Michael had determined the time of his final bestowal on to Urantia. Michael presented himself before his brother, Immanuel so he could assign the powers of universe administration which had not previously been conferred upon Gabriel. And we also see that Immanuel is a Supreme Trinity Personality, not a Creator Son, as is Michael.

Immanuel is an important figure regarding the bestowal of Michael on our planet and even was seen as his counselor. Immanuel, in accepting the custody of the universe during the time of the Urantia bestowal, proceeded to impart the bestowal counsel which would serve as the incarnation guide for Michael when he would presently grow up on Urantia as a mortal of the realm.

I open a discussion on my answer above. What do you say?
