This sixth volume begins with three important works on predestination. The first is A Golden Chain , which treats the main points of theology with an emphasis on “the order of the causes of salvation and damnation.” The second is A Christian and Plain Treatise of the Manner and Order of Predestination , which gives a strident defense of the sovereignty of God in election and reprobation. The third, A Treatise on God’s Free Grace and Man’s Free Will , examines the responsibility of man and how that harmonizes with the will of God in ordaining all things. These treatises showcase Perkins’s scholarly and pastoral concerns on matters vital to the salvation of sinners.
