https://www.livescience.com/christianity-denominations.html There are more than 45,000 Christian denominations globally. Why hasn't God informed Christians as to what the "true faith" is ? This is evidence that humans created God & religions. If these people are getting "revelations" from the same God, there would be uniformity in religion.
The "true faith" is following, obeying, and attempting to be like Christ. People try this in different ways. Often they fail.
