'm understanding the bible correctly;
God Created heaven and Earth, Including Mankind and Angels
God is all-knowing and all-powerful
Relevant to this discussion, God created Lucifer and all the angels who sided with him.
God made Man in His image, and ordered the angels to serve them.
Lucifer, prideful of his own beauty, and envious of God's (at least perceived) favoritism of Man, and of God's position, started a rebellion in heaven and was/will be cast down into the lake of fire(aka Hell).
lucifer later tempted/took the form of the Serpent in the Garden of Eden and tempted Eve to eat of the Tree of Knowledge.
my conclusion: God, with full knowledge of what lucifer would do/become created him and set him on the path that led to his downfall, and to the Sin of Mankind.
Or to put it more simply; God created Sin through his foreknowledge of what Lucifer would become.
I'm not trying to start a shitstorm here, but this is the logical conclusion that I find myself at.
Any Christian pedes wanna poke holes in this for me?
First, you tell me if creating beings with no freewill is worth creating in the first place.
Absolutely, freewill is paramount (insert vague reference to AI here), but I'm not trying to pass some moral judgement, just trying to figure out if I have this correct. If God created Lucifer with foreknowledge of the sin he would introduce into the world, did God create sin?
God created the option/freedom to sin. Sin is just a voluntary distancing from the Creator. You can choose to go to Him or not, but He wants you to choose Him. That is the whole point.
Also, what would be the other option? To not create Lucifer? Eventually you have to accept that to truly be creating beings with genuine freewill, something like Lucifer would be spawned on its own volition.
