OTHER FUNCTIONS OF THE BIBLE
In addition, we have some verses which tell us that the Bible has many other functions. The Bible has the wisdom which can help us to be saved (2 Tim. 3:15). It has the producing function of a seed. Through the Word of the Bible we can be reborn, regenerated (1 Pet. 1:23). After the new birth, the Word of the Bible is milk and food to us that we may be nourished to grow in the Lord (1 Pet. 2:2; Matt. 4:4). So, we must eat the Word (Jer. 15:16), that is, take the Word into us by exercising our spirit over the Word.
Also, the Bible can give us the best teaching and perfect the man of God (Rom. 15:4; 2 Tim. 3:16-17). If we belong to the Lord and desire to be perfect, we can surely receive perfection through His divine Word.
THE OLD TESTAMENT
The Bible is composed of two Testaments, the Old and the New. The Old Testament is mainly a prediction of Christ, predicting the coming Christ in plain words, shadows, types, and many figures.
The Lord Jesus in Luke 24 twice tells us that the Old Testament was written concerning Him (vv. 27, 44). The Old Testament can be subdivided into three main sections: Moses (which means the law), the prophets, and the psalms. The Lord said that in every section of the Old Testament there is something written concerning Him. In John 5:39 the Lord also says that the scriptures of the Old Testament are a testimony of Him. And in Hebrews 10:7 He said, "In the roll of the book [that is, the Old Testament] it is written concerning Me." Thus, the Old Testament is mainly a record prophesying of Christ as everything to the people of God.
Now we may begin a life-study of Genesis. The original title of this book was "In [the] Beginning." The Septuagint, the Greek translation of the Old Testament, adopted the title of Genesis which is a Latin word that means giving of birth, origin. Genesis brings birth to everything, gives the origin of everything. Genesis is a book containing all the seeds of the divine truths. All the divine truths in the whole Bible were sown in this book.
