A religion is not limitating. Christ did works. Thats part of religion. You evangalize. Thats religion. Prayer is just as much as worship. Without religion, where is god?
Multiple religions exist because people evolve from different countries, cultures, and languages. Each religious group and community make sense of life in their given ways of relating to self, others, and their environment. Its an evolution of culture. Its not mysterious. Its very well studied in athropology, psychology, sociology, theology, archrology, metaphysics, and more. When you study these things you realise everyone has separate truths. They are not under one religion. There is no "god knows" when studying different worldviews outside your own.
Instead, challenge the issue. How would many religions fall under one truth? I asked
@loverofhumanity ,
@adrian009 , and
@arthra this but bahaullah was somewhere involved.
Describe truth without god, christ, prophets, and no saying "we dont know" because why believe in anything if you dont know its true. Speculate.
