Greenleaf then argues that the gospel writers can be shown to be honest in their character and do not show any motives to falsify their testimony (pp. 28–31). He claims that keen observations and meticulous details are related by Matthew and Luke, and he concludes this demonstrates their ability (pp. 31–32). Greenleaf notes that there are parallel accounts from the evangelists concerning the central events of Jesus' life and that these accounts are not verbally identical. He maintains that discrepancies in their accounts are evidence that the writers are not guilty of collusion, and that the discrepancies in their respective accounts can be resolved or harmonized upon careful cross-examination and comparison of the details (pp 32–35). Greenleaf argues against the scepticism of the Scottish empirical philosopher David Hume concerning reports of miracles. He finds fault with Hume's position about "immutable laws from the uniform course of human experience" (p. 36), and goes on to assert that it is a fallacy because "it excludes all knowledge derived by inference or deduction from facts, confining us to what we derive from experience alone" (pp. 37–38). Greenleaf takes as his own assumption that as God exists then such a being is capable of performing miracles. He then argues that the various miracles reported in Jesus' ministry occurred in open or public contexts where friend and foe alike were witnesses (pp 39–42). Lastly, Greenleaf examines the problem of uniform testimony among false and genuine witnesses, and finds there is sufficient circumstantial evidence to support the accounts of the Four Evangelists.
