Why did “Luke” write his Gospel? And what purpose did he have, in depicting Jesus in the particular ways that he did, throughout this work?
The opening verses offer some clues. This book, that we know as “the Gospel of Luke”, actually describes itself, in these verses, as an “orderly account of the events that have been fulfilled among us”, written to a person named “lover of God” (in Greek, Theophilus). The book was written so that he might “know the certainty concerning the things about which you have been instructed”.
