The document discusses the covenantal nature of God's relationship with mankind and salvation. It explains that God first established a covenant of works with Adam, which was broken, leaving mankind incapable of fulfilling its conditions. To remedy this, God instituted the covenant of grace through Jesus Christ, with faith as the condition. The covenant of grace is the means by which God saves his people through their union with Christ, applying his righteousness to believers. An appropriately covenantal understanding of salvation is necessary for effective evangelism in explaining both God and mankind's role.
