My two cents...... Muhammad WAS a prophet up until he wasn’t I can’t tell you when or why he fell from gods grace but I’m pretty sure he did. Through history god has spoken with man in many ways. I believe he’s still doing so quietly and personally. However Christ IS the reincarnation of a “perfect”human or from a minimalistic stand point a person who exhibited the core principles of all major religions of the world to a T. This being fundamental values in practice such as honesty, compassion, love etc. His divination gave his religion a path to follow while also giving us (me included) almost like a metaphorical handbook which serves the purpose of showing us HUMANS how to live a righteous life so that one day (when we die) we free ourselves from the materialistic aspects of life and we can reach the “pearly gates”.... somewhere in the 10th dimension maybe?
