Luke wrote both Acts, and of course, the Gospel that bears his name. Here is what he had to say by way of introduction.
Inasmuch as many have taken in hand to set in order a narrative of those things which have been fulfilled among us, just as those who from the beginning were eyewitnesses and ministers of the word delivered them to us, it seemed good to me also, having had perfect understanding of all things from the very first, to write to you an orderly account, most excellent Theophilus, that you may know the certainty of those things in which you were instructed. (Lk. 1:1-4, NKJV)
Alternate Translation (NLT): Most honorable Theophilus: Many people have written accounts about the events that took place among us. They used as their source material the reports circulating among us from the early disciples and other eyewitnesses of what God has done in fulfillment of his promises. Having carefully investigated all of these accounts from the beginning, I have decided to write a careful summary for you, to reassure you of the truth of all you were taught.
We must be confident that all those things that are spoken of in the Bible are true. That is the starting point for any study of scripture. If any part of it can be shown to be false, then all of the Word of God is suspect. The truth is very important to you and me and it was very important to the Gospel writers. Matthew and John were Apostles and wrote about what they saw. They were right there when Jesus did His miracles and when He taught; they saw and heard it all first hand. But Mark and Luke were not there; they were not privileged to be apostles. Dr. Luke researched what he wrote and he interviewed eyewitnesses to the events that he recorded. Some of the apostles were still alive, and there were many still living that had witnessed the miracles and heard Jesus speak, so Luke talked to them, as any good reporter would do. But even more than that, what he wrote and what the authors of the other 65 books of the Bible wrote, was written by the inspiration of the Holy Spirit. Every word is truth; it is the Word of God.
How can I know that the Bible (and for our purposes the gospels), is true, you ask. You can do three things:
1. Test it to see if its promises are fulfilled in your life.
2. Verify that there is agreement between the Gospel writers.
3. It has stood the test of time and the scrutiny of men.
The revelations of God stopped prior to the coming of Christ. Heaven had been silent for more than 400 years, when the angel Gabriel made the announcement of the birth of John the Baptist. The Gospel of Jesus Christ begins with this message: “?Then an angel of the Lord appeared to him, standing on the right side of ??the altar of incense. ?And when Zacharias saw him, ??he was troubled, and fear fell upon him. But the angel said to him, “Do not be afraid, Zacharias, for your prayer is heard; and your wife Elizabeth will bear you a son, and you shall call his name John. ?And you will have joy and gladness, and many will rejoice at his birth. ?For he will be great in the sight of the Lord, and ?shall drink neither wine nor strong drink. He will also be filled with the Holy Spirit, ??even from his mother’s womb. ?And he will turn many of the children of Israel to the Lord their God. ?He will also go before Him in the spirit and power of Elijah, ‘?to turn the hearts of the fathers to the children,?’ and the disobedient to the wisdom of the just, to make ready a people prepared for the Lord” (Lk. 1:13-17, NKJV).
