God's response to our sin was covenant—saving, glorious, loving covenant. This is because God is, by nature of being Trinitarian, covenantal. As the Father, Son, and Spirit are a covenantal community as one God, so too they are graciously covenantal with the elect, despite the fact they are sinful enemies and rebels. . . .
When the Bible speaks of God's covenant with his people, it is explaining how our relationship with God is made by his provision and exists by his terms. That God deals with his people in covenant includes all of these glorious truths. Through covenant with God we enjoy a relationship with him that is akin to marriage and includes protection from Satan our enemy, peace with God though we declared war on him through sin, material provision in this life and the life to come, and a coming perfect kingdom as our home where Jesus will forever rule over all as our gracious covenant king. . . .
In a covenant with God there is no bargaining, bartering, or contract negotiations regarding the terms of the covenant. Neither is God's covenant something we must earn by our good works. It is always a gracious provision from the loving Lord to his people. The sovereign Lord of heaven and earth dictates the terms of God's covenants. It is God's covenant in that it is conceived, devised, determined, established, confirmed, and dispensed by God himself, who often says, 'I will establish my covenant with you.' This aspect of God's covenants reveals his sovereign rule as Lord.
