 The roles of each deity were fluid , and each god could expand its nature to take on new characteristics . As a result , gods ' roles are difficult to <unk> or define . But despite their flexibility , the gods had limited abilities and spheres of influence . Not even the creator god could reach beyond the boundaries of the cosmos that he created , and even Isis , though she was said to be the <unk> of the gods , was not <unk> . Richard H. Wilkinson , however , argues that some texts from the late New Kingdom suggest that , as beliefs about the god Amun evolved , he was thought to approach omniscience and <unk> and to transcend the limits of the world in a way that other deities did not .
