The Bible is its own expositor. Scripture is to be compared with scripture. The student should learn to view the word as a whole, and to see the relation of its parts. He should gain a knowledge of its grand central theme, of God’s original purpose for the world, of the rise of the great controversy, and of the work of redemption. He should understand the nature of the two principles that are contending for supremacy, and should learn to trace their working through the records of history and prophecy, to the great consummation.
