Is there any record in the bible of anyone calling God a liar? if so, what was the significance? I have a "Christian" friend that basically said God is a liar. he said he is a Christian yet does not believe the bible. can you be a heaven bound Christian while telling God that what He wrote in His bible, is not true? He believes most of the bible but goes to a church where they deny much of the bible, thus he thinks much of the bible is not true.
