No TRUTH is independent of any other truth; but each truth is linked to every other by invisible lines running out in all directions, and meeting and crossing the similar lines which pass between other truths. This is just as true in the sphere of the Sabbath-school teacher as in any other sphere. A teacher may have to tell of Adam, or Seth, or Methuselah; but from the truth regarding these, he can, if he wishes, follow up the connecting line to any other truth of the Bible, and even to Him who is himself the truth of the Bible. And for the same reason the teacher will find it not only possible, but profitable, to connect every lesson as he goes along with the whole series of lessons which preceded it, however dissimilar these may seem to be. There are connecting links; and they ought to be found. By so doing a teacher will discover that truths which are linked in his own mind are also linked together in the minds of his scholars, and he will be surprised at the swiftness with which their minds will leap, unprompted, from a truth which he has mentioned to one which he has in mind, and which he believed had been suggested to himself alone.
