The first five books of the Bible were written by Moses and are called the Torah. God made a promise to Abraham to increase his descendents and make them into a great nation, and that through his line all people on earth would be blessed. God was promising to send the Messiah, the Savior of the world through that nation. Abraham, Isaac, Jacob, and Joseph are the first four generations of the nation of Israel. The foundations of all creation, and of the story of salvation are found in these stories. And God is still at work in the same ways in our world today!
