Islam is true religion?

to answer this question i will tell you about the starting of christanity that once the pope told about earth being the centre of universe but this was later corrected by people , here is a false belief in christanity religion .Islam told that all other holy books execpt quarn were re written and also there were and are wrong beliefs in christanity which people just follow and are destroyed by the pleasures.all people are doing things which all messengers tried to stop but are pratised again in christans mainly.CHrisanity says all these things are right but beleve me,gambling,drinking,kissing are making allah more angrier.Once when i was not a true beliver of islam i always got humilated and got horrible percentages in class. but then i begin studing islam to find false beliefs like earth being flat etc in chrisanity which was later corrected but none were in islam ,all teachings were correct and showed me how to become allahs beliver . christan eat things which are banned in islam , later get diseases and spend lot of money to be healthy which shows that pope changed christan book to have pleasures.AFter beliving islam faith i become power ful both mentally and phiscally and even got the word allah in arbai on my left hand made of the position of veins . This is true , there are people like me who have being granted this gift from allah all mighty him self.One more thing that chrisanity has said about allah having a family tree, this is surely wrong as allah has no family as he is the only one and there is no one likehim, even if this was true,do you really that man kind would be alive .hazrat isa [ala islam] was a messenger of allah like hazrat muhamad[S.a.w.w] .Allah created 4 religions in which islam and chrisanity are top now,to see that man kind would follow pleasuers in chrisanity with open belief to gamble ,drink etc[which laterly make peoplr ill] or follow islam to with draw from these acts and follow the religion to earn allahs mercy. I have tried to see mistakes in islam but none were present and every thing was perfetly explained that there was nothing to questions about as there is nothing which would harm muslims either mentally or phisacally.when i learned about the faith of islam i become strong and the most smartest in my school[class] and the mark of allah on my hand was amazing.but one thing i learned that if i lose faith in my mission allah would send his wrath upon me but that was long ago and i under stand islam completly.islam is the true religion and all you will understand if you under stand quarn completely.allah offers heaven to true muslims but i am not so much intrested as i only want allah mercy etc not pleasure.chrisanity is weakining and today many people are adopting islam.all of this is not a lie,every thing in here is true and all of you will under stand only if you under stand islam.
