"Jeff Waddington, Ryan Noha, and Camden Bucey discuss different aspects of covenant union in the Bible. In this present age, covenant and election are not identical. Throughout the Bible, there have been members of the visible church who are not elect and eventually fall away. Our Lord spoke of a mixture of wheat and chaff, sheep and goats. This does not refer only to the world, but even to the covenant community (see Malachi 4). This clip is from Christ the Center episode 743 (https://www.reformedforum.org/ctc743)" from video introduction.
