I have heard that this story has been going on for some time (Albert Einstein spoke it from what most sources say) although from other sources it has not been accredited to any certain person, but even so I still have found it very interesting and I am only posting it because I find it interesting.
"A University professor at a well known institution of higher learning challenged his students with this question.
Did God create everything that exists?
A student bravely replied, "...Yes he did!" "God created everything?" The professor asked. "Yes sir, he certainly did," the student replied. The professor answered, "If God created everything; then God created evil. And, since evil exists, and according to the principle that our works define who we are, then we can assume God is evil."
The student became quiet and did not answer the professor's hypothetical definition. The professor, quite pleased with himself, boasted to the students that he had proven once more that the Christian faith was a myth. ---
Another student raised his hand and said, "Can I ask you a question professor?" "Of course", replied the professor. The student stood up and asked, "Professor, does cold exist?" "What kind of question is this? Of course it exists. Have you never been cold?" The students snickered at the young man's question. The young man replied, "In fact sir, cold does not exist. According to the laws of physics, what we consider cold is in reality the absence of heat. Everybody and every object is susceptible to study when it has or transmits energy, and heat is what makes a body or matter have or transmit energy. Absolute zero (- 460 degrees F) is the total absence of heat; all matter becomes inert and incapable of reaction at that temperature. Cold does not exist. We have created this word to describe how we feel if we have too little heat. The student continued. "Professor, does darkness exist?" The professor responded, "Of course it does". The student replied, "Once again you are wrong sir, darkness does not exist either. Darkness is in reality the absence of light. Light we can study, but not darkness. In fact we can use Newton's prism to break white light into many colors and study the various wavelengths of each color. You cannot measure darkness. A simple ray of light can break into a world of darkness and illuminate it. How can you know how dark a certain space is? You measure the amount of light present. Isn't this correct? Darkness is a term used by man to describe what happens when there is no light present."
Finally the young man asked the professor. "Sir, does evil exist?" Now uncertain, the professor responded, "Of course as I have already said. We see it every day. It is in the daily example of man's inhumanity to man. It is in the multitude of crime and violence everywhere in the world. "These manifestations are nothing else but evil."
To this the student replied, "Evil does not exist sir, or at least it does not exist unto itself. Evil is simply the absence of God. It is just like darkness and cold, a word that man has created to describe the absence of God. God did not create evil. Evil is not like faith, or love, that exist just as does light and heat. Evil is the result of what happens when man does not have God's love present in his heart. It's like the cold that comes when there is no heat or the darkness that comes when there is no light." "
I have noticed that often evil is depicted as darkness in the scriptures, and God as Light. Anything relating to what is true and right in scriptures is attributed to being Light, whereas anything wrong and evil is shown to be darkness.
It says in scriptures "And this is the condemnation, that light is come into the world, and men loved darkness rather than light, because their deeds were evil." ~John 3:19
I think that darkness in the sense of sin is an absence of God's Light, if God ever ceased caring for man, we would indeed cease living, because God is the Creator of life, and He is the one who sustains all. "For in him we live, and move, and have our being; as certain also of your own poets have said, For we are also his offspring." (Acts 17:28) Evil exists in that it exists in those who are wicked, who have forsaken God's Light, and it does not shine in their lives or hearts. Evil is not from God, evil is what happens when we wander from Him out of Light and dwell in darkness. “To the law and to the testimony: if they speak not according to this word, it is because there is no light in them. “ Isaiah 8:20
“I form the light, and create darkness: I make peace, and create evil: I the Lord do all these things.” Here it says He creates all things, everything is in His power. Isaiah 45:7
Now I would also like to say, everything that God does is Just and Right, but we as humans are only deserving of punishment for our sins and wrongdoings. To think that we have rights, when we have all fallen short of God's Light and Holiness, is in a way to place ourselves above our Creator, since He is pure, and we sinful without Him. We would not be able to see at all but blindly dwell in darkness if God did not shed His Mercy and Light into our lives and draw us unto Himself. God is perfectly Just in destroying what is not of His Light, this is not evil as in sin is, this is Justice. We were created to glorify our Creator, and anyone who has turned away from Light is not in the Light. Anyone who has ever been selfish or sinned in any way, anything without the Light of Life in their hearts is deserving of punishment. Punishment is not evil in the sense that sin is, nor is it wrong, it is only what is Just and Right, what one who has rejected the True Light is deserving of. Sinners are only deserving of evil befalling them and to stumble in darkness. God can and does allow this darkness and evil to befall sinners; not because He does wrong, but because He is indeed Just, Holy and Pure.
I know this post is long, so thank you to anyone who takes the time to read through it. For some reason my computer hasn't been wanting to post this each time I try, and so hopefully it works.
