I Have chosen this text for the sake of one word in it, that solemn must which was so often on our Lord's lips. I have no purpose of dealing with the remainder of this clause, nor, indeed, with it at all, except as one instance of His use of the expression. But I felt it might be interesting, and might set old truths in a brighter light, if we gather together the instances in which Christ speaks of the great necessity which dominated His life, and shaped even small acts.<br><br>The expression is most frequently used in reference to the Passion and Resurrection. There are many instances in the other Gospels, in which He speaks of that must. The first of these is that of my text. Then there is another class, of which His word to His mother when a twelve-year-old child may be taken as a type, "Wist ye not that I must be about My Father's business?"
