Genesis means 'origin', a very appropriate name for a book that reveals the origins of all human history. Naturally the book is full of firsts - we are going to highlight the major firsts of this book.
Genesis must be understood to be the first of a larger work known as the Pentateuch - or the first five books of the Bible, which has been traditionally held to be written by Moses.
(Exodus 17:14; Exodus 24:4-7; Numbers 33:2; Deuteronomy 31:9. ) As the Pentateuch was originally one
book with five sections, to prove authorship of one is to do so of all.
By Moses the whole of the Pentateuch was called 'the book of the Covenant,' (Exodus 24:7 ); 'the book of the Law,' (Deuteronomy 28:58, Deuteronomy 31:24-26 ); and 'this book of the law', (Deuteronomy 30:10 ).
If you too would live by the Word, you will succeed and prosper. That may not be according to the world's standards - but you will be successful in God's eyes, not only for time but for eternity.
