An automobile may exist without a dent; but where is the dent without the auto? Likewise, evil has no foundation of its own.
Consider the foundations of each..
o True ~ False
o Reality ~ Illusion
o Conceive ~ Misconceive
o Perfection ~ Imperfection
When the truth is known, falseness can no longer persuade the mind.
The light shines in the darkness, and the darkness has not overcome it. John 1:5
