I know someone who routinely lies. But he does it so well, I keep thinking that this time it’s the truth. Alas! Not so.
Our enemy is a liar (the Bible tells me so):
John 8:44 (NLT)
He has always hated the truth, because there is no truth in him. When he lies, it is consistent with his character; for he is a liar and the father of lies.
