The biblical term is actually blasphemy and we all no how seriously blasphemy was dealt wit in the old and new testament.
Blasphemy is when one equates ones self with God and not giving him his due.By him all things were made and without him nothing was. We need to remember this at all times that without him we can do nothing and all that we do and achieve is cause he allows, helps us to do.
Give him his due;acknowledge him in all things and give him thanks and praise.
