Scripture isn’t clear how sin came to be (to my knowledge, although I don’t know all of scripture perfectly). But, it is clear how it started, and who started it. Here is my personal opinion, based on how I understand scripture.
We see that Lucifer, who was once one of the Arch Angels (scripture calls him the angel who “covered” the throne of Elohim (God)), and he was made perfect in many ways.
Isa 14:12-14 tells us how Lucifer fell, and why he fell. It was due to pride.
12 “How you have fallen from the heavens, O Hĕlĕl, son of the morning! You have been cut down to the ground, you who laid low the gentiles!
13 “For you have said in your heart, ‘Let me go up to the heavens, let me raise my throne above the stars of Ěl, and let me sit in the mount of meeting on the sides of the north;
14 let me go up above the heights of the clouds, let me be like the Most High.’
Eze 28:11-19 tells us how he fell, how he was made, and what he did.
11 And the word of יהוה came to me, saying,
12 “Son of man, take up a lamentation for the sovereign of Tsor, and you shall say to him, ‘Thus said the Master יהוה, “You were sealing up a pattern, complete in wisdom and perfect in loveliness.
13 “You were in Ěḏen, the garden of Elohim. Every precious stone was your covering: the ruby, topaz, and diamond, beryl, shoham, and jasper, sapphire, turquoise, and emerald and gold. The workmanship of your settings and mountings was prepared for you on the day you were created.
14 “You were the anointed keruḇ that covered. And I placed you, you were on the set-apart mountain of Elohim. You walked up and down in the midst of stones of fire.
15 “You were perfect in your ways from the day you were created, until unrighteousness was found in you.
16 “By the greatness of your trade you became filled with violence within, and you sinned. So I thrust you from the mountain of Elohim, and I destroyed you, O covering keruḇ, from the midst of the stones of fire.
17 “Your heart was lifted up because of your loveliness, you corrupted your wisdom for the sake of your splendour. I threw you to the earth, I laid you before sovereigns, to look at you.
18 “You profaned your set-apart places by your many crookednesses, by the unrighteousness of your trading. Therefore I brought forth fire from your midst. It has devoured you, and I turned you to ashes upon the earth before the eyes of all who see you.
19 “All who knew you among the peoples were astonished at you. Waste you shall be, and cease to be, forever.” ’ ”
Now, with this as background, here is my theory.
Scripture defines sin as breaking the law of Elohim (1 John 3:4):
4 Everyone who commits sin also breaks the law; sin is the breaking of law.
There is, from a scriptural perspective, only one law, and that is the Torah. Torah consists of the first 5 books of the Bible, as written by Moses. However, since Torah is the baseline of everything in scripture, and since Torah is the measuring stick (that which everything else is measured against) of righteousness, and of loving Elohim and our neighbours, we can easily say that Torah is all instructions in the Bible, since every instruction/law after Deuteronomy, is merely an explanation of an existing law from Torah. There is no new laws after Deuteronomy, since Torah is the standard, perfect and complete, as Father wants it.
So, based on this definition of sin, we can easily see that sin isn’t a thing on its own, but rather a lack of something. A lack of keeping the law of Elohim. So, just like cold isn’t something in itself, but merely the lack of heat, we can see that sin is not something in and of itself, but rather the lack of keeping to the law of Elohim.
Therefore, while Father did create “sin” as a direct result of breaking the law, He did not create sin itself, since sin itself is not a “thing”, an entity, but the lack of something. Paul tells us this same thing, in one of his letters
7 What, then, shall we say? Is the Torah sin? Let it not be! However, I did not know sin except through the Torah. For also the covetousness I knew not if the Torah had not said, “You shall not covet.”
8 But sin, having taken the occasion through the command, did work in me all sorts of covetousness. For apart from Torah sin is dead.
9 And I was alive apart from the Torah once, but when the command came, the sin revived, and I died.
10 And the command which was to result in life, this I found to result in death.
11 For sin, having taken the occasion through the command, deceived me, and through it killed me.
12 So that the Torah truly is set-apart, and the command set-apart, and righteous, and good.
What Paul is saying here, is that, when there was no law, there was no sin (Rom 4:15). He says that, the law came to point out sin. However, the moment this happened (when the law came) sin became alive (since sin did not exist before the law) (this is what is said in verses 8, 9 and 11 above).
Now, the biggest question is, how can Lucifer sin in heaven, before the foundation of the world was laid, if the law was only given at Mount Sinai. One cannot sin where there is no law.
Well, to this question, I ask that we look at Cain and Abel. These two, a number of years after Adam and Eve left the Garden, both of them sacrificed to Elohim. Now, how did they know to sacrifice, if they did not get a command from Father, and if the law was only given at Mt Sinai? While the law was only written down at Mt Sinai, Father cannot create a new part of Himself after He already existed. The Law is a part of our Father. Its His character. It is how He chooses to reveal Himself to us. John 1:1 says that the “word” was in the beginning with Elohim, and that the word was Elohim. Therefore, the entire scriptures, is Elohim. Therefore, it must have existed from the very beginning. and that is how Lucifer could sin before the Garden of Eden.
