FORASMUCH as many have taken in hand to set forth in order a declaration of those things which are most surely believed among us, 2 Even as they delivered them unto us, which from the beginning were eyewitnesses, and ministers of the word; 3 It seemed good to me also, having had perfect understanding of all things from the very first, to write unto thee in order, most excellent Theophilus, 4 That thou mightest know the certainty of those things, wherein thou hast been instructed.
Luke 1:1-4.
The author of Luke addresses the letter to the "most excellent Theophilus." ----In the intro he says that he has had perfect understanding of all these things from the very first, implying that he had a front row seat to all that's expounded in the letter.
THE former treatise have I made, O Theophilus, of all that Jesus began both to do and teach, 2 Until the day in which he was taken up, after that he through the Holy Ghost had given commandments unto the apostles whom he had chosen: 3 To whom also he shewed himself alive after his passion by many infallible proofs, being seen of them forty days, and speaking of the things pertaining to the kingdom of God
Acts 1:1-3.
The "
former treatise have I made, O Theophilus" appears to be the Gospel of Luke. And in this latter treatise, Acts, we have Paul's beloved physician, Luke, recounting his journeys with his close companion Paul. In these missionary journeys, Luke and Paul encounter Peter, John, and Mark, more than once (Mark being the author of another of the Gospels). This Peter and John knew Jesus and his mother Mary very well, such that Luke and Paul had direct and intimate knowledge of persons who had direct and intimate knowledge of the Lord Jesus Christ.
The Gospel of Luke, and the Acts (written by Luke), make up almost a full third of the entire New Testament. When you realize that the Gospel of Mark is written by one of the missionaries found as a companion of Luke and Paul in the Acts, and that two other notable missionaries in this close group, John and Peter, are the writers of five other New Testament epistles, another Gospel (John's), and the book of Revelation (also written by John), it becomes perfectly apparent that this small group of missionaries are the primary source not only for the Gospels (only Matthew being exempted from this close cadre), but that something like ninety percent of the entire New Testament is written by a close cadre of men at least two of whom journeyed, ate, slept, and spoke with Jesus, Mary, Martha, and the other disciples of the Lord. Peter and John saw and spoke with the risen Lord, and then spoke directly, forcefully, and frequently, with Paul, Luke, and Mark.
Whenever anyone reads the Gospels, Acts, or the New Testament in general, they're being transported through a literary vehicle into the very center of the inner sanctum of men who both knew, loved, and were mostly martyred for, their love of God.
John
