The Operating System With Advantages and Disadvantages Nowadays, most of the computers are using the Window as their operating system.

Free Essays on Does God Exist

EXISTENCE OF GOD Does God Exist? This is one of the questions in todays society that does not have any true answer. Fortunately, there are some of us who tend to question the who’s and how’s one actually came before us. People’s opinions on the existence of God may differentiate, because of the church they attend, their parents teachings, and the religion that they believe in. In this paper I will discuss the opinions of different people including myself, a famous philosopher, and a religion who are either for or against the existence of God. In my life I myself have always came to the question does God really exist. Where then I finally came to the conclusion, that I my self would not choose one side, and instead would argue both perspectives relating to the existence of God. One of the biggest reasons why I do believe in God is because that was something that I have been taught to believe ever since I was a young child. Attending a catholic church every Sunday is what also made me help make a decision, this is because I was preached too believe in the one thing all Catholics do, and that is that a being such as God does exist. Besides having reasons that God does exist, there are also times I would have to disagree and say that he does not. This is because I feel that no actual evidence has proved that God was the one being higher then all of us. It to me also seems impossible for one person to be held responsible for creating all things on this earth. Another thing is that if God was considered such a loving, and good person then what is the explanation for young innocent children who are being abused, and the incident that happened on September 11, 2002. So therefore God should free people on this earth from any pain and suffering and he doesn’t. A question that really leaves my mind confused is that if God did exist and die then why was his body missing from the tomb. ...

Free Essays on Does God Exist God=â€Å"A being conceived as the perfect, omnipotent, omniscient originator and ruler of the universe, the principal object of faith and worship in monotheistic religions.† Only if everyone believed this. However, there are numerous reasons as to why and/or why not God’s existence can be valid. I plan to take the view of numerous authors who give endless reason as to the issue of God. But in the end I feel as if there clearly will be no justification into the matter, mainly due to the fact that I believe it difficult to prove let alone explain aspects of a mere belief. One particular author that grabbed my attention was Ramakrishna (1836-1886). Ramakrishna takes the view of God himself (assuming a male) mandating different religions to suit different aspects, different times, and even different countries. Ramakrishna speaks of ones ability to ultimately reach God if he/she follows any of the religious paths with â€Å"wholehearted devotion.† This particular statement denotes that God himself has mandated certain and particular religious paths in order to reach a religious summit. But how can such a being conceived as the perfect, enlist a path to perfection, but for those who are only as fortunate enough to achieve perfection. So if indeed God has mandated religions for particular peoples, is one religion harder to reach God as opposed to another religion? If a Jew and a Christian both were â€Å"wholehearted†, would one have an advantage or disadvantage over the other because perhaps God has chosen a better or easier religion? I believe that a â€Å"wholehearted† person needs neither particular religion nor correct path to reach God. Would a being conceived as the perfect, make it more difficult for one person to reach God rather than another? Ramakrishna also speaks of the methods in which man prays towards God. Is there a proper way to pray to a being conceived as the perfect? Perhaps ...
