DOES GOD EXISTS?
During a lesson, a university professor launch a challenge to its pupils with the following question: “Did God created everything exists? “A pupil answered with courage: ” Yes, It created all… ““Really, did God created all which exists?” he asked again. Yes, the young person answered. The professor answered: “If God has created all which exists, God has made also the evil, since the evil exists! And if we establish that our actions are a reflection of ourselves, them God is bad” The young person shout up in front of the answer of the master, proud to have demonstrated, still one more time, than faith was a myth.
Another student raised the hand and said: “can I make a question, professor?” “of course”, it was the answer of the professor. The young person raised and said: ” professor, does the cold exists?” “But! Which question is this? … Logical that exists, or maybe you have not never felt cold” The boy answered: “In reality, gentleman, the cold does not exist. According to the laws of the Physical, what we consider cold, in reality it is the absence of heat. Every body or object can be studied when it possesses or it transmits energy; the heat  allows the body to withhold or to transmit energy. Absolute zero is the total absence of heat; all the bodies remain inert, incapable to react, but the cold does not exist. We have created this definition in order to describe as we feel when we do not have heat. Now the student continued “does the dark exist? ”,. The professor answered: “yes, it exists”. The boy answered: “The dark does not exist. The dark, in reality, is the absence of light. We can study the light, not the dark! Through the prism of Nichols, the white light can be decomposed in several colors, with their different wavelengths. The dark, cannot! … How can we know the degree of dark in a determined space? Based on the presence of some amount of light in that space. The dark is a definition used from the man in order to describe the degree of darkness when there is no light”. In order to conclude, the young person inquires the professor: “Does the evil exists?” And the university professor answered: “As I have asserted at the beginning, we see crimes, violence all over the world. Those things come from the evil” the student answered: “The evil does not exist, professor, or maybe it does not exist by itself. The evil is simply the absence of goodness…the evil is a definition that the man has invented in order to describe the absence of God. God did not create the evil…The evil is the result of the absence of God in the heart of the human beings. The same happens with the cold, when there is no heat, or with the dark, when there is no light “. Everyone stand up to applaud the young person and the master, shaking his head, remained silent. The chancellor of the University, that it was present, walked towards the young student and he asked him: “What is your name” The answer was: “My name is Albert Einstein”.
God is a truth " not tangibile" but He lives in our hearts. Let`s learn to listen to him.
