We finish a supplemental study on the Sixth Petition of the Lord's Prayer from the Puritan John Whitlock's sermons through Psalm 18-23 in his book, -The Great Duty of Keeping Ourselves from Iniquity,- with chapters 8-9 regarding special sins, -Some Motives to This Duty- and -Ways and Means to Keep Yourself from Iniquity.- Ch. 8, Motive 1- They will keep your soul from conversion if not a Christian, and if you are, they will much hinder and interrupt your communion with God- 2- They will push to to apostasy if not a Christian, and if you are, they will cause great decays of grace- 3- if you are unconverted, they will most torment your souls in hell forever, and if you are converted, they will cause the greatest wounds and gashes in your consciences here- 5- they will provoke God judicially to give you up to that lust- 6- these are the sins that the men of the world will take occasion from to reproach religion- 7- these are the sins that of all others will most weaken your graces and hinder their growth- and 8- they will most most put a sting into afflictions and into death and the thoughts of it, and make you incapable to bear the thoughts of death comfortably. Chapter 9, Direction 1- Endeavor to get a deep and thorough sense and conviction of the great sin and evil of this your special iniquity- 2- Be earnest and importunate in prayer to God ... for pardon and power ... special grace and strength against your special sins- 3- You who are believers ... add faith in Christ and the lively, vigorous actings of it upon Him- 4- Make use of the sword of the Spirit and the examples of saints- 5- Starve and sever them- 6- Grow in their opposite graces.
