Tonight we continue a supplemental study on the Sixth Petition of the Lord's Prayer with the Puritan John Whitlock's sermons through Psalm 18-23 in the book, -The Great Duty of Keeping Ourselves from Iniquity,- recently reprinted by Dr. Don Kistler -of our own RPCGA- and his Northampton Press. We now finish studying the sixth chapter, -The Application of the Doctrine,- with self -examination- and self -exhortation- and final 5-10 signs to search and single out special sins in order to sever them in sanctification- 5- a deliberate unwillingness to have it discovered, reproved, and spoken against- 6- it is a master sin that makes all other sins stoop and bow to it and subserve as means to feed and maintain it- 7- all your duties are made subservient to- 8- it proves too hard for all means of mortification- 9- one will not part with it for Christ and all His gracious Gospel appeals- 10- it prevails most frequently before, in, and after conversing with God's ordinances and holy duties. We also studied the pastoral disclaimer and distinction of chapter 7, -The Difference Between a Reigning Sin and a Tyrannizing Corruption,- for -some doubting Christians.-
