Luke’s Gospel is the longest book in the New Testament. Being a detailed historian who researched everything, Luke tells Jesus’ story in extensive detail, more than any other Gospel. The purpose of John’s Gospel is most profoundly stated in John 20:30-31. This book is meant to awaken faith in unbelievers and to sustain the faith of those who already do believe, calling on all men to focus their eyes on the portrait of Jesus Christ and His saving work
