know the certainty

The Christian world is quite dependent on Luke for the Christmas narratives.  I regularly remind my students this time of year that they run the danger of missing the full scope of the Christmas story if they start at chapter 2.  Chapter 1 is where the good stuff is!
Luke tells us in the first 5 verses of his gospel why he is writing:

​Luke 1:1        Many have undertaken to compile a narrative about the events that have been fulfilled among us, 2 just as the original eyewitnesses and servants of the word handed them down to us. 3 So it also seemed good to me, since I have carefully investigated everything from the very first, to write to you in an orderly sequence, most honorable Theophilus, 4 so that you may know the certainty of the things about which you have been instructed.
We can know the certainty about the good news of Jesus, and it starts with the story of Christmas! 
​Praise God!
