A deathbed conversion is the adoption of a particular religious faith shortly before dying. A religion is a set of Tenets and practices often centered upon specific Supernatural and moral claims about Reality, the Cosmos Faith is a Belief in the trustworthiness of an Idea. Formal usage of the word "faith" is usually reserved for concepts of Religion, as in Making a conversion on one's deathbed may reflect an immediate change of belief, a desire to formalize longer-term beliefs, or to complete a process of conversion already underway. Religious conversion is the adoption of a new religious identity or a change from one religious identity to another A deathbed is a Bed in which a person dies or the last hours before a death Many believe that the imminence of death concentrates the mind, and propels a desire for people to put their lives aright in preparation for what they consider to await them after death.
Deathbed conversions have been most prominent within Christianity. Christianity ( Greek Χριστιανισμός from the word Xριστός ( Christ)is a monotheistic Religion centered on the life and teachings Indeed, a deathbed conversion appears in the Gospel of Luke with the confession of the good thief who is crucified alongside Jesus. The Gospel of Luke (Gk Κατά Λουκάν Ευαγγέλιον) is a synoptic Gospel, and is the third and longest of the four canonical Gospels of the Jesus of Nazareth (7–2 BC / BCE —26–36 AD / CE) (Luke 23:39-43) Jesus accepts his conversion, saying “Today you shall be with Me in Paradise". 
Perhaps the most momentous conversion in Western history is that of Constantine I, Roman Empire. Flavius Valerius Aurelius Constantinus (27 February ca. 272 &ndash 22 May 337 commonly known as Constantine I, Constantine the Great, or Saint Constantine The Roman Emperor was the ruler of the Roman State during the imperial period (starting at about 27 BC He was baptised only shortly before his death in 337. In Christianity, baptism ( Greek, "immersing" "performing Ablutions " is the ritual act with the use of water by which one is admitted Events By Place Roman Empire September 9 — Constantine II, Constantius II, and Constans succeed their He originally converted (unofficially) at a certain battle after having a dream in which God spoke to him. Then He had crossed painted on his warriors shield.
Many religious leaders disapprove of deathbed conversion, considering it based on fear rather than true belief. Many deathbed converts lived in violation of the tenets of the religion to which they wish to convert. Many consider this a form of "hedging one's bets," similar to Pascal's Wager. Pascal's Wager (or Pascal's Gambit) is a suggestion posed by the French Philosopher Blaise Pascal that even though the Existence of God
The deathbed conversion has also been a target of humor. Voltaire, on his own deathbed, was asked by a priest to renounce Satan. François-Marie Arouet ( 21 November 1694 30 May 1778) better known by the Pen name Voltaire, was a French Voltaire replied, "This is no time to be making new enemies. " Those turned out to be his last words. 
Religious believers throughout history have often claimed famous or respected non-believers (or believers in other religions) have undergone deathbed conversions to their own religion.
One famous example is Charles Darwin in the Lady Hope urban legend, in which it was claimed Darwin said: "How I wish I had not expressed my theory of evolution as I have done. Charles Robert Darwin (February 12 1809 &ndash April 19 1882 was an English naturalist, who realised and demonstrated that all Species of life Elizabeth Reid Lady Hope ( née Cotton December 9 1842 &ndash 8 March 1922) was a British evangelist who is generally believed " He went on to say that he would like her to gather a congregation since he "would like to speak to them of Christ Jesus and His salvation, being in a state where he was eagerly savoring the heavenly anticipation of bliss. "  Lady Hope's story was printed in the Boston Watchman Examiner. The story spread, and the claims were republished as late as October 1955 in the Reformation Review and in the Monthly Record of the Free Church of Scotland in February 1957.
From Darwin's son: "Lady Hope's account of my father's views on religion is quite untrue. I have publicly accused her of falsehood, but have not seen any reply. " 
From Darwin's daughter: "I was present at his deathbed. Lady Hope was not present during his last illness, or any illness. I believe he never even saw her, but in any case she had no influence over him in any department of thought or belief. He never recanted any of his scientific views, either then or earlier. We think the story of his conversion was fabricated in the U. S. A. The whole story has no foundation whatever. " 
Sartre's atheism was foundational for his style of existentialist philosophy. Jean-Paul Charles Aymard Sartre (21 June 1905 &ndash 15 April 1980 commonly known simply as Jean-Paul Sartre (ʒɑ̃ pol saʁtʁə was a French Atheism Existentialism is a philosophical doctrine which posits that individuals create the meaning and essence of their lives and that this essence follows from their existence In March 1980, about a month before his death, he was interviewed by his assistant, Benny Lévy, and within these interviews he expressed his interest in Judaism which was inspired by Levy's renewed interest in the faith. Benny Lévy (aka Pierre Victor) was a philosopher political activist and author Judaism (from the Greek Ioudaïsmos, derived from the Hebrew יהודה Yehudah, " Judah " in Hebrew יַהֲדוּת Yahedut Through Sartre's study of Jewish history he became particularly interested in the messianic idea of the faith. Jewish history is the History of the Jewish people, faith, and culture. Some people apparently took this to indicate a deathbed conversion; however, the text of the interviews makes it clear that he did not consider himself a Jew, and was interested in the ethical and "metaphysical character" of the Jewish religion, while continuing to reject the idea of an existing God.
