"And [Jesus] said to them [Mary and Joseph], 'Why did you seek Me? Did you not know that I must be about My Father's business?' "
We ought to be easy to find on Sunday. Anyone looking for us should be able to immediately discern that we would be in our Father's house, being about His "business." Nothing trumps this, in the life of a sincere believer. Mary and Joseph apparently looked all over the place for the young Messiah--but, had they immediately gone to the temple, they would have found Him.
May we be just like our Savior, in this particular (at least): that we put God's house and His business before everything else. We are sinners; Christ is holy--but in this one regard we may match Him almost step-by-step.
[Puritan quote of the day: "Do you think that when Christ is so highly advanced, and has all power in heaven and earth in His hand, He will not take care of His elect, and turn the most astonishing providences to the good of His church?" --Thomas Watson, in "A Body of Divinity"]
