How did God the father who was mortal,went from mortal man to immortal man???? When God the father was a mortal man,was there anybody else there too??? any other mortal men???Before God the father created the earth-immortal body,where did he live as a mortal man??? another solar system??? or planet??? Non-LDS believe God was always immortal male who is a spirit-god head of the trinity-never a mortal man as us.We as a mortal man or human are imperfect-weakness-sin,Even Paul,Peter,and Moses,others,are not perfect.Peter deny Jesus three times.
