So in the mind of St. Luke the thought ripens into a purpose. Since others "have taken in hand" to draw up a narrative concerning those matters which have been "fulfilled among us," he himself will do the same; for has he not a special fitness for the task, and peculiar advantages? He has long been intimately associated with those who from the very first were "eye-witnesses and ministers of the Word," the chosen companion of one Apostle, and doubtless, owing to his visit to Jerusalem and to his prolonged residence at Cæsarea, personally acquainted with the rest. His shall not be a Gospel of surmise or of rumour; it shall only contain the record of facts--facts which he himself has investigated, and for the truth of which he gives his guarantee. The clause "having traced the course of all things accurately from the first"--which is a more exact rendering than that of the Authorized Version, "having had perfect understanding of all things from the very first"--shows us the keen, searching eye of the physician. He looks into things. He distinguishes between the To seem and the To be, the actual and the apparent. He takes nothing for granted, but proves all things. He investigates his facts before he endorses them, sounding them, as it were, and reading not only their outer voice, which may be assumed, and so untrue, but with his stethoscope of patient research listening for the unconscious voices that speak within, and so finding out the reality. He himself is committed to nothing. He is not anxious to make up a story. Himself a searcher after truth, his one concern is to know, and then to tell, the truth, naturally, simply, with no fictitious adornment or dressing up of his own. And having submitted the facts of the Divine Life to a close scrutiny, and satisfied himself of their absolute truth, and having thrown aside the many guesses and fables which somehow have woven themselves around the wonderful Name, he will write down, in historical order as far as may be, the story, so that his friend Theophilus may know the "certainty of the things" in which he has been "instructed," or orally catechized, as the word would mean.
