In my understanding of LDS teaching, both Jesus and Lucifer proposed plans of salvation to Elohim, and Jesus' plan was chosen. As a result, some people on earth may attain godhood if they follow the gospel and obey its teachings to a high enough standard.
The idea that two plans of salvation were offered seems to indicate that there really was an option. So, my question is whether or not the attainment of godhood is the same for all worlds or if the requirements could be vastly different from world to world. Does each god have the option of creating his own requirements for his spiritual children to attain godhood themselves or is there, in reality, one universal gospel for all worlds and all gods?
