Pure Tones of the Psalm of Grace
“There is no gift that has not been earned by Him. … The covenant of redemption does not stand by itself, but is the basis of the economy of salvation. It is the great prelude which in the Scriptures resounds from eternity on into our own time and in which we can already listen to the pure tones of the psalm of grace.”
[Geerhardus Vos, “Doctrine of the Covenant in Reformed Theology,” in Covenant and Justification, 133]
