Luke wants us to know that we might believe

Luk 1:1  Forasmuch as many have taken in hand to set forth in order a declaration of those things which are most surely believed among us, 

Luk 1:2  Even as they delivered them unto us, which from the beginning were eyewitnesses, and ministers of the word; 

Luk 1:3  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, 

Luk 1:4  That thou mightest know the certainty of those things, wherein thou hast been instructed. 

So many times we quote John and others where they say that we might know. Too often we overlook the Doctor. Dr. Luke is a writer himself, he wrote the Gospel of Luke and the Acts of the Apostles.

What sets Luke apart in his writings is his attention to detail as you would expect from a physician. He gets into details the others do not for it is up to a doctor to see what others do not.

Verse 3, he says he had a perfect understanding from the beginning and that it is time to write of it all. Now I have postulated that Luke wrote so much of the actions of the Apostles because he talked with them, he ate with them even though he was never mentioned.

I have also heard some say that he was of the 70 that Christ sent out in teams of 2 to prepare places for His arrival.

Now as to the veracity of either I do not know, I do know that Luke wrote many things and he wrote this as he stated “that thou mightiest KNOW the CERTAINTY of those things wherein you have been instructed.”

I have said this about Peter, James and John, now I will add Luke to that grouping, not only do they write but they attest with their life and in most cases their death to the truth of what they are writing.
