Luke's Purpose and Prologue

Luke 1:1-4

Since many have undertaken to set in order a narrative concerning those matters which have been fulfilled among us,

even as those who from the beginning were eyewitnesses and servants of the word delivered them to us,

it seemed good to me also, having traced the course of all things accurately from the first, to write to you in order, most excellent Theophilus;

that you might know the certainty concerning the things in which you were instructed.
