In the case of Lucifer, the possibility of evil and rebellion.
God did not create evil or a devil.
He created a perfect being called Lucifer who was created with a free will.
Lucifer chose to reject God’s love and in so doing became the devil.
So who is responsible for evil? Not God. The devil is.
The pain in our world today is not a result of God being absent, but a result of the devil being present.
We also have freedom of choice.
As a result, we also play a part in evil.
The pain of evil often comes from either our choices or the decisions of others.
In fact sin comes as a package.
The initial experience is exciting.
The total experience is painful.
