When reading a passage in the Bible, allow Scripture to answer your questions. When reading the book of Luke, his writing answers many questions about him. In Luke 1:1-4, we are told that he is a Historian writing the account regarding Jesus for Theophilus.
As a rule of thumb, it is a good idea to read the complete book of the New Testament in one sitting. The letters written by Paul were meant to be read in a single sitting. The letters may seem lengthy, but the entertainment was different for those times.
