Evil and Suffering

Evil and Suffering In this essay I will discuss the issues of evil and suffering, speak about their origins and try to prove that they have serious reasons for existing. In my opinion people sometimes misunderstand their nature, so I will also try to familiarize you with my understanding of that issue.Before we start analyzing the issues of suffering and evil let us answer several questions. What is evil? Can it be understood? Can it be forgiven? What are the differences between good and evil? Bible teaches not to do any harm neither to self, nor to others, not to commit any evil deeds. So we can say that evil is all those things, which God doesn't want to happen, but which are happening, so in that sense evil is very close to sin, and God hates sin, therefore he hates evil. But why then he allows evil happen? Let put this question off for a while and answer another one.God the Father 16Do we know what is suffering? Is that punishment for our sins? No. "Suffering is permanent, obscure and dark, and sha res the nature of infinity" William Wordsworth wrote. Let me underline this phrase "shares the nature of infinity". God is infinity and infinity is God. Thus, suffering comes not from God, but from something that shares his nature. Lucifer. Evil. When we are ill body temperature is rising, we are feeling weakness and pain, immunity tries to fight illness and illness fights back. Sin is a sort of illness; it overfills our environment and tries to corrupt us. But a part of God, the Holy Spirit in our bodies fights it and evil strikes back. That's why Jewish people were suffering, that's why thousands of believers were suffering and that's why Jesus was suffering."They spit on him, and took the...

The Age of the Ocean Floor

The Age of the Ocean Floor The youngest crust of the ocean floor can be found near the seafloor spreading centers or mid-ocean ridges. As the plates split apart, magma rises from below the Earths surface to fill in the empty void. The magma hardens and crystallizes as it latches onto the moving plate and continues to cool over millions of years as it moves farther away from the divergent boundary. Like any rock, the plates of basaltic composition become less thick and denser as they cool. When an old, cold and dense oceanic plate comes into contact with a thick, buoyant continental crust or younger (and thus warmer and thicker) oceanic crust, it will always subduct.  In essence, oceanic plates are more susceptible to subduction as they get older.   Because of this correlation between age and subduction potential, very little ocean floor is older than 125 million years and almost none of it is older than 200 million years. Therefore, seafloor dating isnt that useful for studying plate motions beyond the Cretaceous. For that, geologists date and study continental crust.  Ã‚   The lone outlier (the bright splash of purple that you see north of Africa) to all of this is the Mediterranean Sea. It is the lasting remnant of an ancient ocean, the Tethys, that is shrinking as Africa and Europe collide in the Alpide  orogeny. At 280 million years, it still pales in comparison to the four-billion-year-old rock that can be found on the continental crust.   A History of Ocean Floor Mapping and Dating The ocean floor is a mysterious place that marine geologists and oceanographers have struggled to fully grasp. In fact, scientists have mapped more of the surface of the Moon, Mars, and Venus than the surface of our ocean. (You may have heard this fact before, and while true, there is a logical explanation as to why.)   Seafloor mapping, in its earliest, most primitive form, consisted of lowering weighted lines and measuring how far the sunk. This was done mostly to determine near-shore hazards for navigation. The development of sonar in the early 20th century allowed scientists to get a clearer picture of seafloor topography.  It didnt provide dates or chemical analyses of the ocean floor, but it did uncover long oceanic ridges, steep canyons and many other landforms that are indicators of plate tectonics.   The seafloor was mapped by shipborne magnetometers in the 1950s and produced puzzling results - sequential zones of normal and reverse magnetic polarity  spreading out from the oceanic ridges. Later theories showed that  this was due to the reversing nature of Earths magnetic field. Every so often (it has occurred over 170 times over the past 100 million years), the poles will suddenly switch.  As the magma and lava cool at seafloor spreading centers, whatever magnetic field is present get ingrained into the rock. The ocean plates spread and grow in opposite directions, so rocks that are equidistance from the center have the same magnetic polarity and age. That is, until they get subducted and recycled under less-dense oceanic or continental crust.   Deep ocean drilling and radiometric dating in the late 1960s gave an accurate stratigraphy and precise date of the ocean floor. From studying the oxygen isotopes of the shells of microfossils in these cores, scientists were able to begin studying the Earths past climates in a study known as paleoclimatology.
