20:6.2
On a mortal-bestowal mission a Paradise Son is always born of woman and grows up as a male child of the realm, as Jesus did on Urantia. These Sons of supreme service all pass from infancy through youth to manhood just as does a human being. In every respect they become like the mortals of the race into which they are born. They make petitions to the Father as do the children of the realms in which they serve. From a material viewpoint, these human-divine Sons live ordinary lives with just one exception: They do not beget offspring on the worlds of their sojourn; that is a universal restriction imposed on all orders of the Paradise bestowal Sons.
