This third volume of Systematic Theology begins with an examination of human beings and their fall away from God. A study of the origin, nature, and effects of sin is followed by a detailed proclamation and exploration of its defeat: God's wondrous provision of salvation through the work of Christ Jesus. Included is an in-depth analysis of all applicable theories and doctrines, such as the extent of the Atonement, the nature of grace, and the assurance of heaven.
