Genesis is the book of beginnings. Genesis shows us the beginning of many things—creation, humanity, sin, family, even nations. Genesis also shows us the beginning of worship. For example, the last verse of chapter 4 tells us, “At that time people began to call on the name of Yahweh.” (4:26) We ought to be able to learn something about worship from this book of beginnings. A recurring phrase in the book is “built an altar.” We will look at each of these texts as we examine how worship changes us or how we are “Altered by the Altar.” Over the rest of the weeks of the summer we will look at each of the texts that have this phrase. We start today in Genesis 8.
