1. According to the Bible, who is the Author of truth?
Ourselves
We usually always think that we are right, and the source for all truth (do you remember that as teenagers, we "knew" we were right, and everyone else was wrong?). Well, we still are wrong if we think we are the source of truth.
All scripture is given by inspiration of God, and is profitable for doctrine, for reproof, for correction, for instruction in righteousness. 2 Timothy 3:15
