Randall, I'm with you in my belief that God does not lie.
Lucifer is the the one who is the father of all lies.
If someone has to lie in order to protect himself, then he is exercising a lack of complete trust in the promises of God that he can deliver them in all cases. Having said that, a situation comes to mind. I think of a wartime situation in which a person from the resistance is caught and then denies any knowledge of something they are accused of. We view this in the cinema as an act of heroism because they are protecting their friends and the resistance movement. However, I can't help but think that there could be a more noble and truthful response in each instance.
