Truth is basing her argument around the experiences of someone else. The Bible is a book that tells the story of life before, during, and after Christ from many points of view and experiences of the people who lived during this time. Although, you could argue that Truth has based her argument from knowledge found in a book as the Bible is book, the Bible tells the truth, just as in her name. These people really existed and experienced these situations. Therefore, Truth is basing her argument on what God, Jesus, Mary, Martha, and Lazarus experienced.
