The physician Luke has generally been credited with writing this account. From as early as the second century C.E. there is written evidence in the Muratorian Fragment, the oldest known list of New Testament books, that this gospel is being attributed to Luke. Certain aspects of this gospel may also be viewed as pointing to a well-educated physician as its writer. The vocabulary found therein is more extensive than that of the other three gospels - Matthew, Mark, and Acts. At times the descriptions of afflictions healed by Jesus are more specific than in the other accounts. It was evident before writing the book of Acts that Luke completed his Gospel. Since he had accompanied Paul to Jerusalem at the end of the apostle’s third missionary journey, he would have been in a good position to trace accurately the things pertaining to Jesus Christ in the very land where the son of God had carried out his activity. Following Paul’s arrest at Jerusalem, and during Paul’s later imprisonment in Caesarea, Luke would have had many opportunities to interview eyewitnesses and to consult written records. So, it is reasonable to conclude that the gospel may have written at Caesarea sometimes during Paul’s confinement there for about two years (56-58 C.E.).
The scripture passage found at Luke 11:1-13 was an event wherein Jesus was with his twelve disciples. While Jesus was praying, one of his disciples approached him and asked to teach them how to pray. Jesus taught them the model prayer or the Lord’s Prayer found at Luke 11:2-4.
