If you disobey God, you are being sacrilegious:
[Merriam-Webster]
: committing or characterized by sacrilege : having or showing a lack of proper respect for a sacred person, place, or object
// sacrilegious acts
// It is difficult for religiously committed persons to acknowledge that their sacred texts are prone to sacrilegious uses.
— Mary C. Boys
Note that it goes on to mention uses of the word in non-religious contexts (but no doubt coming from that use metaphorically):
—often used in an exaggerated way in contexts unrelated to religion
// It would be sacrilegious to cut down such beautiful trees.
// Chilling your red wines may seem sacrilegious to some, and downright odd to others.
— Tess Rose Lampert
However, context would make its context clear.
Also, for sacrilege (if you prefer a noun rather than an adjective):
: gross irreverence toward a hallowed person, place, or thing
