Sermon: Amos: God's Just Judgment of Unjust People. Listen to this week's sermon as we continue our series on The Minor Prophets. The book of Amos has been quoted frequently in American politics and been used as a manifesto of "social justice." But is that what this prophet is all about? Pastor Robb goes through the book of Amos in this sermon, focusing especially on Amos 8, to show how this book speaks not to social justice, but to a higher level of justice, the kind of justice we really need, and the kind of justice that required a perfect sacrifice.
