“Luke does not seem to be portraying a dismal situation with an unfeeling innkeeper as villain. Rather, he is establishing a contrast between the proper rights of the Messiah in his own ‘town of David’ and the very ordinary and humble circumstances of his birth. Whatever the reason, even in his birth Jesus was excluded from the normal shelter others enjoyed (cf. 9:58). This is consistent with Luke’s realistic presentation of Jesus’ humanity and servanthood.”- Walter L. Leifeld, “Luke”, in The Expositor’s Bible Commentary, Volume 8: Matthew, Mark, Luke (ed. Frank E. Gaebelein; Grand Rapids, MI: Zondervan Publishing House, 1984), p. 843
Even from the beginning, Christ came to this world as a humble servant, born in lowly circumstances that he might identify with even the poorest among us.
