In the first session (45 min. video) he spoke about God-given authority in the Christian home. God has given (1) an instruction to obey, (2) delegation to carry out his will, and (3) his purpose for rearing children.
During the second session, he pointed out four tools God has put in place for the training of children: (1) parents, (2) the Bible, (3) the local church, and (4) the rod. Unfortunately, the camera ran out of batteries during the second session. So, you’ll have to take my word for it that what was shared was very helpful.
