[Sidenote: _Effort in Bible Study_] The Bible contains all the principles that men need to understand in order to be fitted either for this life or for the life to come. And these principles may be understood by all. No one with a spirit to appreciate its teaching can read a single passage from the Bible without gaining from it some helpful thought. But the most valuable teaching of the Bible is not to be gained by occasional or disconnected study. Its great system of truth is not so presented as to be discerned by the hasty or careless reader. Many of its treasures lie far beneath the surface, and can be obtained only by diligent research and continuous effort. The truths that go to make up the great whole must be searched out and gathered up, “here a little, and there a little.”[149] [Sidenote: _A Perfect Whole_] When thus searched out and brought together, they will be found to be perfectly fitted to one another. Each Gospel is a supplement to the others, every prophecy an explanation of another, every truth a development of some other truth. The types of the Jewish economy are made plain by the gospel. Every principle in the word of God has its place, every fact its bearing. And the complete structure, in design and execution, bears testimony to its Author. Such a structure no mind but that of the Infinite could conceive or fashion. [Sidenote: _Intellectual Discipline_] In searching out the various parts and studying their relationship, the highest faculties of the human mind are called into intense activity. No one can engage in such study without developing mental power. And not alone in searching out truth and bringing it together does the mental value of Bible study consist. It consists also in the effort required to grasp the themes presented. The mind occupied with commonplace matters only, becomes dwarfed and enfeebled. If never tasked to comprehend grand and far-reaching truths, it after a time loses the power of growth. As a safeguard against this degeneracy, and a stimulus to development, nothing else can equal the study of God’s word. As a means of intellectual training, the Bible is more effective than any other book, or all other books combined. The greatness of its themes, the dignified simplicity of its utterances, the beauty of its imagery, quicken and uplift the thoughts as nothing else can. No other study can impart such mental power as does the effort to grasp the stupendous truths of revelation. The mind thus brought in contact with the thoughts of the Infinite can not but expand and strengthen. [Sidenote: _Spiritual Development_]
