The origin of sin has been debated for centuries.
Some believe sin began when Adam and Eve disobeyed God and ate the
forbidden fruit. But it is necessary to go back even further before
the creation of humanity to the time when Lucifer was created. He
was beautiful cherub that led the other angels in praise of God.
There was no evil initially present, but the goodness in him was
replaced with discontent, which led to anger and hate towards God,
and Lucifer chose to make himself into an evil entity. The other
angels that opted to join his rebellion also became spiritually
corrupted. People often blame God for creating evil or allowing
it to exist but that is not the case at all. Being evil is a
personal choice that everyone must make and God cannot be blamed for
your decisions. If God did not snuff out the Devil, why would He
behave differently with mankind? Following the expulsion from the
Garden of Eden, Cain became so angry that he killed his brother and
the rest is history. So the next time this topic comes up, remember
that Lucifer was the original sinner.
