The background of the new covenant is forged in the writings of the prophets.  And yet, the prophets can be some of the hardest material in Scripture to understand.  Along with the Lesson on the New Covenant (Part 1) itself, these two resources serve to clarify your understanding of the prophets.  The first resource helps to unpack Isaiah by giving a detailed outline of each chapter; while the second is a study through the concepts of Ezekiel 36 based on Thomas Guthrie's book, "The Gospel in Ezekiel".  I hope you enjoy these and that they prove to be a blessing to you.
