God's Covenant of Grace: The Mediator Between Two Agreements

A covenant, in its primary sense, signifies a mutual compact or agreement between two parties. Scripture reveals two distinct covenants between God and man: the covenant of works and the covenant of grace.

In the covenant of works, the condition imposed upon man was singular—obedience to the moral law of God. This law demands not merely external compliance with commands, but inward heart-observance of complete holiness. Any deviation from this prescription constitutes an infraction that annuls the entire covenant, rendering it nugatory.

The covenant of grace, by contrast, establishes twofold conditions: repentance and faith. Obedience to the law no longer constitutes the grounds upon which God confers salvation, though the law itself remains eternally valid. As the apostle declares, grace establishes rather than abolishes the law.

From man's fall to the ultimate recovery of redemption, only one covenant operationally governs—the covenant of grace. This second covenant agrees with the first in its ultimate object: everlasting life for man. Yet it differs decisively: a third party is introduced—the Mediator, Christ Jesus himself. Through this Mediator, God's righteousness is satisfied and man's salvation secured. The covenant of grace does not abrogate Yahweh's holiness; rather, it fulfills and vindicates it through the substitutionary work of Christ.
