"God cannot lie. For this reason alone, we know that whatever he personally has communicated to mankind is true." This is how Editor Tom Fishbeck introduced a pro-inerrancy comment in the April 1991 issue of Bible Answers Newsletters (p. 3). It was a familiar bibliolatry tactic. A Bible passage is quoted and then supported with the claim that God cannot lie. The claim is often "proven" by citing Hebrews 6:18, which says that it is impossible for God to lie, or Titus 1:2, which says that God can not lie.
Aside from the obvious circular reasoning taking place here, the tactic is flawed by contradictory statements in the Bible about a much ballyhooed aspect of God's nature. If it is truly impossible for God to lie, then bibliolaters are going to have to explain some confusing Bible passages.
