Practically all scholars believe that Luke wrote his Gospel before he wrote Acts. Many conservative scholars hold that he wrote Acts during Paul's first Roman imprisonment during which the book ends (60-62 A.D.). Luke accompanied Paul during much of that apostle's missionary ministry. At times Luke was not with Paul, but he was ministering as Paul's representative in one or another of the churches that Paul had founded. Evidently Paul was Luke's primary source of information for his Gospel and Acts as Peter was Mark's primary source for the second Gospel. Luke may have written his Gospel during Paul's first imprisonment in Rome along with Acts. However, it seems more likely in view of how Luke introduced these two books that he wrote the Gospel sometime earlier than Acts. Luke had the most time to write this Gospel during Paul's Caesarean imprisonment (57-59 A.D., cf. Acts 24:1-26:32). This seems to me to be the most probable date of writing.17
