The topic of this post is part 2 of chapter 12 from Archibald Alexander’s book: Practical Sermons to be read in Families and Social Meetings. His topic derives from, Jermiah 17:9 The heart is deceitful above all things, and desperately wicked: who can know it? I think is it important to understand this foundational biblical concept from Jeremiah’s writings because it is how the whole of scripture speaks of mankind. But you may not realize that if you attend a mainline Christian church, unless, of course, you are a student of the Bible.
