while it is correct to say God created Satan, it’s never correct to say that God created the sin within Satan. Satan chose his own way
Isaiah 14:12-14
“How you are fallen from heaven,
O Day Star, son of Dawn!
How you are cut down to the ground,
you who laid the nations low!
You said in your heart,
I will ascend to heaven;
above the stars of God
I will set my throne on high;
I will sit on the mount of assembly
in the far reaches of the north;
I will ascend above the heights of the clouds;
I will make myself like the Most High.’
God never causes sin
James 1:13
Let no one say when he is tempted, “I am being tempted by God,” for God cannot be tempted with evil, and he himself tempts no one.
Did God give free will to the Angels?
To me is seems so, otherwise Lucifer would not have chosen the path he did.
God did not create Satan with sin in him
Ezekiel 28:17
‘Your heart was lifted up because of your beauty;
You corrupted your wisdom for the sake of your splendor;
I cast you to the ground,
I laid you before kings,
That they might gaze at you.
The same is for us, we have free will to choose what we want to do.
Do we gaze at ourselves or do we gaze at our creator.
Truth is this side of eternity we will not fully understand what it is all about with satan and God.
Isaiah 55:8-9
“For My thoughts are not your thoughts,
Nor are your ways My ways,” says the Lord.
“For as the heavens are higher than the earth,
So are My ways higher than your ways,
And My thoughts than your thoughts.
One thing that is for sure
Revelation 20:10
Then the devil, who had deceived them, was thrown into the fiery lake of burning sulfur, joining the beast and the false prophet. There they will be tormented day and night forever.
