Just want to share this with you:
Teacher: Did God create everything?
Students: Yes.
Teacher: If so, then God also created evil. Therefore, God is evil.
(A student stood up)
Student: Sir, does cold exists?
Teacher: Yes, it does.
Student: Actually Sir it does not. Based on the Laws of Physics,
cold comply the absence of heat and so does dark exist Sir?
Teacher: Of course it does.
Student: Dark doesn't exist. Dark is only the absence of light.
Just like evil, it is only the absence of God in a man's heart.
