Luke was a Greek doctor and historian who wrote the book of Acts and one of the four Gospels. He personally witnessed many New Testament events, and interviewed people who witnessed others.
As a historian, Luke’s writings are saturated with specific and particular details, ranging from geography and cities to cultural practices and the names of local leaders. These descriptions match with reality and have been confirmed by our knowledge of the topography, archeological findings, corroborating ancient historians, and other sources.
The exhaustive weight of these details points to Luke’s testimony being as trustworthy as any other historic account.
