No, you do not. Many people in the world believe in and commune with God but do not follow any set religion nor religious doctrine.
No. religion is not a common problem in Sudan. The religion followed in the Sudan is Islam and as the majority of the people follow same religion and same sect, it is highly unikely that religion is a problem in Sudan. However, as Sudan is no a secular country but an Islamic state, therefore the religion plays a more important part in the life of sudanese people than in the lives of people of other countries.
People are slowly starting to turn their backs on religion and with new religions like the Jedi knight religion, religion has also lost a lot of respect and meaning. No matter what religion you are part of it will eventually "die out" so don't bother. At the rate people have been leaving religion within 100 years most people will not be part of a religion. 200 years only a very small part of the world will believe in religion and in 500 years it will be in text books (or maybe some electronic device that was invented). I myself am not part of religion but for your remaining life if you do choose to stay with your religion, converting people to your religion or persuade people to not leave will help slightly but in the log run your work will be for nothing!
Islam religion
