Why does it matter how one views the covenant with Abraham? Are there actually different views on it? My experience leads me to believe that most folks don’t really think too much about such things. Yet this singular item is, in fact, the biggest wedge between Reformed Baptists and our Presbyterian brothers.
As pointed out in this book review, the matter of covenants in the Bible and how one looks at and considers them makes a huge difference in myriad other doctrines that sprout forth. To help understand this issue further, I commend this sermon by Jeffrey Johnson, on the topic of the Abrahamic Covenant.
